10、ISO 19072-1:2014(E)ForewordISO (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 sub
11、ject 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 (I
12、EC) 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
13、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 identify
14、ing 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 convenienc
15、e of users and does not constitute an endorsement.For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISOs adherence to the WTO principles in the Technical Barriers to Trade (TBT) see the following URL: Foreword - Sup

17、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 Part 4: Pyrot

19、etensioner, 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 International Standard is to define a common specification.A sealed option of the pyrotechnic device/initiator harness conn
20、ector assembly is also defined. See Annex A.A variant without retainer of the pyrotechnic device/initiator harness connector assembly is also defined. See Annex B.The International Organization for Standardization (ISO) draws attention to the fact that it is claimed that compliance with this documen
21、t may involve the use of a patents DE19939407, EP-B-1079474 and US-A-6,402,640.ISO takes no position concerning the evidence, validity and scope of this patent right.The holder of this patent right has assured ISO that he/she is willing to negotiate licences either free of charge or under reasonable
22、 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.
