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. Where the relevant REESS subsystems are distributed throughout the vehicle, the test may be conducted on each relevant of the REESS subsystem.

       3. Procedures

       3.1. General test conditions

       The following requirements and conditions shall apply to the test:

           (a) The test shall be conducted at a temperature of at least 0 °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 are relevant for the outcome of the test shall be operational.

       3.2. Test procedure

       A vehicle based test or a component based test shall be performed at the discretion of the manufacturer:

       3.2.1. Vehicle based test

       The Tested-Device shall be mounted in a testing fixture simulating actual mounting conditions as far as possible; no combustible material should be used for this with the exception of material that is part of the REESS. The method whereby the Tested-Device is fixed in the fixture shall correspond to the relevant specifications for its installation in a vehicle. In the case of a REESS designed for a specific vehicle use, vehicle parts which affect the course of the fire in any way shall be taken into consideration.

       3.2.2. Component based test

       In case of component based test, the manufacturer may choose either gasoline pool fire test or LPG burner test.

       The Tested-Device shall be placed on a grating table positioned above the pan, in an orientation according to the manufacturer's design intent.

       The grating table shall be constructed by steel rods, diameter 6-10 mm, with 4-6 cm in between. If needed the steel rods could be supported by flat steel parts.

       3.3. Gasoline pool fire test set up for both vehicle-based and component-based test.

       The flame to which the Tested-Device is exposed shall be obtained by burning commercial fuel for positive-ignition engines (hereafter called "fuel") in a pan. The quantity of fuel shall be sufficient to permit the flame, under free-burning conditions, to burn for the whole test procedure.

       The fire shall cover the whole area of the pan during whole fire exposure. The pan dimensions shall be chosen so as to ensure that the sides
