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

Introduction
Road vehicles integrate an increasing number of pyrotechnic devices contributing to occupant safety in
vehicles (for example frontal and side airbag, safety belt pre-tensioner, etc.).
Building the complete system requires a supply of various components from several different equipment
suppliers. There is a need for vehicle manufacturers to define a common specification to ensure that
connectors designed and produced for the various equipment suppliers can be mated without any
difficulty.
In the current design of this vehicle equipment, three areas of connection have been identified:
— connection between the pyrotechnic device (e.g. initiator) and the harness connector;
— connection between the tab holder and the clip holder of the harness connector; and
— connection between the harness connector and the electronic control module.
The connection between the pyrotechnic device and the harness connector is the only connection that
can be standardised, and it forms the subject of this document. Due to the location of the safety device
in the vehicle, the connector design could be right angle or straight.
