10、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 organizations, governmental
11、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 the ISO/IEC Directive
12、s, 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 the member bodies c
13、asting 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 8820-6 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee
14、SC 3, Electrical and electronic equipment. ISO 8820 consists of the following parts, under the general title Road vehicles Fuse-links: Part 1: Definitions and general test requirements Part 2: Users guide Part 3: Fuse-links with tabs (blade type) Part 4: Fuse-links with female contacts (type A) and
15、bolt-in contacts (type B) and their test fixtures Part 5: Fuse-links with axial terminals (Strip fuse-links) Types SF 30 and SF 51 and test fixtures Part 6: Single-bolt fuse-links Part 7: Fuse-links with tabs (Type G) with rated voltage of 450 V -,-,- INTERNATIONAL STANDARD ISO 8820-6:2007(E) ISO 20
16、07 All rights reserved 1 Road vehicles Fuse-links Part 6: Single-bolt fuse-links 1 Scope This part of ISO 8820 specifies single-bolt fuse-links in road vehicles. It establishes, for this fuse-link type, the rated current, test procedures, performance requirements and dimensions. This part of ISO 882
17、0 is applicable to fuse-links with a rated voltage of 58 V, a current rating of u 300 A and a breaking capacity of 2 000 A intended for use in road vehicles at a nominal voltage of 12 V, 24 V and/or 42 V. This part of ISO 8820 is intended to be used in conjunction with ISO 8820-1 and with ISO 8820-2
18、. The numbering of its clauses corresponds to that of ISO 8820-1, whose requirements are applicable, except where modified by requirements particular to this part of ISO 8820. 2 Normative references The following referenced documents are indispensable for the application of this document.
