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
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso

This document was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 32,
Electrical and electronic components and general system aspects.
This third edition cancels and replaces the second edition (ISO 19072-1:2014), which has been
technically revised.
The main changes compared to the previous edition are as follows:
— greater detail has been specified in 5.2 regarding the contacts and short circuit areas for the male
contacts;
— Annex C has been added to define an alternative material variant of the pyrotechnic device/initiator
harness connector assembly.
A list of all parts in the ISO 19072 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
Road vehicles integrate an increasing number of pyrotechnic devices contributing to occupant safety in
vehicles (for example, frontal and side air bag, safety belt pretensioner, etc.).
Various pocket definitions currently exist all over the world. This situation appears difficult to manage
for the different equipment makers. The goal of this document is to define a common specification.
A sealed option of the pyrotechnic device/initiator harness connector assembly is defined in Annex A.
A variant without retainer of the pyrotechnic device/initiator harness connector assembly is defined in
Annex B.
An alternative material variant of the pyrotechnic device/initiator harness connector assembly is
defined in Annex C.
