Pipe threads where pressure-tight joints are not made on the threads – Part 2: Verification by means of limit gauges

Executive summary

Requirements for the verification of cylindrical threads by means of limit gauges.

Abstract

This International Standard, a part of the IS0 228 series, specifies the verification, by means of limit gauges, of cylindrical threads, the dimensions and tolerances of which are given in IS0 228-1.

For industrial applications, it may be necessary to carry out additional checks.

Since this 55 degree profile has different elements to be verified, it is necessary to provide for several GO and several NOT GO gauges:

a) the threaded GO gauges ensure that the profile of the machined piece does not exceed the maximum of material provided for by the tolerances applied to the dimensions of the profile defined by IS0 228-1;

b) the threaded NOT GO gauges for the threads of the pieces fix the minimum material limit on the flanks of the thread.

History and related standards

This International Standard together with BS EN ISO 228-1:2003 supersedes BS 2779:1986 which is withdrawn.

It includes the following cross references:

IS0 228-1, IS0 1179, IS0 1502.
