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

Introduction
This document was prepared following a joint resolution to improve the general structure of the ISO
Automotive Electric Cable standards. This new structure adds more clarity and, by defining a new
standard family, opens up the standard for future amendments.
Many other standards currently refer to ISO 6722-1, ISO 6722-2 and ISO 14572. So these standards
will stay valid at least until the next scheduled systematic review and will be replaced later on by the
ISO 19642 series.
For new Automotive Cable Projects customers and suppliers are advised on using the ISO 19642 series.
