ISO 8820-7:2007

Road vehicles — Fuse-links — Part 7: Fuse-links with tabs (Type G) with rated voltage of 450 V

ISO 8820-7:2007 specifies fuse-links with tabs (Type G) in road vehicles. This type of fuse-link is basically designed for use in fuel-cell applications. ISO 8820-7:2007 establishes, for this fuse-link type, the rated current, test procedures, performance requirements and dimensions. ISO 8820-7:2007 is applicable for fuse-links with a rated voltage of 450 V, a current rating of up to 70 A and a breaking capacity of 2 000 A intended for use in road vehicles at a nominal voltage up to 450 V.

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 8820-7 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)
⎯ Part 4: Fuse-links with female contacts (type A) and 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
