8、es). 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. International organizations, governmental and
9、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.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Pa
10、rt 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting
11、 a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

It does not deal with the knurling tools; these are outside the scope of I
13、SO/TC 10.This International Standard includes dimensional relations for straight and diamond knurling on cylindrical surfaces having teeth of uniform pitch parallel to the axis of the cylinder or at a helix angle of 30 with the axis of work.The knurling is made by displacement of the material on the
14、 surface of a workpiece when rotated under pressure against a knurling tool.The recommendations given are applicable for general purposes. They are intended to improve the uniformity and appearance of knurling, reduce the production of defective work, as well as decrease the number of tools required
15、.In Annex A, an alternative method of dimensioning and indication of knurling is presented. This method uses a module for the calculation of the knurling. Note that this method requires different knurling tools than those used in the method presented in the main body of this International Standard.i
