Develop, test and integrate batteries according to the standards

See Table 4 for the number of cycles. If the DUT is splashed in the vehicle from only one direction, splash it from this direction only while it is in an as-installed position. Select a severity from Isso 4 and Annex A. The operating mode of the DUT is 1. The minimum functional status shall be class C, as defined in ISO Tests — Test Ka: For undated references, the latest edition of the referenced document including any amendments applies.

The operating mode of the DUT shall be 1. For tests including hotsoak temperature, TmaxHS, see Table 3. Carry out a visual examination with the naked eye, at normal strength of vision, with normal colour perception, at the most favourable distance and with suitable illumination. An additional failure mode not addressed in 5.
