This British Standard specifies limits of sizes, and tolerances, for single start parallel screw threads of British Association (B.A.) form. It is not applicable to screw threads associated with interference fits, such as those on the “metal ends” of studs and in the corresponding tapped holes. This British Standard specifies the following: a) basic sizes for B.A. threads, sizes 0 B.A. to 16 B.A.; b) limits of size, and tolerances, for close class and normal class external threads of sizes 0 B.A. to 10 B.A.; c) limits of size, and tolerances, for normal class external threads of sizes 11 B.A. to 16 B.A.; d) limits of size, and tolerances, for a single class of internal threads of sizes 0 B.A. to 16 B.A.

This part of ISO 7 specifies a process using limit gauges, for the validation of taper internal and external threads and parallel internal threads on piping systems components and other products, the dimensions and tolerances of which are detailed in ISO 7-1. The gauging system described may not be suitable, without special precautions, for gauging of threads on injection moulded plastic workpieces. This part of ISO 7 does not cover completely all the requirements necessary for full control of thread quality and dimensions. Additional control of tools and equipment and visual inspection during production are required to ensure complete compliance with ISO 7-1, for example the length of useful thread on internally threaded workpieces should be checked by direct measurement. Annex A gives a summary of the gauges included in this part of ISO 7, together with details of the thread elements controlled by each gauge and gauge identification numbers. In the event of a dispute over compliance with the requirements of ISO 7-1, the gauges in this part of ISO 7 are to be considered as decisive for the thread elements which they control on the workpiece

This part of IS0 7 specifies the requirements for thread form, dimensions, tolerances and designation for jointing pipe threads, sizes 1 /I6 to 6 inclusive, for joints made pressure-tight by the mating of the threads. These threads are taper external, parallel internal or taper internal and are intended for use with pipes suitable for threading and for valves, fittings or other pipeline equipment interconnected by threaded joints.

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.
