8、ation of national 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 commit
9、tee. International 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. International Standards are drafted in accordanc
10、e with the rules given in the ISO/IEC Directives, Part 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 a
11、pproval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 1641-2 was prepared by Technical Co
12、mmittee ISO/TC 29, Small tools, Subcommittee SC 2, High speed steel cutting tools and their attachments. This second edition cancels and replaces the first edition (ISO 1641-2:1978), of which it constitutes a minor revision. In particular, this includes updating of the normative references, addition
13、 of the designation (see Clause 4) and indication of the tolerance classes in accordance with ISO 2768-1 and ISO 2768-2. ISO 1641 consists of the following parts, under the general title End mills and slot drills: Part 1: Milling cutters with cylindrical shanks Part 2: Dimensions and designation of
