scope:

This Technical Report establishes guidelines for verifying geometrical tolerancing as described in ISO 1101. The purpose is to outline the fundamentals of various verification principles which may be used in order to comply with the definitions of ISO 1101. The verification methods described in this Technical Report do not provide for a unique interpretation of the requirements of ISO 1101 and do differ amongst themselves. This Technical Report may, however, be used as a reference document for coordination and agreements in the field of geometrical tolerancing verification. The symbology and methods are not illustrated in detail and are not intended for application on end-product drawings. Not all verification principles are given in this Technical Report for the different types of geometrical tolerances. Within the verification principle one or more verification methods are used. The numbering of verification principles and methods shall not be regarded as a classification within the prescribed type of geometrical tolerance.
