scope:

This part of ISO 14253 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 given maximum permissible errors for a metrological characteristic of a measuring equipment, including when the measurement result falls close to the specification limits, taking measurement uncertainty into account. This part of ISO 14253 applies to specifications defined in general GPS standards (see ISO 14638), i.e. standards prepared by ISO/TC 213, including: - workpiece/population of workpieces specifications (usually given as an upper specification limit or a lower specification limit or both), and; - measuring equipment specifications (usually given as maximum permissible errors). This part of ISO 14253 only applies for characteristics and maximum permissible errors expressed as quantity values.
