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three years, revised to become an International Standard, or withdrawn.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Standard or be withdrawn.
ISO/TS 19072-3 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3,
Electrical and electronic equipment.
This second edition cancels and replaces the first edition (ISO/TS 19072-3:2008), which has been technically revised.
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 performance requirements
— Part 3: Pyrotechnic device and harness connector assembly - type 1 [Technical Specification]
The following parts are under preparation:
— 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,
e.g. frontal and side air bag, safety belt pretensioner.
To build the complete system providing the function requires a supply of various components from several
different equipment makers. Vehicle manufacturers need to define a common specification to ensure that
connectors designed and produced for the various equipment makers 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
standardized 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 two-way without ground option of the pyrotechnic device/initiator and harness connector
assembly is also defined.
The International Organization for Standardization (ISO) draws attention to the fact that it is claimed that
compliance with this document may involve the use of a patent.
ISO takes no position concerning the evidence, validity or scope of this patent right.
The holder of this patent right has assured ISO that he is willing to negotiate licences under reasonable and
non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of
the holder of this patent right is registered with ISO. Information may be obtained from:

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights
other than those identified above. ISO shall not be held responsible for identifying any or all such patent rights.

TECHNICAL SPECIFICATION ISO/TS 19072-3:2012(E)
Road vehicles — Connection interface for pyrotechnic devices,
two-way and three-way connections —
Part 3:
Pyrotechnic device and harness connector assembly - type 1
1 Scope
This Technical Specification defines the general minimum specifications of a type 1 three-way connection interface,
including ground connection, linking the pyrotechnic device and harness connector built into a road vehicle.
A two-way without ground variant of the pyrotechnic device/initiator and harness connector assembly is also
defined. All requirements apply also to t
