Quick answer: A controlled batch identity and applicable process revision must connect the treatment run to the parts tested.

What should link a treatment record to finished parts?
A temperature record from a similar run is not evidence for the actual batch. Material condition and treatment purpose differ by design, so avoid assuming one schedule applies to every strip spring. Document the approved route and preserve disposition of abnormal runs.

A practical verification method
Trace selected finished parts to the relevant run and compare its record with the approved process specification.
| 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 | Trace selected finished parts to the relevant run and compare its record with the approved process specification. | 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.
