16、es). 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 organizations, governmental and
17、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 the ISO/IEC Directives, P
18、art 3. 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 elements of
19、 this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 5828 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 6, Resistance welding. This
20、second edition cancels and replaces the first edition (ISO 5828:1983) which has been technically revised. In particular it has been extended to take in lowly flexible cables with requirements for type LF cables given in clause 6. The values of the chemical composition and electrical properties are i
21、dentical to those of Cu-ETP and Cu-FRHC, defined in ISO 1337:1980 which has been withdrawn.This standard may only be used and printed by approved subscription and freemailing clients of the SABS.

23、cting cables which are air- cooled over their length and with terminals connected to water-cooled lugs. The secondary connecting cables are used for connection between the secondary terminals of a welding transformer and the electrode holders. 2 Classification The secondary connecting cables are cla
24、ssified into low flexibility (LF), flexible (F) and highly flexible types (HF) depending on diameter of wire (see clause 6). 3 Dimensions The dimensions of the secondary connecting cables shall be as given in Figure 1 and Table 1.
