The work of preparing International Standards is normally carried
14、 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
15、 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
16、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
17、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 9654 was prepared by Technical Committee ISO/TC 29, Small tools, Subcommittee SC 10, Assembly tools for screws and nuts, pliers and nippers. This second edi
18、tion cancels and replaces the first edition (ISO 9654:1989) which has been technically revised.

19、 Standard specifies the principal dimensions of single-purpose cutting nippers for electronics and the range of diameters of test wires to be used to verify the functional performance of these nippers in accordance with ISO 9656. The general technical requirements are given in ISO 9657. The cutting
20、nippers illustrated in this International Standard are only examples and are not intended to affect the manufacturers design. 2 Normative references The following referenced documents are indispensable for the application of this document.
