Spring Long-Dwell Test with Restart Inspection

Quick answer: Inspect the first restart, subsequent motion and relevant contact condition after the defined held state.

What should a long-dwell test include besides final output?

A repeated sweep after dwell can erase the initial sticking behavior. Record the first movement separately. State position, environment and duration so the trial corresponds to a real use case instead of an undefined storage test.

A practical verification method

Capture first-restart force and motion, then compare the following trace with the pre-dwell baseline.

Original verification plan for this specific decision. Acceptance values must be agreed for the actual product.

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.
