This second edition cancals and replaces the first edition (1980). Specifies the verification of cylindrical threads, the dimensions and tolerances of which are given in ISO 228-1. Since this 55o profile has different elements to be verified, it is necessary to provide for several GO and several NOT GO gouges.
