Quick answer: Preserve part identity, material and process traceability, installed orientation and the observed failure location.
What must be retained before investigating a failed spring?
A cleaned unidentified fragment offers limited evidence. Record the assembly state and duty history without assuming a cause. Separate observed facts from hypotheses so each proposed mechanism can be checked rather than becoming the final conclusion prematurely.
A practical verification method
Build an evidence list that links photographs, fragments and records to the same failed part and assembly.
| 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 | Build an evidence list that links photographs, fragments and records to the same failed part and assembly. | 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.
