Quick answer: Specify the allowable transition position as well as force limits. Correct endpoints do not prove correct timing.
What tolerance matters where the curve changes behavior?
A transition that occurs too early can increase effort before a latch or linkage is ready. One that occurs too late may fail to provide the intended final load. Reference the transition to the assembly's functional datum and include the mounting tolerance stack.
A practical verification method
Measure transition location in multiple assemblies and compare it with the mechanism's required event position.
| 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 | Measure transition location in multiple assemblies and compare it with the mechanism's required event position. | 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.
