15、 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 committee. International organiza
16、tions, 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 accordance with the rules given in t
17、he 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 approval by at least 75 % of
18、 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 5821 was prepared by Technical Committee ISO/TC 44, Welding an
19、d allied processes, Subcommittee SC 6, Resistance welding and allied mechanical joining. This second edition cancels and replaces the first edition (ISO 5821:1979) which has been technically revised. Requests for official interpretations of any aspect of this International Standard should be directe

21、ternational Standard specifies the dimensions and tolerances of resistance spot welding electrode caps, where a female taper (see ISO 1089) is used to fix the cap to an electrode adaptor (see ISO 5183-1 and ISO 5183-2). It applies only to electrode caps for which the electrode force, FE, given for d

The classification according to Annex A is mainly based on standards specifying
39、taper 1:9,6. Application of either type of classification designation identifies a product as classified according to this International Standard. Annex A has been incorporated to improve the market relevance of this International Standard, especially in countries where taper 1:9,6 is still used. Al
40、though it is recognised that the 1:10 taper is not universally used currently, it is felt that a move to a 1:10 taper would be in the interest of global relevance and therefore it is intended to delete this annex in a future revision.
