If: ( \textLSL < \textmeasured value - U ) and ( \textmeasured value + U > \textLSL ) (or similar near USL) → without additional information or reduced uncertainty.

The core philosophy of ISO 14253-1 is simple: You must compare the specification limit minus the measurement uncertainty. INTERNATIONAL STANDARD ISO 14253 1.pdf

If the measured value falls into an indeterminate zone, the standard says unless a different agreement is made (e.g., reduced uncertainty or re‑measurement with a better instrument). If: ( \textLSL &lt; \textmeasured value - U

It is applicable whenever the tolerance limits are specified as (meaning the specification applies to the actual value of the characteristic, not just the measured value).
