Quick answer: Review retention, functional datum, local contact and relevant duty checks for the revised interface.
Which tests need review after an attachment changes?
The rest of the spring may be unchanged, but the attachment determines how load enters it. A dimensional approval alone may not address fatigue or slip at that interface. Use the actual mating geometry and identify the revision in every sample record.
A practical verification method
Compare engagement and measured function, then repeat the interface-related validation required by the change review.
| 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 engagement and measured function, then repeat the interface-related validation required by the change review. | 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.
