scope:

This Standard specifies the general requirements, calibration, terms and definitions of characteristics of GPS measuring equipment, for example micrometers, callipers, gauge blocks and rotary axis form measuring instruments. This Standard forms the basis for standards defining and describing the design characteristics and metrological characteristics for measuring equipment and gives guidance for the development and content of standards for GPS measuring equipment.

This Standard is intended to ease the communication between manufacturer/supplier and user/customer and to make the specification phase of GPS measuring equipment more accurate. This Standard is also intended as a tool to be used in companies in the process of defining and selecting relevant characteristics for measuring equipment.

This Standard includes terms which are frequently used in connection with the characterization of specific measuring equipment.

NOTE The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 14978 : 2018 Geometrical product specifications (GPS) - General concepts and requirements for GPS measuring equipment (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.
