13、ational standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Inter
14、national organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those inte
15、nded for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www

These dime
21、nsions, established as functions of the thread diameter and pitch, are the following: length of thread (maximum); overall length; shank diameter and dimensions of driving square; dimensions of the connecting portion between the shank and threaded part.This document is applicable to taps intended for
22、 cutting the following threads:a) ISO metric threads: coarse pitch; fine pitch;b) ISO inch threads: “Unified Coarse” series (UNC) and “Unified Fine” series (UNF);c) Inch threads, non-recommended: “British Standard Whitworth” (BSW) and “British Standard Fine” (BSF); “British Association” (BA).NOTE 1
23、The overall length, thread length and diameters of shank for taps whose thread diameter and pitch are not listed in tables are given in Table A.1.NOTE 2 Annex B gives an abstract from ISO 237 for shank diameters and size of driving squares, for information.NOTE 3 Technical specifications for taps co
