21/30423346 DC

This standard 21/30423346 DC BS ISO 26021-1. Road vehicles. End-of-life activation of in-vehicle pyrotechnic devices is classified in these ICS categories:

• 43.040.80 Crash protection and restraint systems

This document is applicable to road vehicles, where the electronic vehicle interface of the diagnostic link connector (DLC) is used to perform an end-of-life activation of in-vehicle pyrotechnical devices. Apart from actual removal, this is the method to assure that no pyrotechnical substances are left in an end-of-life vehicle (ELV). On-board activation is an effective and safe method.

This document describes use cases and specifies technical requirements in order to support the end-of-life activation of in-vehicle pyrotechnical devices via the electronic communication interface. This document references ISO 14229 series unified diagnostic services implemented on diagnostic communication over Controller Area Network (DoCAN) and Internet Protocol (DoIP) along with the required provision of data definitions.

This document specifies:

• terminology;

• definition of end-of-life activation of in-vehicle pyrotechnical devices relevant use cases;

• communication establishment between the PDT and the vehicle's PCU(s);

• optional usage of a credentials-based authentication and authorisation mechanism between the PDT and the vehicle;

• protection against tampering of the defined end-of-life activation of in-vehicle pyrotechnical devices;

• definition of PCU-relevant technical requirements.

PDT-relevant requirements are specified in a test equipment-specific standard with PDT-specifc requirements.
