Quick answer: It may retain moisture or residue differently from exposed surfaces, creating a localized environment.
Why should the contact area be examined separately?
A visible clean outer strip does not describe the concealed contact zone. Record both materials and any cleaning or lubricant residue. The corrective action may involve drainage, contact geometry or compatibility rather than a spring-material change alone.
A practical verification method
Inspect the contact pair and evaluate the relevant exposure with the actual assembly materials.
| 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 | Inspect the contact pair and evaluate the relevant exposure with the actual assembly materials. | 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.
