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, a separate Tested-Device may be used.

       The test pulse shall be within the minimum and maximum value as specified in Tables 1 to 3. A higher shock level and /or longer duration as described in the maximum value in Tables 1 to 3 can be applied to the Tested-Device if recommended by the manufacturer.

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

Annex 9D

Mechanical integrity

       1. Purpose

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

       2. Installations

       2.1. This test shall be conducted with either the complete REESS or with a related REESS subsystem(s) including the cells and their electrical connections. If the manufacturer chooses to test with related 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 as recommended by the manufacturer.

       3. Procedures

       3.1. General test conditions

       The following condition and requirements shall apply to the test:

           (a) The test shall be conducted at an ambient temperature of 20
