11、ldwide 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
12、 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. The procedures used to develop this
13、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 noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Dire
14、ctives, 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 identifying any or all such patent rights. Details of any patent rights identified during the devel

It does not specify any crash test procedure. The safety requirements of this part of ISO 6469 apply to applicable vehicles in accorda
21、nce with published crash test procedures of each country or region. Applicable vehicles are those vehicles which are explicitly specified in these crash test procedures. It does not provide comprehensive safety information for first responders, emergency services, maintenance, and repair personnel.

34、pplied crash test procedures The safety requirements of this part of ISO 6469 shall apply in accordance with the published crash test procedures of a country or region for vehicles or test configurations which are explicitly specified in these crash test procedures. 5 Electric safety requirements 5.
35、1 General The following requirements shall be fulfilled after a vehicle crash test or after a crash test with a test configuration according to 4. NOTE Retention of voltage class B components, e.g. RESS, is not covered in this part of ISO 6469 because it is not relevant for electrical safety. 5.2 Pr
36、otection against electric shock 5.2.1 General After the crash test at least one of the criteria specified in 5.2.2 through 5.2.5 shall be met for each voltage class B electric circuit. This includes all voltage class B electric circuits which are disconnected or electrically separated in post-crash
37、situations. For different parts of a circuit, different criteria specified in 5.2.2 through 5.2.5 may apply. If the test is performed under the condition that part(s) of the voltage class B electric circuits are not electrically energized because of specific crash test conditions different from norm
38、al operation, the protection against electric shock shall be proved by either 5.2.3 or 5.2.4 for the relevant part(s). Examples for such specific test conditions are as follows: fuel cell vehicle crash test performed with alternative fuel; crash test performed with energy sources disconnected prior
39、to the crash test. NOTE Electronic switches can be used for disconnection. ISO 2015 All rights reserved 3BS ISO 6469-4:2015ISO 6469-4:2015(E) 5.2.2 Voltage limit The voltages V b , V 1 , and V 2(see Figure 1) of the voltage class B electric circuits shall be equal to or less than 30 V a.c. (rms) or
40、60 V d.c. at a point in time t mwhich is specified as either 10 s after the initial impact, if the vehicle comes to rest within 5 s after the initial impact, or 5 s after the vehicle comes to rest, if the vehicle does not come to rest within 5 s after the initial impact. Compliance shall be tested i
41、n accordance with 7.2.2. 5.2.3 Isolation resistance 5.2.3.1 General The isolation resistance shall fulfil the requirements according to 5.2.3.2 and 5.2.3.3. If direct contact to one potential of the voltage class B electric circuit is possible, the energy in Y-capacitors, TE y , as calculated in 7.2
42、.5.2.2 shall be less than 0,2 J. NOTE A potential body current caused by Y-capacitors is not limited by isolation resistance. The isolation resistance criterion shall not apply if direct contact to more than one single potential of a part of the voltage class B electric circuit is possible; see 5.2.
43、4 (physical protection). However, isolation resistance criterion is applicable if the voltage difference between those accessible live parts meets the voltage limit specified in 5.2.2 or the potential energy between them meets the energy limit specified in 5.2.5. Compliance shall be tested in accord
44、ance with 7.2.3. If test procedures include a static rollover test after a crash, evaluation of isolation resistance can be conducted before, during, and/or after the rollover test. 5.2.3.2 Separated d.c. and a.c. voltage class B electric circuits If the a.c. voltage class B electric circuits and th
