21/30433772 DC

This standard 21/30433772 DC BS EN ISO 1. Geometrical product specifications (GPS). Standard reference temperature for the specification of geometrical and dimensional properties is classified in these ICS categories:

• 17.040.01 Linear and angular measurements in general

This document defines the concepts of a reference temperature and of the standard reference temperature, and specifies the standard reference temperature value for the specification of geometrical and dimensional properties of an object. Some examples of geometrical and dimensional properties include size, location, orientation (including angle), form and surface texture of a workpiece.

This document is also applicable to the definition of the measurand used in verification or calibration.
