Appendix 2;

           (b) All protection devices, which would affect the function of the Tested-Device and which are relevant to the outcome of the test shall be operational.

       3.2. Test procedure

       The Tested-Device shall be stored for at least six hours at a test temperature equal to 60 ± 2 °C or higher if requested by the manufacturer, followed by storage for at least six hours at a test temperature equal to -40 ± 2 °C or lower if requested by the manufacturer. The maximum time interval between test temperature extremes shall be 30 minutes. This procedure shall be repeated until a minimum of 5 total cycles are completed, after which the Tested-Device shall be stored for 24 hours at an ambient temperature of 22 ± 5 °C.

       After the storage for 24 hours, a standard cycle as described in Annex 9, Appendix 1 shall be conducted, if not inhibited by the Tested-Device.

       The test shall end with an observation period of 1 h at the ambient temperature conditions of the test environment.

Annex 9C

Mechanical shock

       1. Purpose

       The purpose of this test is to verify the safety performance of the REESS under inertial loads which may occur during a vehicle crash.

       2. Installation

       2.1. This test shall be conducted either with the complete REESS or with REESS subsystem(s). If the manufacturer chooses to test with REESS subsystem(s), the manufacturer shall demonstrate that the test result can reasonably represent the performance of the complete REESS with respect to its safety performance under the same conditions. If the electronic management unit for the REESS is not integrated in the casing enclosing the cells, then the electronic management unit may be omitted from installation on the Tested-Device if so requested by the manufacturer

       2.2. The Tested-Device shall be connected to the test fixture only by the intended mountings provided for the purpose of attaching the REESS or REESS subsystem to the vehicle.

       3. Procedures

       3.1. General test conditions and requirements

       The following condition shall apply to the test:

           (a) The test shall be conducted at an ambient temperature of 20 ± 10 °C,

           (b) At the beginning of the test, the SOC shall be adjusted in accordance with Annex 9, Appendix 2;

           (c) At the beginning of the test, all protection devices which affect the function of the Tested-Device and which are relevant to the outcome of the test, shall be operational.

       3.2. Test procedure

       The Tested-Device shall be decelerated or accelerated in compliance with the acceleration corridors which are specified in Tables 1 to 3. The manufacturer shall decide whether the tests shall be conducted in either the positive or negative direction or both.

       For each of the test pulses specified,
