This Standard 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.
This Standard 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).
This Standard only applies for characteristics and maximum permissible errors expressed as quantity values.
See Annex JA for economically optimal measuring equipment, and decision rules for acceptance and rejection of workpieces.
NOTE 1 Annex JA is prepared based on the following International Standard.
ISO/TR 14253-6:2012 Geometrical product specifications (GPS)—Inspection by measurement of workpieces and measuring equipment—Part 6: Generalized decision rules for the acceptance and rejection of instruments and workpieces
NOTE 2 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.
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 (MOD)
In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
