The work of preparing Intern

13、ational 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

14、 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,

15、Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.

21、s integrate an increasing number of pyrotechnic devices contributing to occupant safety in vehicles (for example, frontal and side air bags, safety belt pretensioner, etc.).To build the complete system providing the function requires a supply of various components from several different equipment ma

22、kers. Vehicle manufacturers need to define a common specification to ensure that connectors designed and produced by the various equipment makers meet the same performance criteria and requirements.In the current design of this vehicle equipment, three areas of connection have been identified: betwe

23、en the pyrotechnic device (e.g. initiator) and the harness connector; between the tab holder and the clip holder of the harness connector; between the harness connector and the electronic control module.The connection between the pyrotechnic device and the harness connector is the only connection th

24、at can be standardized and forms the subject of this part of ISO 19072. Due to the location of the safety device in the vehicle, the connector design could be a right angle or straight.A sealed variant of the pyrotechnic device/initiator harness connector assembly is defined in Annex A.A two-way (wi

25、thout ground) variant of the pyrotechnic device/initiator harness connector assembly is also defined in Annex B.A variant without a retainer of the pyrotechnic device/initiator harness connector assembly is defined in Annex C.

26、vehicles Connection interface for pyrotechnic devices, two-way and three-way connections Part 2: Test methods and general performance requirements1 ScopeThe purpose of this part of ISO 19072 is to define the performance criteria and requirements of a three-way connection interface, including ground

27、connection, linking the pyrotechnic device and harness connector built into a road vehicle.Performance criteria and requirements are also defined for a sealed variant of the pyrotechnic device/initiator harness connector assembly.Performance criteria and requirements are also defined for a two-way (

28、without ground) variant of the pyrotechnic device/initiator harness connector assembly.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
