Quick answer: Use an agreed upper and lower limit at each functional position, with a stated measurement method. A band should not hide unacceptable local excursions.
How should a profile band be interpreted?
A sample curve can cross a limit between sparse measured points. Choose sufficient resolution in regions where the profile changes quickly. Separate manufacturing tolerance from instrument uncertainty and make the acceptance rule explicit.
A practical verification method
Inspect the continuous trace or sufficiently spaced measurements for any excursions, retaining the method and uncertainty statement.
| 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 continuous trace or sufficiently spaced measurements for any excursions, retaining the method and uncertainty statement. | 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.
