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.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of document:
— an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical
experts in an ISO working group and is accepted for publication if it is approved by more than 50 %
of the members of the parent committee casting a vote;
— an ISO Technical Specification (ISO/TS) represents an agreement between the members of a
technical committee and is accepted for publication if it is approved by 2/3 of the members of the
committee casting a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for
a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or
ISO/TS is confirmed, it is reviewed again after a further three years, at which time it must either be
transformed into an International Standard or be withdrawn.
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/TS 19072-4 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3,
Electrical and electronic equipment.
ISO 19072 consists of the following parts, under the general title Road vehicles — Connection interface for
pyrotechnic devices, two-way and three-way connections:
— Part 1: Pocket interface definition
— Part 2: Test methods and general performances requirements
— Part 3: Pyrotechnic device and harness connector assembly – type 1 [Technical Specification]
— Part 4: Pyrotechnic device and harness connector assembly - type 2 [Technical Specification]

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.).
To build the complete system requires a requires a supply of various components from several different
equipment suppliers. Vehicle manufacturers need 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;
— 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 Technical Specification. Due to the location of the
safety device in the vehicle, the connector design could be right angle or straight.
Due to the fact that several electrostatic discharge (ESD) protection levels are requested by vehicle
manufacturers, a three-way or a two-way without ground option of the pyrotechnic device/initiator
harness connector assembly is also defined.
The International Organization for Standardization (ISO) draws attention to the fact it is claimed that
