ISO/TC 213

Dimensional and geometrical product specifications and

verification

ISO/TC 57

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.

ISO/TC 213 - Main Goals

1. To reduce the Correlation Uncertaintya) Develop the necessary functional related tool

2. To reduce the Specification Uncertaintya) Defining operators

b) Develop clear and unambiguous rules

c) Stating default rules

3. To enrich the improved GPS-Languagea) Strive to keep it as simple as possible
