BS EN ISO 228-1:2003 非螺纹密封连接的管螺纹.尺寸规格,公差和名称符号

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.

Pipe threads where pressure-tight joints are not made on the threads - Dimensions, tolerances and designation

BS EN ISO 228-2:2003 非螺纹密封连接的管螺纹.用极限量规检验

This part of IS0 228 specifies the verification, by means of limit gauges, of cylindrical threads, the dimensions and tolerances of which are given in IS0 228-l. For industrial applications (see for example IS0 1179), it may be necessary to carry out additional checks. Since this 55O 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 (see clauses 6 and 7) shall 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-l; b) the threaded NOT GO gauges for the threads of the pieces (see clauses 6 and 7) fix the minimum material limit on the flanks of the thread.

ISO 7-2:2000 用螺纹密封的管螺纹 第2部分:用极限量规检验

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.
