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 14572 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical
and electronic equipment.
This third edition cancels and replaces the second edition (ISO 14572:2006), which has been technically revised.

WARNING — The use of this International Standard may involve hazardous materials, operations, and
equipment. This International Standard does not purport to address all of the safety concerns, if any,
associated with its use. It is the responsibility of the user of this International Standard to establish
appropriate safety practices and determine the applicability of regulatory limitations prior to use.
1 Scope
This International Standard specifies test methods and requirements for basic- and high-performance round,
single- or multi-core sheathed cables intended for use in road vehicle applications where the nominal system
voltage is ≤ (60 V d.c. or 25 V a.c.). It also specifies additional test methods and/or requirements for 600 V
cables intended for use in road vehicle applications where the nominal system voltage is > (60 V d.c. or
