Quick answer: Relate it to the questions being investigated, build variants and destructive or durability checks.
How should prototype quantity be chosen?
A single assembly-fit sample cannot also serve every life-test and material-investigation purpose. Keep sample identities and allocation visible. Ask which tests consume or alter a sample so later acceptance does not rely on a previously damaged part.
A practical verification method
Create a sample-use plan showing variant, test purpose and final disposition for each identified part.
| 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 | Create a sample-use plan showing variant, test purpose and final disposition for each identified part. | 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.
