适用范围：This part of IS0 228 specifies the verification, by means of limitgauges, of cylindrical threads, the dimensions and tolerancesof which are given in IS0 228-l.For industrial applications (see for example IS0 1179), it may benecessary to carry out additional checks.Since this 55O profile has different elements to be verified, it isnecessary to provide for several GO and several NOT GOgauges :a) the threaded GO gauges (see clauses 6 and 7) shall ensurethat the profile of the machined piece does not exceedthe maximum of material provided for by the tolerances appliedto the dimensions of the profile defined by IS0 228-l;b) the threaded NOT GO gauges for the threads of thepieces (see clauses 6 and 7) fix the minimum material limiton the flanks of the thread.
