The work of preparing International Standards is normally carried

8、 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 non-governmental, in liaison with ISO, also take part in the work. ISO

9、 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, Part 2. The main task of technical committees is to prepare Internation

10、al 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 a vote. Attention is drawn to the possibility that some of the elem

11、ents 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 3860 was prepared by Technical Committee ISO/TC 29, Small tools, Subcommittee SC 2, High speed steel cutting tools and their attachments. This second editio
