Summarise this standard

This part of ISO 228 specifies the requirements for thread form, dimensions, tolerances and designation for

fastening pipe threads, thread sizes 1/16 to 6 inclusive. Both internal and external threads are parallel threads,

intended for the mechanical assembly of the component parts of fittings, cocks and valves, accessories, etc.

These threads are not suitable as jointing threads where a pressure-tight joint is made on the thread. If assemblies

with such threads must be made pressure-tight, this should be effected by compressing two tightening surfaces

outside the threads, and by interposing an appropriate seal.

NOTE 1 For pipe threads where pressure-tight joints are made on the threads, see ISO 7-1.

NOTE 2 ISO 228-2 gives details of methods for verification of fastening thread dimensions and form, and recommended

gauging systems.
