To translate an ISO 1920-5:2018 concrete test report accurately, distinguish hardened-concrete density from water penetration depth before choosing equivalent terminology in another language. People searching for “ISO 1920-5 translation,” “hardened concrete density test report in English,” “water penetration depth in mm,” and “concrete water pressure test results” usually need to interpret a specific laboratory certificate. A faithful translation keeps each specimen, measured property, numeric value, unit, test condition and qualification attached to its original evidence.
Construction laboratories, engineers, concrete suppliers and international buyers regularly handle reports that contain similar-looking numbers describing different things. The same page may show the mass and volume of a specimen, its density in kg/m³, its overall thickness in mm, the maximum observed water penetration depth in mm and an applied pressure expressed in MPa. Reversing two headings can make a correct-looking bilingual report materially false. This article explains how to avoid those mistakes in clear, evidence-led language.
ISO 1920-5:2018 is titled “Testing of concrete — Part 5: Density and water penetration depth.” The ISO public catalogue states that it specifies methods for testing density and water penetration depth of hardened concrete. The 2018 edition was reviewed and confirmed in 2023. Our purpose is to explain the meaning of associated laboratory records, not to reproduce licensed standard clauses, prescribe testing equipment or manufacture a universal concrete acceptance criterion. All numbers in worked examples are hypothetical rather than actual project results.
1. The tested object: hardened concrete rather than a general building material
Hardened concrete describes a particular state of concrete. It is different from freshly mixed concrete, concrete ingredients such as cement, and an installed structure as a whole. A source might also identify whether a specimen was cast for testing or taken from existing construction. Preserve those details, because they define which material and physical object the subsequent numbers describe. A translation that calls a hardened specimen “fresh cement” changes the subject before the reader even reaches the measurements.
Suppose an invented entry reads “Hardened-concrete specimen C-07 submitted for density determination.” The misleading version “Fresh cement batch C-07 approved for strength” introduces three unsupported changes: material state, measured property and acceptance. A better version names the hardened specimen and density purpose without implying a verdict. Keep any batch connection separately identified when the report provides one. One specimen does not automatically represent every location within a construction project.
2. Density means mass relative to volume
Density is mass per unit volume. A concrete density value can be expressed in kg/m³, and its physical meaning differs from compressive strength. The source’s mass, volume and density fields may be connected, but they are not interchangeable nouns. A fictional measured mass of 7.2 kg divided by a volume of 0.003 m³ produces a density of 2,400 kg/m³. This example illustrates dimensional arithmetic, not any particular procedure specified by ISO.
If a report states density of 2,400 kg/m³, do not translate it as “strength 2,400 MPa” or “specimen mass 2,400 kg.” Those are different quantities. The accurate target sentence preserves “density” and its mass-per-volume unit, along with specimen identity and reported condition. Engineers can later assess whether the result is relevant to an application, but language conversion does not authorize a claim that a denser specimen is necessarily stronger or more durable.
3. Nominal dimensions and measured volume
A certificate might show nominal specimen dimensions, measured lengths, an estimated or calculated volume, and a density result. A nominal dimension describes a designation, while a measured dimension describes an observation. They can look similar but should not be silently swapped. When the report distinguishes them, the translated version must do the same. This is particularly important for scanned tables that use abbreviated headings and for documents where a drawing gives geometry rather than volume.
For example, a fictional specimen described as “nominally 150 mm” may have separately recorded measured dimensions. A translation that substitutes the nominal value for every actual measurement loses information about how the laboratory described its specimen. If the numbers do not reconcile with a simple calculation, record the discrepancy and request clarification instead of rewriting an authorized result to make the arithmetic convenient. The translator explains what the source reports; the laboratory owns its calculation.
4. Moisture condition and density context
Concrete specimens may have different moisture conditions and preparation histories. A source could describe material as received, dried, surface dry, conditioned or saturated, each with context-specific meaning. The translator should not treat these as a single generic word meaning “prepared.” A density result without its associated recorded state can be difficult to compare with another result. Preserve the source’s exact specimen-condition term, and use its laboratory definition when available.
Imagine a source stating “specimen mass recorded after conditioning.” A careless translation may assert “fully oven-dried concrete,” even though no oven-drying is mentioned. The responsible version states that the measurement occurred after the reported conditioning and retains any separate condition note. If an appendix is missing, ask for it rather than supplying a familiar procedure from a different report. Moisture history is potentially relevant, but the translator must not infer the history.
5. Water penetration depth is a length
Water penetration depth reports how far water is observed to penetrate a concrete specimen under the documented test conditions. When expressed in millimetres, it is a length rather than a percentage, water volume or mass. It is not the same as water absorption or hydraulic conductivity. This distinction is easy to lose when an everyday-language term for water ingress is used indiscriminately for several test quantities.
A fictional result might state “maximum observed water penetration depth 24 mm.” Writing “24% moisture absorption” changes both the property and the unit. Writing “a building will admit 24 mm of rainfall” extrapolates incorrectly from specimen evidence to an installed structure. A useful target sentence reports the maximum observed depth in the identified specimen under the stated test arrangement, without constructing a performance guarantee that does not appear in the source.
6. Maximum depth and average depth are different statistics
The word maximum must not disappear when a laboratory reports its largest observed water penetration depth. An average, a minimum, an individual local measurement and a maximum are different summaries. In a made-up teaching set of local observations of 11, 15, 18 and 24 mm, the maximum is 24 mm and the simple arithmetic mean is 17 mm. This arithmetic does not prescribe how ISO measurements are reported; it shows why the selected statistic matters.
If a translated summary substitutes the mean for the maximum because it looks more favourable, the text no longer expresses the original result. Conversely, a source value labelled “mean” should not be presented as an extreme. When the original document includes a drawing, ensure the labels on the observed penetration front, table and narrative agree. Preserve the laboratory’s calculation and aggregation labels rather than improvising a new summary.
7. Applied water pressure is not compressive strength
Applied water pressure may be a condition during a water penetration test. It can be expressed in kPa, MPa or other pressure units. Compressive strength may also use MPa, but that unit similarity does not make the properties identical. A fictional report might give applied pressure 0.5 MPa in one table and compressive strength 38 MPa from another test. The correct translation assigns each number to its actual physical role.
An error such as “concrete strength 0.5 MPa” could create a completely false engineering story. Check the source heading and laboratory method before accepting a value just because the unit appears familiar. If the file contains more than one test, keep the method references and specimen IDs separate. A bilingual conclusion should say “applied water-pressure condition” when that is what the original actually describes.
8. Exposure time, test age and curing period
A water penetration test record may contain an exposure duration, while a specimen history can include casting date, curing period, sample receipt date and age at testing. These are not synonyms. If a report identifies an exposure time, keep it attached to the measured result. If a specimen is described as a given number of days old, do not interpret that as the duration of water pressure exposure. Chronology matters to the meaning of the evidence.
For a fictional record saying “exposure conditions listed in Annex B,” retain that cross-reference. If the annex is unavailable, do not guess the time or pressure and claim that it came from the standard. A translated certificate can disclose that the source excerpt lacks the information. Preserving uncertainty is more responsible than making the text artificially complete. It lets the engineer request the missing record rather than rely on an invented condition.
9. Penetration depth is not a permeability coefficient
Permeability, water absorption, depth of penetration and hydraulic conductivity are related to water behaviour but measure or describe different things. A depth written in mm must not be relabelled a permeability coefficient without a legitimate separate measurement or model. Technical terms may be similar in ordinary language, yet their units and purposes differ. An accurate glossary should list them separately with a sentence defining each.
If a result says “water penetration depth: 18 mm,” a translation saying “permeability: 18 mm” changes the quantity. A better target wording preserves the depth and the test context. Where a separate project document includes a permeability value, translate that under its own method and unit. Doing so avoids a common form of cannibalization inside the report itself, where one property is made to stand for all water-resistance characteristics.
10. Waterproofness is not automatically established
Words such as waterproof, watertight, impermeable and water-resistant can imply strong claims about a completed structure. A laboratory measurement on a concrete specimen does not automatically validate a whole roof, basement or tunnel lining. Installed structures include joints, penetrations, cracks, workmanship and exposure conditions that go beyond an isolated specimen. The translator should not turn a narrow laboratory record into an enduring warranty.
Consider a fictitious result “maximum penetration depth 20 mm.” The headline “ISO certified the building is completely waterproof” adds a certification and changes specimen evidence into building-level assurance. A faithful translation reports the tested specimen, result and associated conditions. If the source includes a separate contract-based acceptance decision, that can be translated as an attributed decision, not silently inserted into a measured-value row.
11. Specimen thickness and penetration depth can both use mm
The same report may list specimen thickness, diameter, crack width, edge distance and water penetration depth, all in millimetres. The unit alone cannot identify the quantity. A hypothetical specimen may be 150 mm thick while its maximum observed penetration depth is 24 mm. A column shift in a translated PDF could wrongly assign the 150 mm figure to penetration and leave every digit and unit technically copied.
Prevent this by creating an internal inventory of quantity labels and their source positions. Verify that the specimen thickness stays in the geometry field and penetration stays in the result field. Compare any figures or sketches with the source table. Do not infer meanings based on which number seems plausible. The function of a value comes from its heading, method context and specimen association.
12. Cubes, cylinders and cores should remain distinct
Concrete reports can refer to cubes, cylinders and extracted cores. These terms describe shape or provenance, not stylistic alternatives for “block.” A core may have been taken from existing construction, while a laboratory-made specimen has another preparation history. A translation that changes “cylindrical core” to “cube” changes the physical object. Keep dimensions such as diameter, height and thickness properly named.
A made-up entry “core C-14, nominal diameter 100 mm” should not become “100 mm concrete cube.” Keep the source geometry and identifier. Even when a photograph appears to show a cylindrical object, do not infer how it was obtained without a sampling record. A report may have separate specimen-origin fields, and those details should remain traceable alongside the density or water penetration result.
13. Different tests may use different specimen groups
The standard title contains two properties, but a laboratory may use different specimen IDs for density and penetration. A translator should not combine a density from one group with the water penetration depth of another simply to shorten an executive summary. The same project number does not prove that each result belongs to the same physical object. Distinguish specimen identity in every table and concluding sentence.
Imagine a fictional certificate with density readings on D-01 and D-02 and water penetration readings on P-01 and P-02. A sentence claiming “D-01 showed 24 mm penetration” is false unless the source explicitly links those observations. Separate the result families or have a technical owner confirm their relationship. This discipline protects traceability for suppliers, buyers and investigators reviewing the document years later.
14. Visible cracks and specimen conditions are observations
A lab may record cracks, voids, chipped edges or other visible features. Such details can be relevant to interpretation, but translating “a crack was observed” into “the crack caused test failure” adds causal judgment. Preserve the observation, timing and location, along with the laboratory’s own assessment if provided. Do not assign responsibility for a defect merely because it appears in a report photograph.
An invented source caption reads “surface crack visible after testing.” The careless translation “structural failure occurred in the building” expands a specimen observation into a construction event. A faithful caption names the tested specimen and the visible feature. If the source uses cautious language such as “possible influence,” preserve that uncertainty. Technical explanations may add context, but they must not invent an engineering finding.
15. Image captions, diagrams and scales are evidence
Some laboratory reports include photographs of split or examined specimens, marked water penetration regions and diagrams of specimen dimensions. The captions and arrows should be translated in context. A correct numerical table paired with the wrong specimen photo can be misleading. During localization, ensure that any scale, identifier, symbol or line annotation remains visually connected to the right observation.
A cropped diagram may show 150 mm overall thickness and 24 mm penetration depth. If the label for 24 mm is moved to the outer dimension, the visual report changes meaning without an obvious text error. Review the final PDF or web-rendered report, not just the word-processing file. Never estimate an official depth from a photograph lacking a reliable scale. Where the figure and source table disagree, request clarification rather than silently choosing one.
16. Numbers and units need their own audit
For density, 2,400 kg/m³ equals 2.4 g/cm³. For length, 25 mm equals 2.5 cm. For pressure, 1 MPa equals 1,000 kPa. These dimensional relationships can help check a translation, but the original unit should remain traceable. An error can arise when the unit is converted but the number is not, or when a decimal comma is interpreted as a thousands separator.
Maintain a number-and-unit inventory covering every result, condition, specimen dimension, table footnote and graph axis. Review inequalities as carefully as digits. A source stating “less than 10 mm” must not become “10 mm exactly.” A source stating “not tested” cannot become “0 mm.” The arithmetic check and semantic check are separate: each number must be mathematically coherent and attached to the correct physical quantity.
17. Every reported test needs a specimen identifier
A project can contain many batches and specimens. A density number on one sheet may belong to a different specimen from a penetration depth on the next. Keep project codes, pour identifiers, batch numbers, core labels and individual specimen codes distinct. An alphanumeric identifier should usually be copied exactly, including its leading zeros and suffix. Do not translate a code as though it were ordinary prose. The aim is to allow a future engineer or auditor to follow the translated figure back to the physical object originally tested.
Imagine a made-up report listing density on specimen D-02 and penetration depth on P-02. It is tempting to write a single sentence about “sample 02,” but that wording conceals the distinct identifiers. Unless the laboratory explicitly links the two samples, retain their separate entries. If the source identifies one batch as the origin of both, report that relationship as stated. A good translation makes the hierarchy understandable without pretending all measurements came from the same concrete piece.
18. Sampling location does not mean testing location
A report may list the place where concrete was sampled, the laboratory where the specimen was tested, and the project where the material will be used. These locations have different roles. A specimen extracted from a structure is not necessarily tested at the construction site, and a laboratory address does not identify the sampling origin. Translate location labels and keep the underlying codes unchanged, particularly where grid references, floor levels or component designations might determine which part of a project is under review.
A fictional source might record “sampling location: Tower A, Grid B7; testing laboratory: Central Materials Lab.” A poor rendering merges them into “Tower A Laboratory.” The corrected version preserves two locations with their functions. If the document does not identify the exact collection point, do not derive one from a map or general project description. Traceability depends on respecting the difference between an origin and a place where analysis occurred.
19. Source dates form a chronology
A report may identify the date of casting, sampling, specimen receipt, conditioning, testing, approval and issuance. The chronological sequence is not just administrative decoration. A specimen’s reported age at testing cannot safely be inferred from the date the laboratory received it. A translation that changes the receipt date into the casting date can fabricate an age or imply the wrong preparation history. Every date should retain its event label even when the format changes for international readers.
For example, “received 12 October; tested 18 October” does not show that concrete was six days old. The material may have been cast much earlier. If the source uses 04/05/2026, identify its locale before deciding whether this means April 5 or May 4. Use unambiguous month names where helpful, but preserve the original date in an audit record. Chronological accuracy is as important as number accuracy when test conditions influence interpretation.
20. A method reference is not a product certification
The line “tested according to ISO 1920-5:2018” identifies the laboratory’s reported method basis. It is not automatically a declaration that ISO approved the concrete, that the producer has an ISO product certificate, or that the structure passed a regulatory inspection. A test method specifies how a property may be determined; a product or project specification may set a separate acceptance criterion. Language should not erase that distinction by replacing the words “tested according to” with “certified by.”
When a source contains a real pass/fail decision, preserve who made it and which requirement it applied. An engineer’s project-specific acceptance statement is not the same as an international standards body’s endorsement. If no decision is present, the translation should stop at the measurement. This approach can be conversational and useful: “The laboratory reported this test result. The certificate does not state whether it satisfies a separate project limit.” The reader knows exactly what is established and what still needs evaluation.
21. Reported acceptance criteria belong to a named requirement
A buyer may specify a maximum permissible penetration depth, or a density interval, for a particular product or contract. Such criteria must be translated with their source and conditions. Do not treat a number in a buyer’s specification as though it were an ISO 1920-5 universal threshold. The same measured value may be assessed differently under different legitimate project requirements. A translator should show the measurement and any documented acceptance comparison as two related but distinct statements.
Suppose an invented project specification asks for a depth not exceeding 25 mm under its specified arrangement, and the laboratory reports 20 mm. A target-language summary can state the comparison if the source authorizes it. If the source report contains only “20 mm” and no such specification, the translation cannot add “pass” on the translator’s initiative. An attractive green tick in a table may be just as misleading as an unsupported sentence; design elements must reflect the evidence too.
22. The word resistance requires an object
A source may refer to resistance to water penetration, compressive resistance or resistance to another action. Translating all of these as the generic word “resistance” makes it difficult to know what the result concerns. Prefer an explicit technical noun phrase, especially in headings or executive summaries viewed without full context. A target sentence should answer “resistance to what?” before offering a value. This is not verbosity for its own sake; it prevents the reader from substituting an entirely different measured property.
A fictional label “resistance to water penetration, specimen P-04” should not become “pressure resistance of concrete” merely because the laboratory applied pressure. The latter could be read as a mechanical-strength claim. When a source expression is unusual, retain its method context and consider a short explanatory note. If the author uses a term inconsistently, ask which meaning is intended rather than silently choosing whichever equivalent appears most conventional.
23. The meaning of a laboratory’s maximum observation
Maximum depth should be distinguished from an individual local reading, a visually estimated front and an average of several values. If a sketch displays more than one penetration measurement, it does not automatically establish which statistic the laboratory reported. The translator should keep the source’s actual summary label and avoid computing a substitute result from a partial diagram. Where the laboratory separately provides a figure caption and a table, verify they refer to the same specimen and observation.
Consider original teaching observations of 12, 16, 18 and 25 mm. The largest is 25 mm while the arithmetic mean is 17.75 mm. These invented values illustrate words, not a required ISO reporting process. A draft that presents 17.75 mm as the maximum would change the evidence, even if the calculation itself were correct. Good translation preserves the author’s selected statistic while allowing a reader to see that alternative statistics answer different questions.
24. Visual observations should not become causal conclusions
A source can say that a crack was observed, that a specimen had a chipped edge, or that an irregular penetration boundary was visible. These are observations. A stronger claim that the crack caused a particular result needs separate support. Avoid upgrading tentative phrases such as “may have contributed” into “was responsible for.” Technical readers may use the translated statement in a dispute, so a change in certainty can change more than the writing style.
Imagine a report note “crack observed on cut face after test.” A mistranslation says “crack proved construction failure and caused penetration.” The corrected description retains what was visible, where and when. If the laboratory interpreted the crack, translate that separate interpretation with its own qualification. Do not diagnose a building from a single specimen photograph. The translator’s job is to preserve the source’s level of evidence, not to generate a more dramatic narrative.
25. Photographs and charts need line-by-line verification
A figure may show a specimen, a penetration front, a scale or arrows for thickness and depth. It can become misleading when a caption is moved under another image during translation. Check every figure number, specimen code, measurement arrow, scale and unit against the source. The final exported PDF or webpage matters as much as the text draft because typography and image placement can change meaning without changing the words.
A photograph with a visible 150 mm specimen dimension and a 24 mm depth mark should not be captioned as “water penetration 150 mm.” If a scale is absent, do not estimate an official penetration depth by eye. Where the image and the results table appear inconsistent, document the discrepancy and ask the issuing laboratory for a correction. A translator must not invent a neat reconciliation from an ambiguous visual.
26. Convert density units without creating a new result
For density, 1 g/cm³ equals 1,000 kg/m³. Thus 2,400 kg/m³ is equivalent to 2.4 g/cm³. This conversion is useful when the target audience expects a different unit, but it should be labelled as a conversion rather than silently replacing the source. Check the number of significant figures and any specimen condition. A translation should not add trailing zeros that imply more precision than the laboratory reported.
A further risk is local numeric formatting. Commas can mark decimal fractions or thousands depending on the language and country. The text “2,400 kg/m³” must be rendered so the receiving reader interprets the intended quantity, not 2.400 kg/m³. Compare the source’s field definition and context, and if ambiguity remains, query the author. A unit conversion is only as useful as the number to which it is attached.
27. Depth conversion is not percent conversion
A penetration depth of 25 mm equals 2.5 cm. It does not automatically equal 25% penetration, because a percentage needs a defined denominator. The report may also list specimen thickness, but that does not permit the translator to replace the measured depth with a ratio unless the source defines a legitimate derived quantity and its basis. The same error can occur when a marketing summary prefers percentages to lengths.
Suppose a specimen is 150 mm thick and the recorded penetration depth is 24 mm. A translator may be tempted to say “16% water-resistant.” This is an invented property with no support in the source. If a numerical ratio is pedagogically useful, label it explicitly as an illustrative ratio of two lengths rather than the laboratory’s result or a resistance rating. In a published technical translation, the safest default is to retain the reported penetration depth.
28. Pressure conversions require care
Pressure units such as MPa, kPa and bar can be converted, but a relabelled unit without a corresponding numerical conversion changes the result. Since 1 MPa equals 1,000 kPa, an applied water pressure of 0.5 MPa corresponds to 500 kPa. These are teaching conversions, not prescribed pressure settings for the ISO method. The actual test pressure must come from the source report or authorized procedure.
It is also essential to preserve what the pressure describes. A value in MPa might be a water-exposure condition on one page and a strength result under another test on the next. A bilingual number-and-unit inventory should list the quantity name, source location, numeric value and unit. If any entry changes during translation, document why. Merely spotting “MPa” in both documents is not enough to infer equivalence.
29. Approximate, less than and not measurable
Scientific and technical reports can qualify a value as approximate, below a stated limit, greater than a bound, or not determinable. These expressions cannot be discarded to create a polished exact number. If the source says “penetration depth < 10 mm,” the target must retain “less than 10 mm,” not “10 mm.” If a depth was not measurable under the reporting arrangement, do not report it as zero without a source statement.
Typography can make this error easy. A less-than sign may disappear in a PDF export or become confused with a decorative arrow. Check inequalities separately from ordinary proofreading, especially in tables and figure captions. A bound can affect a project’s acceptance interpretation; its direction and relation to the value are evidence. It is better to state a qualified measurement clearly than to create false precision by omitting a short symbol.
30. Compare results only when conditions support comparison
Two laboratories may have tested different specimen conditions, ages or arrangements, even when both reports cite the same method family. A difference in density or penetration depth can be described without claiming a cause or universal ranking. A translator should preserve relevant context: specimen origin, age, moisture state, actual measurement conditions and any stated uncertainty or limitation. Omission may make the data seem more directly comparable than the source allows.
A fictional comparison gives batch A density 2,350 kg/m³ and batch B 2,390 kg/m³. The accurate statement is that the reported values differ by 40 kg/m³, subject to comparable conditions. The inaccurate statement is that B is necessarily stronger or waterproof. Likewise, a lower penetration depth under one arrangement does not settle every question about long-term structural performance. Keep the observation distinct from the engineering conclusion.
31. Version control prevents hybrid certificates
A source report may be amended because a specimen label, calculated figure or administrative detail changed. If the translated cover page reflects a revision but the appendix still contains data from the original version, the delivered document may not match any authorized laboratory record. Record issue date, amendment number, supersession statement and the client’s authorized version before drafting. A correction note should remain attached to the corrected information.
For example, an initial fictional report shows density 2,360 kg/m³ and a revised report 2,365 kg/m³. The translator should use the authoritative version rather than the numerically more appealing one. If the recipient needs both historical versions, identify them separately. Do not silently merge a new table with old captions. This practical discipline matters for engineering audits and legal archives long after the original translation has been prepared.
32. A complete workflow for reading and translating the certificate
First preserve the source file and its version information. Next extract specimen IDs, sample origins, measurement families and units into a structured inventory. Third read the laboratory’s method references and any annex descriptions without assuming missing procedural details. Fourth build a term glossary separating density, mass, volume, pressure, thickness, water penetration depth, absorption, permeability and strength. Fifth draft clear target-language sentences in which each result remains attached to the correct specimen and condition.
Sixth conduct a separate numerical audit covering decimal separators, conversions, inequality signs, missing values and table headings. Seventh compare images, captions, scale marks and page numbers against the source after export. Eighth review claims of compliance, approval, certification or causation against the actual wording and relevant project criterion. Finally refer technical inconsistencies to the issuing laboratory or engineer. A translator may flag an apparent error but should not silently amend signed laboratory evidence.
33. Four-week practice route for this specific task
In week one, learn the five principal concepts: hardened concrete, density, water penetration depth, applied pressure and compressive strength. Write one original sentence for each showing the right kind of unit. In week two, practise simple hypothetical mass-volume calculations and conversions among kg/m³, g/cm³, mm, cm, MPa and kPa. Use a source-versus-target table to prevent values and units from being separated.
In week three, translate fictional notes about specimen condition, age, curing, crack observations, missing values and amended reports. For each, identify an incorrect but plausible rendering and explain precisely what it changed. In week four, review a simulated multilingual certificate with separate specimen groups, a penetration diagram, density figures and a project acceptance statement. Ask another reader to reconstruct the same evidence from the translation without needing the original language.
Frequently asked questions
Is water penetration depth the same as permeability?
No. Penetration depth is a length observed under the test arrangement, while permeability or hydraulic conductivity denotes a different physical property. A translator should not replace one term with the other or fabricate a coefficient from a millimetre result. Keep each measurement and method separately identified.
Does ISO 1920-5 automatically mean a product has passed?
No. It identifies methods for testing density and water penetration depth of hardened concrete. A source may contain an independent project specification and an authorized conformity decision, but the method citation alone does not establish a universal pass requirement for every concrete application.
Can pressure in MPa be treated as compressive strength?
No. A pressure applied during a water penetration test is a testing condition. Compressive strength is a different property. The same unit can express different roles, so keep the named quantity, source method, specimen and relevant table heading together.
Why do sample age and moisture condition matter?
They are part of the specimen’s history and may matter when interpreting or comparing results. Preserve whatever the laboratory actually reports. Do not substitute a common test age or assume that a conditioned specimen was oven-dried unless the source explicitly says so.
What if a table contains N/T?
Check the source legend. It may mean “not tested,” and it must not be converted to a numeric zero. An unavailable observation is different from a valid result of zero water penetration. If the abbreviation remains ambiguous, keep an issue note and ask the laboratory.
Can I publish the translation from machine output alone?
Automated translation can help with a draft, but it may lose units, reverse columns, misplace inequalities or exaggerate the conclusion. Human verification against the signed source is essential for consequential engineering, procurement or contractual use.
What if the lab report and figure disagree?
Do not silently choose the value that seems most plausible. Check whether they describe different specimens or different kinds of measurements. If the inconsistency remains, record the exact table and figure references and request an authorized correction or clarification.
Can one penetration depth certify an entire structure as waterproof?
No. The laboratory result concerns an identified specimen under defined conditions. A completed structure includes many additional factors, including joints, workmanship and exposure history. Keep any real structure-level claim separate and attributed to its actual author.

The broader method of preserving meaning across language boundaries belongs to the established Master Art of Translation. For language foundations, continue to the protected Vocabulary Learning Hub and How English Works: Translation and Meaning Across Languages. This guide solves one narrow technical search intent; it does not create a competing broad hub.
A dependable translation allows the next reader to identify the same specimen, the same measured quantity, the same unit and the same limits of inference as the original report. It is readable because it has retained structure, not because it has erased uncertainty. Every numerical result should remain connected to the laboratory observation that gives it meaning.
