ISO 8820-5:2007

Road vehicles — Fuse-links — Part 5: Fuse-links with axial terminals (Strip fuse-links) Types SF 30 and SF 51 and test fixtures

ISO 8820-5:2007 specifies fuse-links with axial terminals (Strip fuse-links) Type SF30 and SF51 and test fixtures for fuses in road vehicles. It establishes, for these fuse-link types, the rated current, test procedures, performance requirements and dimensions. ISO 8820-5:2007 is applicable to fuse-links with a rated voltage of 32 V, a current rating of 30 A to 500 A and a breaking capacity of 2000 A intended for use in the electrical system of road vehicles with a nominal voltage of 12 V and/or 24 V. ISO 8820-5:2007 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 8820-5:2007.

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 8820-5 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

1 Scope
This part of ISO 8820 specifies fuse-links with axial terminals (Strip fuse-links) Type SF 30 and SF 51 and test
fixtures for fuses in road vehicles. It establishes, for these fuse-link types, the rated current, test procedures,
performance requirements and dimensions.
This part of ISO 8820 is applicable to fuse-links with a rated voltage of 32 V, a current rating of 30 A to 500 A
and a breaking capacity of 2 000 A intended for use in the electrical system of road vehicles with a nominal
voltage of 12 V and/or 24 V.
This part of ISO 8820 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 this part of ISO 8820.
