Turn “it passed” into evidence another reviewer can inspect
Use FDA’s non-clinical bench-testing guidance through objectives, specimens, protocols, methods, acceptance criteria, sample rationale, results, deviations and complete reports.
Before a medical device reaches patients, many performance questions can be challenged on a laboratory bench. A joint may be cycled, a seal may be pressurised, a sensor may be compared with a reference or a material may be loaded until failure.
FDA’s December 2019 final guidance explains how non-clinical bench performance information should be organised in premarket submissions. Its useful lesson reaches beyond regulation: a result becomes credible when readers can see what was tested, how, against which criterion and with what outcome.
Did you know? A test report can contain a passing conclusion and still be hard to evaluate if the tested device version, acceptance criteria, deviations or individual results are unclear. Reporting quality is part of evidence quality.
This guide supports experimental and reporting literacy. It does not determine which tests a specific device submission requires.

Chapters 10–17: criteria, results, deviations and reporting
A bench result becomes reviewable when the question, protocol, acceptance criteria and result remain connected. FDA’s guidance describes recommended information for summaries, protocols and complete reports of non-clinical bench performance testing in premarket submissions. This turns a claim of “passed” into inspectable evidence.

A strong bench conclusion preserves the path from requirement to result
Bench evidence is more than a final number. It is a chain joining the device requirement, representative specimen, controlled method, predefined criterion, observed data and bounded conclusion.
Save the device and specimen identity, manufacturing and conditioning state, protocol version, objective, test standard and edition, modifications, equipment and calibration, environment, sample-size rationale, acceptance criteria and basis, individual and summary results, deviations, exclusions, failures, analysis, conclusion and approvals.
| Reading object | What it can support | Question to keep visible |
|---|---|---|
| Test summary | Gives a concise evidence route | Does it name the key conditions and result? |
| Protocol | Defines planned conduct | Were criteria set before interpretation? |
| Complete report | Documents conduct and data | Can exceptions and calculations be followed? |
| Conclusion | States the supported performance claim | Does it stay inside the tested boundary? |
Sources and next reading
Substantive resource claims in this article were checked against the primary pages below. A structured record is a route into evidence; it does not by itself prove a scientific conclusion. Recheck the live record, evidence labels and release context before using it in assessed work or research.
For a classroom enquiry, save a short research receipt containing the question, search terms, selected object, exact identifier, version, access date and the evidence boundary you observed. Add the file or page that supports each statement. This small routine turns browsing into accountable science learning and gives a teacher, classmate or future analyst a route they can independently follow.
Before sharing the conclusion, ask another reader to retrace the route without verbal hints. If they reach a different version, file or interpretation, improve the receipt and narrow the claim. Reproducibility begins with this practical check. It teaches careful reading, supports fair collaboration and keeps uncertainty visible while evidence moves from an online service into notes, analysis and a final explanation.
A useful final review separates five questions. What object was found? Which organisation or repository maintains it? What exact evidence was inspected? Which statement does that evidence support? What remains uncertain? Answer each question in one sentence, then connect every answer to a visible field, file or source page. This review catches common mistakes: citing a collection when a file supplied the value, treating the newest release as the analysed release, confusing permission with scientific suitability, or turning a discovery count into a conclusion. It also gives students a calm way to improve work. A missing detail becomes a next research step instead of an invitation to guess. When the route is complete, the final explanation can stay simple because the identifiers, dates, versions, limitations and supporting evidence are already organised underneath it.
