Road vehicles — Fuse-links — Part 8: Fuse-links with bolt-in contacts (Type H and J) with rated voltage of 450 V

ISO 8820-8:2012 specifies fuse-links with bolt-in contacts (Type H and J) and test fixtures for the fuse-links for use in road vehicles. It establishes, for these fuse-link types, the rated current, test procedures, performance requirements and dimensions. ISO 8820-8:2012 is applicable to fuse-links with a rated voltage of 450 V d.c., a current rating of ≤ 400 A and a breaking capacity of 2 000 A intended for use in road vehicles. ISO 8820-8:2012 is intended to be used in conjunction with ISO 8820-1 and with ISO 8820-2. The numbering of its clauses corresponds to that of ISO 8820-1 whose requirements are applicable, except where modified by requirements particular to ISO 8820-8:2012.

Foreword
ISO (the 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
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 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 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
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 8820-8 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee 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: User’s guide
— Part 3: Fuse-links with tabs (blade type) Type C (medium), Type E (high current) and Type F (miniature)
