Quick answer: Track reference measurements and inspect contact or alignment features that influence the result.

How can fixture degradation be detected?
A slowly changing fixture can create an apparent batch trend. Define a relevant check interval and a response to reference drift. A calibrated sensor does not prove the mechanical fixture remains unchanged.

A practical verification method
Compare an identified reference condition over time and inspect fixture geometry when the result shifts.
| 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 an identified reference condition over time and inspect fixture geometry when the result shifts. | 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.
