Translating an ISO 1522:2022 pendulum damping test report is not a word-for-word exercise. A coatings laboratory may describe König or Persoz pendulum readings, oscillation counts, damping times, coating panels, cure schedules and conditioning. A translator must make those results readable in another language without silently converting a method-specific measurement into a universal hardness rating. This guide explains how to translate pendulum damping terminology accurately for paint and varnish specifications, supplier inspection records, laboratory certificates and technical disputes.
People searching for how to translate paint hardness test results often encounter deceptively simple words: hard, soft, swing, damping, time, oscillation and pass. In a coating report, each word points to a controlled measurement, a defined instrument or a contractual interpretation. ISO 1522:2022 describes two pendulum damping test methods for paint, varnish and related coatings, including single-layer and multilayer systems. Translating that evidence responsibly means distinguishing a measured response from a product claim, identifying the device, and retaining the test edition instead of replacing it with a similarly named method.
Whether your translation is going into a product data sheet, quality-assurance audit, bilingual laboratory report or purchasing file, the immediate task is specific: preserve the relationship between pendulum, coated specimen, conditions and reported result. This article supplies a practical reader-first translation method, worked example wording, a field-by-field review checklist, a terminology map and realistic scenarios. It is a specialist companion to the wider art of translation, not a new overview of every translation technique.
What the test measures—and what a translation must protect
ISO 1522:2022 is the fourth edition, issued in November 2022. Its official catalogue describes two pendulum damping methods on paints, varnishes and related coatings. A result should therefore be read as evidence of a specified laboratory response of a prepared coating specimen. The catalogue does not grant a translator permission to infer scratch resistance, durability, universal hardness classes or mandatory acceptance thresholds. The full licensed standard, the laboratory procedure and the relevant purchasing specification govern those claims.
For a report reader, an accurate translation must answer six questions before it comments on performance: What specimen was measured? Which pendulum and edition were used? Under what film thickness and preparation? What was recorded and in which unit? How were replicates summarised? What separate customer criterion, if any, was used to judge conformity? If one question has no answer in the source, the translation should not pretend it has been answered.
A field-by-field translation route
Begin with the source document intact. Save a read-only copy and identify its page count, appendices, table headings, approval signatures and revision status. Create a two-column bilingual evidence map. On the left record the original exact wording; on the right write a target-language rendering and a reviewer note when the term is method-specific. This approach protects the relationship among numbers better than translating isolated paragraphs without their tables.
Next mark words that indicate different kinds of information: instructions, observations, interpretations and decisions. The instrument reading is an observation. A specification limit is a criterion. A claim that a batch passes is a decision based on a documented comparison. The reader may need all three, but a translation should not transform one into the other.
Twenty-seven translation decisions that prevent misleading coating reports
1. The standard identifies a test, not a universal hardness scale
ISO 1522:2022 addresses pendulum damping on a coated surface. The result describes how a pendulum’s movement is damped under defined conditions; it does not mean that the surface has been assigned the same kind of hardness number used in pencil scratch, indentation or instrumented nanoindentation tests. A translation that drops ‘pendulum’ risks inviting readers to treat dissimilar laboratory outputs as interchangeable.
If an English report says ‘pendulum hardness’, a concise target-language expression should preserve the test designation and, where needed, explain that damping is the operational principle. Avoid adding a rating such as ‘scratch resistant’ that the particular result did not establish.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With the standard identifies a test, not a universal hardness scale, ask a reviewer to point to the source line for every noun, qualifier and numeric implication. If the reader could reach a materially different purchasing, testing or release decision from the translation than from the original, the rendering needs another pass. Keep a short review record showing the original phrase, the selected equivalent, the reason for the choice and the person who verified any technical assumption.
Imagine a technician, a purchasing manager and a customer reading this section independently. The technician needs a repeatable laboratory description, the manager needs to know what may be compared, and the customer needs to know what the report actually proves. The most reliable translated sentence gives all three access to the same evidence without adopting the strongest possible sales interpretation. In a high-stakes disagreement, that restraint is a practical strength: it allows each party to revisit the test rather than debating an unsupported adjective introduced during translation.
2. König and Persoz are method names, not interchangeable labels
König and Persoz describe two pendulum arrangements associated with this family of coating tests. The names are proper technical identifiers. A reader trying to reproduce a result must know which configuration generated it, because the instruments and counting conventions should not be assumed to yield numerically equivalent readings.
Keep the diacritic in König where publication systems support it, accept a documented transliteration when the target language requires one, and preserve Persoz consistently. Do not translate either name as a descriptive adjective or replace one with the other.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With könig and persoz are method names, not interchangeable labels, ask a reviewer to point to the source line for every noun, qualifier and numeric implication. If the reader could reach a materially different purchasing, testing or release decision from the translation than from the original, the rendering needs another pass. Keep a short review record showing the original phrase, the selected equivalent, the reason for the choice and the person who verified any technical assumption.

The technician needs a repeatable laboratory description, the manager needs to know what may be compared, and the customer needs to know what the report actually proves. The most reliable translated sentence gives all three access to the same evidence without adopting the strongest possible sales interpretation. In a high-stakes disagreement, that restraint is a practical strength: it allows each party to revisit the test rather than debating an unsupported adjective introduced during translation.
3. Oscillation count must retain its counting rule
A laboratory may report a number of oscillations between a defined start and end condition. ‘Oscillations’ are not casually equivalent to individual half-swings, and the distinction matters if a reporter has used turns of phrase such as ‘cycles’, ‘swings’ or ‘passes’. The official method and instrument instructions govern how an oscillation is counted.
Maintain the source count and stated measurement definition. If ’68 swings’ appears where the device output is marked ’68 oscillations’, flag the vocabulary mismatch instead of confidently recoding 68 as 34 or 136.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With oscillation count must retain its counting rule, ask a reviewer to point to the source line for every noun, qualifier and numeric implication. If the reader could reach a materially different purchasing, testing or release decision from the translation than from the original, the rendering needs another pass. Keep a short review record showing the original phrase, the selected equivalent, the reason for the choice and the person who verified any technical assumption.

The most reliable translated sentence gives all three access to the same evidence without adopting the strongest possible sales interpretation. In a high-stakes disagreement, that restraint is a practical strength: it allows each party to revisit the test rather than debating an unsupported adjective introduced during translation.
4. Damping time and number of oscillations are different recorded quantities
A time in seconds and an oscillation count can both describe observed motion, but they are not the same unit or freely convertible without knowing the device’s operating conditions. A result such as ‘144 s’ must not be made to look like ‘144 oscillations’ simply because a translated report template has only one result column.
Keep a dedicated results field for the actual reported quantity, include the unit beside each number and preserve the original instrument identifier. If both time and count appear, present them as two observations rather than a single hardness score.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With damping time and number of oscillations are different recorded quantities, ask a reviewer to point to the source line for every noun, qualifier and numeric implication. If the reader could reach a materially different purchasing, testing or release decision from the translation than from the original, the rendering needs another pass. Keep a short review record showing the original phrase, the selected equivalent, the reason for the choice and the person who verified any technical assumption.

The most reliable translated sentence gives all three access to the same evidence without adopting the strongest possible sales interpretation. In a high-stakes disagreement, that restraint is a practical strength: it allows each party to revisit the test rather than debating an unsupported adjective introduced during translation.
5. Panel substrate belongs to the meaning of the test
A paint film on steel, glass, aluminium or a specified prepared panel is part of the reported context. Mechanical support, surface preparation, coating build and panel geometry can affect interpretation or comparability. A translation that reduces every sample to ‘coating’ removes information needed by a laboratory trying to compare batches.
Render ‘steel test panel’ as a coated steel substrate, not merely a sheet of metal. If the specimen is multilayered, keep the complete coating stack and record whether the measured surface is the final topcoat.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With panel substrate belongs to the meaning of the test, ask a reviewer to point to the source line for every noun, qualifier and numeric implication. If the reader could reach a materially different purchasing, testing or release decision from the translation than from the original, the rendering needs another pass. Keep a short review record showing the original phrase, the selected equivalent, the reason for the choice and the person who verified any technical assumption.
Imagine a technician, a purchasing manager and a customer reading this section independently. The technician needs a repeatable laboratory description, the manager needs to know what may be compared, and the customer needs to know what the report actually proves. The most reliable translated sentence gives all three access to the same evidence without adopting the strongest possible sales interpretation. In a high-stakes disagreement, that restraint is a practical strength: it allows each party to revisit the test rather than debating an unsupported adjective introduced during translation.
6. Dry film thickness is not a decorative specification
Film thickness provides context for a pendulum damping result. A thin application over a hard substrate and a thicker film over a different preparation cannot automatically be compared as though only the formulation changed. In translation, µm belongs to the measurement and must remain attached to its value.
Use ‘dry film thickness’ where the source says DFT and do not silently turn it into wet film thickness. An entry ‘DFT 45 µm’ means a dry-state value, not a 45 millimetre film or a paint application rate.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With dry film thickness is not a decorative specification, ask a reviewer to point to the source line for every noun, qualifier and numeric implication. If the reader could reach a materially different purchasing, testing or release decision from the translation than from the original, the rendering needs another pass. Keep a short review record showing the original phrase, the selected equivalent, the reason for the choice and the person who verified any technical assumption.

The most reliable translated sentence gives all three access to the same evidence without adopting the strongest possible sales interpretation. In a high-stakes disagreement, that restraint is a practical strength: it allows each party to revisit the test rather than debating an unsupported adjective introduced during translation.
7. Cure schedule changes what the result is about
Coating hardness develops over time for many systems. A test performed after a specified number of hours at a stated temperature is evidence about that conditioning history, not a timeless property of a formulation. ‘Cured for seven days’ must not become ‘fully cured’ unless the source actually establishes completion.
Preserve the measured or specified time, temperature and humidity. Distinguish air drying, forced drying, baking and chemical cure where those are explicit. Never infer full cure from the age of a panel.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With cure schedule changes what the result is about, ask a reviewer to point to the source line for every noun, qualifier and numeric implication. If the reader could reach a materially different purchasing, testing or release decision from the translation than from the original, the rendering needs another pass. Keep a short review record showing the original phrase, the selected equivalent, the reason for the choice and the person who verified any technical assumption.

The most reliable translated sentence gives all three access to the same evidence without adopting the strongest possible sales interpretation. In a high-stakes disagreement, that restraint is a practical strength: it allows each party to revisit the test rather than debating an unsupported adjective introduced during translation.
8. Conditioning and test climate need separate fields
The room in which panels are conditioned may not have identical conditions to the moment at which the pendulum is used. Ambiguous drafts often merge ‘conditioning at 23 °C’ and ‘test at 23 °C’ into one claim. Yet readers need to know whether each value described preparation or measurement.
Place each temperature and relative humidity under the correct stage. Preserve tolerance ranges where given; do not convert a laboratory’s nominal set point into an assertion of perfect control.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With conditioning and test climate need separate fields, ask a reviewer to point to the source line for every noun, qualifier and numeric implication. If the reader could reach a materially different purchasing, testing or release decision from the translation than from the original, the rendering needs another pass. Keep a short review record showing the original phrase, the selected equivalent, the reason for the choice and the person who verified any technical assumption.

The most reliable translated sentence gives all three access to the same evidence without adopting the strongest possible sales interpretation. In a high-stakes disagreement, that restraint is a practical strength: it allows each party to revisit the test rather than debating an unsupported adjective introduced during translation.
9. A coating layer is not automatically the entire system
A topcoat may sit above primer and intermediate layers. The pendulum touches the top surface, while the supporting layers form part of the mechanical system. A report describing ‘a single coat over primer’ must not be recast as a single-layer paint film.
Name individual layers and explain the order when the source provides it. A stack written ‘primer / basecoat / clearcoat’ should remain in that sequence so a reader can identify the tested face.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With a coating layer is not automatically the entire system, ask a reviewer to point to the source line for every noun, qualifier and numeric implication. If the reader could reach a materially different purchasing, testing or release decision from the translation than from the original, the rendering needs another pass. Keep a short review record showing the original phrase, the selected equivalent, the reason for the choice and the person who verified any technical assumption.

In a high-stakes disagreement, that restraint is a practical strength: it allows each party to revisit the test rather than debating an unsupported adjective introduced during translation.
10. Pass and fail require an external acceptance criterion
The test method describes a way to obtain evidence. Whether a reading meets a customer’s specification is a separate decision. Some documents establish a minimum, maximum or window; others report results without judgement. Translating a result into ‘compliant’ before checking the contractual limit introduces a decision that did not exist.
Keep ‘measured’ distinct from ‘accepted’. If a purchase order requires at least a stated reading under a named method, quote that criterion separately and confirm instrument and method alignment before declaring conformity.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With pass and fail require an external acceptance criterion, ask a reviewer to point to the source line for every noun, qualifier and numeric implication. If the reader could reach a materially different purchasing, testing or release decision from the translation than from the original, the rendering needs another pass. Keep a short review record showing the original phrase, the selected equivalent, the reason for the choice and the person who verified any technical assumption.

In a high-stakes disagreement, that restraint is a practical strength: it allows each party to revisit the test rather than debating an unsupported adjective introduced during translation.
11. An instrument result is not a general scratch-resistance promise
Users frequently equate high pendulum damping results with better resistance to keys, coins, abrasion or fingernails. Those outcomes involve different loading geometries and damage mechanisms. A translated marketing sheet can mislead readers by presenting the ISO 1522 figure as a universal durability ranking.
When the source reports an instrument value, translate the value and its method. Do not invent ‘scratch proof’, ‘abrasion proof’ or ‘wear-resistant’ unless separately supported.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With an instrument result is not a general scratch-resistance promise, ask a reviewer to point to the source line for every noun, qualifier and numeric implication. If the reader could reach a materially different purchasing, testing or release decision from the translation than from the original, the rendering needs another pass. Keep a short review record showing the original phrase, the selected equivalent, the reason for the choice and the person who verified any technical assumption.

The most reliable translated sentence gives all three access to the same evidence without adopting the strongest possible sales interpretation. In a high-stakes disagreement, that restraint is a practical strength: it allows each party to revisit the test rather than debating an unsupported adjective introduced during translation.
12. Comparisons are only as strong as their shared method
Two coatings can be meaningfully compared within a controlled series, but the translator must watch for differences in pendulum type, conditioning, DFT, substrate, endpoint and reporting convention. If those differ, a numerical ranking may say more about the experimental setup than formulation superiority.
In a supplier comparison, reproduce the original test conditions in adjacent columns. Mark any unmatched conditions as a comparability limitation rather than adjusting the number to force agreement.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With comparisons are only as strong as their shared method, ask a reviewer to point to the source line for every noun, qualifier and numeric implication. If the reader could reach a materially different purchasing, testing or release decision from the translation than from the original, the rendering needs another pass. Keep a short review record showing the original phrase, the selected equivalent, the reason for the choice and the person who verified any technical assumption.

The most reliable translated sentence gives all three access to the same evidence without adopting the strongest possible sales interpretation. In a high-stakes disagreement, that restraint is a practical strength: it allows each party to revisit the test rather than debating an unsupported adjective introduced during translation.
13. The word ‘hardness’ can conceal a direction-of-reading mistake
In some reports a larger count suggests slower damping and a different apparent surface response, but interpretation remains method-specific. The reader should not rely on translated adjectives such as ‘harder’ without verifying exactly which quantity and comparison the laboratory made.
If the source says ‘sample B recorded more oscillations’, translate that observation. When it says ‘sample B is harder’, retain it as the source’s interpretation rather than expanding it to unrelated performance domains.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With the word ‘hardness’ can conceal a direction-of-reading mistake, ask a reviewer to point to the source line for every noun, qualifier and numeric implication. If the reader could reach a materially different purchasing, testing or release decision from the translation than from the original, the rendering needs another pass. Keep a short review record showing the original phrase, the selected equivalent, the reason for the choice and the person who verified any technical assumption.

In a high-stakes disagreement, that restraint is a practical strength: it allows each party to revisit the test rather than debating an unsupported adjective introduced during translation.
14. Specimen identity survives every language change
A production batch code, panel number, coating trade name and sample receipt number may appear near a result. These labels link the number to a physical specimen. Translating or normalising them as ordinary words can break the chain from report to retained sample.
Treat identifiers as controlled data. Keep spelling, case, punctuation and version suffixes unless a documented translation table establishes an approved equivalent. Never substitute a marketing name for a test sample code.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With specimen identity survives every language change, ask a reviewer to point to the source line for every noun, qualifier and numeric implication. If the reader could reach a materially different purchasing, testing or release decision from the translation than from the original, the rendering needs another pass. Keep a short review record showing the original phrase, the selected equivalent, the reason for the choice and the person who verified any technical assumption.

In a high-stakes disagreement, that restraint is a practical strength: it allows each party to revisit the test rather than debating an unsupported adjective introduced during translation.
15. Units and decimal notation need explicit attention
Different languages use periods, commas, spaces and unit spacing differently. A number such as 52.5 should not become 525 when decimal punctuation changes. Seconds, degrees Celsius, micrometres and percent relative humidity must remain unambiguous through layout and editorial conversion.
Use the target audience’s conventional numeric formatting only if the value remains exact. For bilingual certificates, retaining the source notation in a parallel column is often the lowest-risk option.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With units and decimal notation need explicit attention, ask a reviewer to point to the source line for every noun, qualifier and numeric implication. If the reader could reach a materially different purchasing, testing or release decision from the translation than from the original, the rendering needs another pass. Keep a short review record showing the original phrase, the selected equivalent, the reason for the choice and the person who verified any technical assumption.

In a high-stakes disagreement, that restraint is a practical strength: it allows each party to revisit the test rather than debating an unsupported adjective introduced during translation.
16. Uncertainty and repeatability qualify the headline figure
A report may give replicates, a mean, spread or uncertainty statement. That contextual information is not optional background. A single number presented without its dispersion can appear more precise than the experiment supports, especially when two suppliers are separated by only a small difference.
Keep repeat count, mean, minimum, maximum and stated uncertainty labels separate. Never invent uncertainty estimates from a few observations, and do not replace ‘range’ with ‘measurement uncertainty’.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With uncertainty and repeatability qualify the headline figure, ask a reviewer to point to the source line for every noun, qualifier and numeric implication. If the reader could reach a materially different purchasing, testing or release decision from the translation than from the original, the rendering needs another pass. Keep a short review record showing the original phrase, the selected equivalent, the reason for the choice and the person who verified any technical assumption.

17. A graph needs its axes and legend translated as data
A pendulum response graph may show time, oscillations, cure age or coating formulation. A translated figure title without axes can reverse what was varied and what was measured. Colours and plotting symbols also require stable mapping across languages.
Audit axis units, direction, footnotes, sample labels and caption. If the figure is embedded as an image, preserve the original image and supply a companion translated legend rather than distorting values with an unverified redraw.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With a graph needs its axes and legend translated as data, ask a reviewer to point to the source line for every noun, qualifier and numeric implication.

18. A superseded edition should stay in a historical record
ISO 1522:2006 was superseded by ISO 1522:2022. When translating an old test report, silently updating the year creates a false account of the method used at the time. The current edition is relevant for new work, but historical evidence must retain its cited basis.
Write the edition exactly as recorded in the source. If a customer asks whether the test is current, answer that in an editorial note clearly separated from the original report translation.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With a superseded edition should stay in a historical record, ask a reviewer to point to the source line for every noun, qualifier and numeric implication. If the reader could reach a materially different purchasing, testing or release decision from the translation than from the original, the rendering needs another pass.

19. An instrument calibration claim is not a measurement result
A certificate that a pendulum instrument was calibrated and a particular coating’s test value serve different purposes. Calibration information can support confidence in the device, but it does not stand in for a sample result or imply that every panel was tested under identical settings.
Translate the device serial, calibration date, certificate reference and due date as equipment records. Translate the sample reading as test data. Keep both documents linked through identifiers, not through an invented causal guarantee.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With an instrument calibration claim is not a measurement result, ask a reviewer to point to the source line for every noun, qualifier and numeric implication.

20. Test report dates have different meanings
Sampling, panel preparation, coating application, conditioning, measurement, report issuance and later amendment may all have distinct timestamps. A translator can accidentally change chronology by collapsing ‘prepared’ into ‘tested’ or ‘issued’ into ‘certified’.
Use explicit event labels in a bilingual chronology. ISO date formats such as 2026-10-31 help in multinational documents, but any format change should preserve both calendar date and timezone where stated.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With test report dates have different meanings, ask a reviewer to point to the source line for every noun, qualifier and numeric implication.

21. A correction is not a second fresh test
Laboratories may reissue a report to correct a sample name, unit or typographical error. Such an amendment may leave readings unchanged. Calling an amended document ‘retested’ suggests new measurement evidence, even when none occurred.
Preserve revision status and the stated correction reason. Record which pages or fields were replaced, and do not imply a new test unless the laboratory says it performed one.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With a correction is not a second fresh test, ask a reviewer to point to the source line for every noun, qualifier and numeric implication.

22. Marketing wording must not outrun laboratory evidence
Sales copy may ask for a clean phrase such as ‘premium hard finish’. That language is distinct from a measured oscillation count. If the translator merges the two, a technical audience may mistake a marketing impression for an accredited or method-bound measurement.
Keep a result table for evidence and a separate narrative for promotional claims. Add cautious wording such as ‘tested by the pendulum damping method’ rather than equating the result with total service-life protection.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With marketing wording must not outrun laboratory evidence, ask a reviewer to point to the source line for every noun, qualifier and numeric implication.

The technician needs a repeatable laboratory description, the manager needs to know what may be compared, and the customer needs to know what the report actually proves. The most reliable translated sentence gives all three access to the same evidence without adopting the strongest possible sales interpretation. In a high-stakes disagreement, that restraint is a practical strength: it allows each party to revisit the test rather than debating an unsupported adjective introduced during translation.
23. Source-language shorthand needs an authorised expansion
A laboratory worksheet may use labels such as K, P, DFT or RH. Several are ambiguous outside their local context. Expanding a symbol to the wrong term creates a polished but inaccurate text, which can be harder to catch than an untranslated symbol.
Keep the shorthand when uncertain, place a translator’s question near the field and ask the laboratory for its legend. Once verified, create a bilingual termbase so subsequent pages use the same expansion.
A useful verification exercise is to underline the wording that identifies the measured fact in the original, then underline the corresponding wording in the target document. With source-language shorthand needs an authorised expansion, ask a reviewer to point to the source line for every noun, qualifier and numeric implication. If the reader could reach a materially different purchasing, testing or release decision from the translation than from the original, the rendering needs another pass. Keep a short review record showing the original phrase, the selected equivalent, the reason for the choice and the person who verified any technical assumption.

24. Acceptance tables must identify the document that set them
A product specification might require different coating values after distinct cure periods. The ISO test itself is not necessarily the source of those commercial acceptance limits. Translating the contract as if its limits were normative ISO clauses makes future compliance discussions confusing.
Cite the purchase order, customer technical specification or project schedule alongside each threshold. Keep the ISO measurement method as the test reference, not as an invented universal pass mark.

25. Regional-language terminology should preserve method identity
Readers in manufacturing, procurement, laboratory science and consumer marketing do not all use exactly the same vocabulary. The simplest everyday word for ‘hardness’ may lose the experimental nuance of a damping method; the most technical equivalent may obscure meaning for buyers.
Use one precise primary term and a brief parenthetical definition at first mention. After that, keep terminology stable rather than alternating between three near-synonyms in a way that suggests different tests.

26. Multi-language review has to test numbers, not just fluency
A fluent target-language report can be wrong because a unit was lost, a sample number was changed or two tests were conflated. General proofreading rarely catches technical identity errors; numerical and document comparison need their own pass.
Use a bilingual field comparison: ISO edition, instrument, sample, substrate, film thickness, cure conditions, raw result, units, acceptance criterion and document revision. Each field needs an evidence owner.

27. When data is missing, preserve the gap
A translation may be commissioned from a photograph of a laboratory sheet missing the legend or lower half of a table. Guessing the absent measurement conditions may make the page easier to read but destroys the difference between known and inferred facts.
Translate only visible, reliable information, mark illegible text explicitly, and request the original file or annex. The professional answer to a missing number is a traceable query, not a plausible new value.

Worked miniature reports: how to keep evidence and claims separate
Case 1: A result without a method
Source: ‘Hardness: 112.’
Responsible rendering: ‘Hardness value reported as 112; test method and unit not stated in this excerpt.’ Do not add ‘König oscillations’ solely because nearby reports use that apparatus. Ask for the laboratory’s original test designation.
To check the result, create a four-cell review note: source wording, target wording, unchanged evidence, and unresolved question. Ask the second reviewer to compare the numbers and identifiers character by character. A fluent sentence is not enough when a manufacturing release, product claim or customer objection may turn on one altered unit. The final deliverable should make it obvious which assertions come from the laboratory, which come from the contracting parties, and which are editorial cautions.
Case 2: Different panels
Source: ‘Batch A, 58 µm over steel; Batch B, 82 µm over glass.’
Responsible rendering: preserve both dry film thickness values and substrates. A claim that B is more durable is not supported by these conditions alone. A laboratory reviewer may need matched panels before making a formulation comparison.
To check the result, create a four-cell review note: source wording, target wording, unchanged evidence, and unresolved question. Ask the second reviewer to compare the numbers and identifiers character by character. A fluent sentence is not enough when a manufacturing release, product claim or customer objection may turn on one altered unit. The final deliverable should make it obvious which assertions come from the laboratory, which come from the contracting parties, and which are editorial cautions.
Case 3: Old edition on a retained report
Source: ‘ISO 1522:2006.’
Responsible rendering: retain ‘2006’ in the translated historical result. Separately note that the ISO catalogue identifies ISO 1522:2022 as the later edition. Do not backdate a new procedure into an old experiment.
To check the result, create a four-cell review note: source wording, target wording, unchanged evidence, and unresolved question. Ask the second reviewer to compare the numbers and identifiers character by character. A fluent sentence is not enough when a manufacturing release, product claim or customer objection may turn on one altered unit. The final deliverable should make it obvious which assertions come from the laboratory, which come from the contracting parties, and which are editorial cautions.
Case 4: Unspecified shorthand
Source: ‘K 104 / P 248; cured 72h.’
Responsible rendering: retain the K and P abbreviations pending confirmation of the laboratory legend. Record 72 hours of cure without asserting that either numerical value represents seconds, cycles or a universal hardness ranking.
To check the result, create a four-cell review note: source wording, target wording, unchanged evidence, and unresolved question. Ask the second reviewer to compare the numbers and identifiers character by character. A fluent sentence is not enough when a manufacturing release, product claim or customer objection may turn on one altered unit. The final deliverable should make it obvious which assertions come from the laboratory, which come from the contracting parties, and which are editorial cautions.
Case 5: Contractual threshold
Source: ‘Min. 80 oscillations; observed 91; accepted.’
Responsible rendering: show the criterion, observed value and decision in three distinct fields, identifying the contract or specification that established the threshold. Do not make the ISO edition itself the source of a purported universal minimum.
To check the result, create a four-cell review note: source wording, target wording, unchanged evidence, and unresolved question. Ask the second reviewer to compare the numbers and identifiers character by character. A fluent sentence is not enough when a manufacturing release, product claim or customer objection may turn on one altered unit. The final deliverable should make it obvious which assertions come from the laboratory, which come from the contracting parties, and which are editorial cautions.
Case 6: An amended certificate
Source: ‘Revision 02: corrected sample identifier; raw results unchanged.’
Responsible rendering: state that the document was amended and that measurements were not changed. Do not write ‘sample retested’ or ‘recalibrated’ if the record contains no evidence of either event.
To check the result, create a four-cell review note: source wording, target wording, unchanged evidence, and unresolved question. Ask the second reviewer to compare the numbers and identifiers character by character. A fluent sentence is not enough when a manufacturing release, product claim or customer objection may turn on one altered unit. The final deliverable should make it obvious which assertions come from the laboratory, which come from the contracting parties, and which are editorial cautions.
Case 7: Marketing shorthand
Source: ‘Excellent scratch resistance based on pendulum test.’
Responsible rendering: identify the actual reported pendulum damping result and keep the manufacturer’s marketing statement attributed as such. The test may inform coating development, but it is not a general-purpose scratch-resistance test.
To check the result, create a four-cell review note: source wording, target wording, unchanged evidence, and unresolved question. Ask the second reviewer to compare the numbers and identifiers character by character. A fluent sentence is not enough when a manufacturing release, product claim or customer objection may turn on one altered unit. The final deliverable should make it obvious which assertions come from the laboratory, which come from the contracting parties, and which are editorial cautions.
Case 8: A multilingual customer handover
Source: ‘Prepared 01/10, tested 08/10, issued 10/10.’
Responsible rendering: preserve separate preparation, test and issue dates; resolve the day/month convention from document context. A translator who assumes US date ordering in a European record can shift the timeline by months.
To check the result, create a four-cell review note: source wording, target wording, unchanged evidence, and unresolved question. Ask the second reviewer to compare the numbers and identifiers character by character. A fluent sentence is not enough when a manufacturing release, product claim or customer objection may turn on one altered unit. The final deliverable should make it obvious which assertions come from the laboratory, which come from the contracting parties, and which are editorial cautions.
An efficient review plan for a technical translation team
Pass one checks coverage: every section, table, figure, footnote and annex must appear in the target file, or its exclusion must be recorded. Pass two checks identifiers: sample codes, report number, instrument serial, document revisions and method edition. Pass three checks quantities: decimal symbols, units, numbers of replicates, film thicknesses, conditioning temperatures and durations. Pass four checks semantics: observation versus comparison, a measurement versus an interpretation, and a customer acceptance criterion versus test method wording.
Pass five checks the reader experience. A production engineer should be able to reconstruct what was tested without consulting the translator. A procurement reader should understand the limitations of comparing two suppliers. A customer should be able to locate the stated acceptance rule. If the source omits a critical field, the target should call attention to the omission with a question instead of repairing the source by invention.
Frequently asked questions
Is pendulum hardness the same as pencil hardness?
No. The names describe different measurements. Pencil hardness uses a graded pencil interaction with a coating, while ISO 1522 concerns pendulum damping. Translating both simply as ‘hardness’ without method labels can wrongly encourage numerical comparison. Preserve the exact named test.
For quality assurance, note the original page, the responsible reviewer and any decision that still needs the laboratory’s confirmation. This makes the answer useful in a real bilingual handover rather than a generic definition.
Can I convert König counts into Persoz counts?
Do not invent a universal conversion. The two pendulum arrangements are method-specific and the underlying procedures and readings are not automatically interchangeable. A validated correlation for a defined laboratory and product family, if available, is a separate technical document.
For quality assurance, note the original page, the responsible reviewer and any decision that still needs the laboratory’s confirmation. This makes the answer useful in a real bilingual handover rather than a generic definition.
Does the newest ISO edition replace the cited edition in an old report?
No. The original record should retain its historical edition. The current ISO 1522:2022 edition may be mentioned as a separate editorial fact, but silently changing 2006 to 2022 would misstate how the earlier test was described.
For quality assurance, note the original page, the responsible reviewer and any decision that still needs the laboratory’s confirmation. This makes the answer useful in a real bilingual handover rather than a generic definition.
What if a report has a value but no unit?
Check whether the method and instrument present a count or a time. Do not assign seconds because they look familiar, and do not add oscillations without evidence. Ask for the original output and retain the source ambiguity until it is resolved.
For quality assurance, note the original page, the responsible reviewer and any decision that still needs the laboratory’s confirmation. This makes the answer useful in a real bilingual handover rather than a generic definition.
What if the customer requests a pass/fail summary?
First locate an acceptance criterion in the contract or specification that actually applies to the named method, coating and conditioning. The translation should show the measured result and the contractual rule separately, then state an interpretation only when authorised.
For quality assurance, note the original page, the responsible reviewer and any decision that still needs the laboratory’s confirmation. This makes the answer useful in a real bilingual handover rather than a generic definition.
Should a translator localise test sample identifiers?
Normally the identifiers are kept exactly because they connect the report to production and laboratory records. Descriptive sample names may be explained, but alphanumeric codes should not be retranslated or reformatted without a controlled mapping.
For quality assurance, note the original page, the responsible reviewer and any decision that still needs the laboratory’s confirmation. This makes the answer useful in a real bilingual handover rather than a generic definition.
Why does dry film thickness matter in a language task?
Because the sentence is about experimental evidence rather than an isolated property. A test performed on a 35 µm film and one on a substantially different coating system may not support a simple supplier ranking. Preserve DFT with its unit and coating context.
For quality assurance, note the original page, the responsible reviewer and any decision that still needs the laboratory’s confirmation. This makes the answer useful in a real bilingual handover rather than a generic definition.
How should a bilingual report handle uncertainty?
Use equivalent terms for average, replicate, range, standard deviation and reported measurement uncertainty only when those are actually present. Do not infer one from another. Retain the number of specimens, rounding and coverage information, if supplied.
For quality assurance, note the original page, the responsible reviewer and any decision that still needs the laboratory’s confirmation. This makes the answer useful in a real bilingual handover rather than a generic definition.
Four-week practice route
Week 1: assemble three anonymised sample reports and build a bilingual glossary of method terms, instruments, units and specimen identifiers; verify every abbreviation against its source legend.
Week 2: translate one complete report including tables, figures and appendices; record questions instead of guessing missing test conditions; compare every numeric field against the original.
Week 3: practise difficult reader scenarios: two pendulum types, two cure schedules, different film thicknesses, an amended certificate and a contract containing a pass/fail limit.
Week 4: run an independent blind review with a coatings specialist. Revise the target text based on evidence, document every correction and build a controlled glossary for the next report.
