ISO 14253-1:2017

Geometrical product specifications (GPS) — Inspection by measurement of workpieces and measuring equipment — Part 1: Decision rules for verifying conformity or nonconformity with specifications

ISO 14253-1:2017 establishes the rules for verifying the conformity or nonconformity with a given tolerance for a characteristic of a workpiece (or a population of workpieces) or with a given maximum permissible errors for a metrological characteristic of a measuring equipment, including when the measured value falls close to the specification limits, taking measurement uncertainty into account.

ISO 14253-1:2017 applies to specifications defined in general GPS standards (see ISO 14638), i.e. standards prepared by ISO/TC 213, including:

- workpiece specifications and population specifications (usually given as an upper specification limit or a lower specification limit or both);

- measuring equipment specifications (usually given as maximum permissible errors).

ISO 14253-1:2017 only applies for characteristics and maximum permissible errors expressed as quantity values.
