scope:

This Technical Report provides guidelines for setting gauging (or test) limits in support of accept/reject decisions in workpiece inspections, instrument verifications, and general conformance tests where uncertain numerical test results are compared with specified requirements.

In accepting or rejecting workpieces or instruments based on the results of inspection measurements, the presence of unavoidable measurement uncertainty introduces the risk of making erroneous decisions. By implementing a decision rule that defines a range of acceptable measurement results, one can balance the risks of rejecting conforming workpieces or instruments and accepting nonconforming ones.
