Quick answer: Review changes that can affect material condition, dimensions, surface contact, attachments or measured output.
Which changes should trigger qualification review?
A new machine or route may be equivalent, but that requires evidence. Define a comparison using representative parts and controlled measurement conditions. Keep customer-specific requirements visible when deciding what checks must repeat.
A practical verification method
Compare the changed process with the approved baseline and document the acceptance basis before production release.
| 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 the changed process with the approved baseline and document the acceptance basis before production release. | 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.
