16、 International Organization for Standardization) is a worldwide federation 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 committe
17、e 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 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechni
18、cal 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 International Standards. Draft International Standards adopted by the technical committees are circulated to the member b
19、odies 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 elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying a
20、ny or all such patent rights. ISO 5821 was prepared by Technical Committee ISO/TC 44, Welding and 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. Requ
21、ests for official interpretations of any aspect of this International Standard should be directed to the Secretariat of ISO/TC 44/SC 6 via your national standards body, a complete listing of which can be found at www.iso.org.

23、ional 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 diamete

42、 classification according to Table 1 is mainly based on the previous edition of this International Standard. The classification according to Annex A is mainly based on standards specifying taper 1:9,6. Application of either type of classification designation identifies a product as classified accord
43、ing 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. Although it is recognised that the 1:10 taper is not universally used currently, it is felt that a move to a 1:10
44、 taper would be in the interest of global relevance and therefore it is intended to delete this annex in a future revision. A.2 Types and dimensions Table A.1 and Figure A.1 show alternative types of female electrode caps; the corresponding symbols between Table 1 and Figure 1 and this annex are in
