7、de 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 tha
8、t 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 a
9、ccordance 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 re
10、quires 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
11、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 i
12、s 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order to decide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn.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
13、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again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn.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
14、 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
15、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 assembl
16、y - type 2 Technical Specification iv ISO 2012 All rights reserved ISO/TS 19072-4:2012(E) 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.). T o build the
17、 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
18、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
19、 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 rig
20、ht 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
21、 Standardization (ISO) draws attention to the fact it is claimed that compliance with this document may involve the use of a patent. ISO take no position concerning the evidence, validity and scope of this patent right. The holder of this patent right has assured the ISO that he is willing to negoti
22、ate 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: FCI 145, rue Yves-Le-Coz 78000 Versailles France Attention is dr
23、awn to the possibility that some of the elements of this document may be the subject of patents rights other than those identified above. ISO shall not be held responsible for identifying any or all such patent rights. ISO 2012 All rights reserved v Road vehicles Connection interface for pyrotechnic
24、 devices, two-way and three-way connections Part 4: Pyrotechnic device and harness connector assembly - type 2 1 Scope This Technical Specification defines the general minimum specifications of a type 2 two-way connection interface, linking the pyrotechnic device and harness connector built into a r
25、oad vehicle. A three-way with ground variant of the pyrotechnic device/initiator harness connector assembly is also defined (see Annex A). 2 Normative references The following referenced documents are indispensable for the application of this document.
