3. Joint Harmonization Group March 1993 ISO/TC 3 (D)  ISO/TC 10/SC 5 (USSR) (USA) ISO/TC 57

4. ISO TC 213-SCOPE Standardization in the field of geometrical product specifications (GPS) i.e. macro- and microgeometry specifications covering dimensional and geometrical tolerancing, surface properties and the related verification principles, measuring equipment and calibration requirements including the uncertainty of dimensional and geometrical measurements. The standardization includes the basic layout and explanation of drawing indications (symbols). Note: The definition of the specific proportions and dimensions of drawing indications (symbols) and their execution are excluded from the scope.
