The work of preparing International Standards is normally carried out through IS0 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. International organizations, govern- mental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Inter- national Standard requires approval by at least 75% of the member bodies casting a vote. International Standard IS0 529 was prepared by Technical Committee ISO/TC 29, Small tools, Sub-Committee SC 4, Screwing taps and dies. This second edition cancels and replaces the first edition (IS0 529:1975), of which it constitutes a technical revision. Annex A forms an integral part of this International Standard. Annexes B and C are for information only. iv COPYRIGHT International Organization for Standardization Licensed by Information Handling Services COPYRIGHT International Organization for Standardization Licensed by Information Handling Services IS0 529 93 m 4851903 0527185 851 m I b) IS0 inch threads - “ U n ifi e d Coarse ” se ri e s (U NC) and “ U n ifi e d F in e ” se r ies (U N F). INTERNATIONAL STANDARD IS0 5291993(E) Short machine taps and hand taps Section I: General 1.1 Scope This International Standard specifies the general dimensions of short machine taps and hand taps. These di- mensions, 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 International Standard is applicable to taps intended for cutting the following threads: a) IS0 metric threads - coarse pitch: - fine pitch. c) Inch threads, non-recommended - “British Standard Whitworth” (BSW) and “British Standard Fine” (BSF); - “British Association” (BA). NOTES I tables are given in table A.I. 2 Annex B gives an abstract from IS0 237 for shank diameters and size of driving squares, for information. The overall length, thread length and diameters of shank for taps whose thread diameter and pitch are not listed in Technical specifications for taps covered by this International Standard (including marking) are given in IS0 8830. 1.2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.
