Quick answer: It allows performance differences to be attributed to material, process or geometry instead of mixing those causes.
Why should material lots stay identifiable during prototypes?
A trial built from several unidentified strips can produce a promising result that cannot be repeated. Keep part and lot identities through measurement, including rejected samples. The smallest useful traceability system is one that preserves the variables actually under evaluation.
A practical verification method
Check that every test result can be linked to a part, material lot and build condition.
| 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 | Check that every test result can be linked to a part, material lot and build condition. | 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.
