Quick answer: State how many identified samples were tested, how they were selected and which batches or conditions they represent.

What should sample size communicate?
A small prototype study can guide design without establishing population reliability. Avoid expressing a broad performance guarantee from one successful part. The sampling plan should match the decision being made and applicable requirements.

A practical verification method
Check that conclusions do not extend beyond the tested population and recorded conditions.
| Item | What to record | Purpose |
|---|---|---|
| Reference configuration | Part or assembly identity and drawing revision | Make comparisons traceable |
| Test conditions | Relevant position, direction and operating condition | Compare the same characteristic |
| Decision evidence | Check that conclusions do not extend beyond the tested population and recorded conditions. | Resolve the specific question before approval |

Use the result in an engineering request
Describe the observed condition and the required function separately. Include the relevant drawing revision and your results from the check above. If an acceptance limit has not been established, identify it as an open design input rather than treating a successful trial as approval.
