ISO 1:2016

ISO 1:2016 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. ISO 1:2016 Standard is also applicable to the definition of the measurand used in verification or calibration.
