Quick answer: Use the same drawing revision, functional specification and sample configuration throughout the exchange.
What should link a quote to a sample request?
An old image in an email can contradict the attached drawing. Identify which document controls and preserve accepted deviations. A prototype built to a different revision should be labeled accordingly, so its result is not used to approve the requested production design.
A practical verification method
Compare quote, drawing and sample identification before testing or approving production.
| 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 | Compare quote, drawing and sample identification before testing or approving production. | 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.
