Pipe threads where pressure-tight joints are not made on the threads — Part 2: Verification by means of limit gauges 未在螺纹Spart 2上进行压力密封接头的管螺纹:通过极限量规进行验证

发布日期： 1987-08-20

第二版将取代第一版（1980年）。规定了圆柱螺纹的验证，其尺寸和公差见ISO 228-1。由于55o剖面具有不同的待验证元素，因此有必要提供几个通孔和几个不通孔凿孔。

This second edition cancals and replaces the first edition (1980). Specifies the verification of cylindrical threads, the dimensions and tolerances of which are given in ISO 228-1. Since this 55o profile has different elements to be verified, it is necessary to provide for several GO and several NOT GO gouges.
