Road vehicles — Fuse-links — Part 11: Fuse-links with tabs (blade type) Type M (medium-high current)

This document specifies fuse-links with tabs (blade-type) Type M (medium-high current) for use in road vehicles. It establishes, for this fuse-link type, the rated current, test procedures, performance requirements and dimensions. This document is applicable for fuse-links with a rated voltage of 32 V and a current rating of ≤80 A and a breaking capacity of 1 000 A intended for use in road vehicles. This document is intended to be used in conjunction with ISO 8820‑1 and ISO 8820‑2. The numbering of the clauses corresponds to that of ISO 8820‑1 whose requirements are applicable, except where modified by requirements particular to this document.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
