Scope and common interpretation errors
For inspection-report communication, not specific regulatory or certification decisions.
Display resolution, recorded digits and measurement capability differ. Rounding an out-of-limit value before comparison can change the decision, especially when methods differ.
Turn the review into recorded checks
| Step | Action and evidence |
|---|---|
| 1 · Keep raw records | Retain readings, instrument and method rather than only rounded values. |
| 2 · Agree decision rules first | Define tolerance boundaries, rounding and uncertainty treatment before inspection. |
| 3 · Review borderline specimens | Use a more suitable method or joint remeasurement if needed, not endless retesting to select a pass. |
A comparison to avoid misinterpretation
A reading near an upper limit calls for method and rule review. Dropping a decimal place does not automatically authorize release.
Frequently asked question
Is one passing reading among repeats enough?
Apply the predefined repeat-measurement rule to all results.
