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
14、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. In
15、ternational 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. Publi

19、Introduction Worldwide, nearly all new vehicles are equipped with one or more safety systems. This can include advanced protection systems based on pyrotechnic actuators. All components which contain pyrotechnic substances can be handled in the same way. Recycling these vehicles demands a new proces
20、s to ensure that the deactivation of airbags is safe and cost-efficient. Due to the harmonization of the on-board diagnostic (OBD) interface, there is a possibility of using it for on-board deployment, which is based on the same tools and processes. Representatives of the global automobile industry
21、agreed that automobile manufacturers do not support reuse as an appropriate treatment method for pyrotechnic devices, believe treatment of pyrotechnic devices is required before shredding, and support in-vehicle deployment as the preferred method. Based on this agreement, the four big associations o
22、f automobile manufacturers (ACEA, Alliance, JAMA and KAMA) started to develop a method for the “in-vehicle deployment of pyrotechnic components in cars with the pyrotechnic device deployment tool (PDT)”. The objective is that in the future a dismantler will use only one tool without any accessories
23、to deploy all pyrotechnic devices inside an end-of-life vehicle (ELV) by using an existing interface to the car. It is necessary to test and to validate the development of the disposal functionality inside the pyrotechnical control unit (PCU). BS ISO 26021-3:2009BS ISO 26021-3:2009INTERNATIONAL STAN
24、DARD ISO 26021-3:2009(E) ISO 2009 All rights reserved 1Road vehicles End-of-life activation of on-board pyrotechnic devices Part 3: Tool requirements 1 Scope This part of ISO 26021 specifies the technical requirements to realize tool requirements for end-of-life activation of on-board pyrotechnic de
25、vices. It defines a test tool for ISO 26021 disposal functionality as well as the requirement for the final pyrotechnical device deployment tool (PDT). The focus is the definition of the human interface and the interfaces to the vehicle. It also defines general requirements for tests to validate the
26、 disposal functionality of the PCU. It specifies two tool use cases. Tool use case 1 deployment test tool (DTT): a development tool used to test and validate the PCU; the target users of this tool are the engineers of the PCU suppliers and the OEMs; the use case defines the human interface, the inte
27、rfaces to the vehicle (CAN the target users of this tool are dismantlers; the use case defines the human interface, the interfaces to the vehicle (CAN Pin 5: signal ground; Pin 6: CAN-H; Pin 14: CAN-L; Pin15: ACL (earlier L-line); Pin 16: permanent positive voltage. It is not necessary to separate t
28、he connector for the 12 V and 24 V system because the 24 V male connector can mate with both 12 V female and 24 V female connectors. The battery voltage value of the PCU provided to the PDT via Pin 16 can dictate the appropriate hardware parameter of the PDT. BS ISO 26021-3:2009ISO 26021-3:2009(E) I
