1 Scope

1.1 These requirements cover tests for thermal and mechanical performance of battery enclosure materials in response to stresses representative of thermal runaway of lithium-ion cells used in electric vehicles.

1.2 The performance characteristics of a material determined by this test method shall not be assumed to correlate with its performance in the end-use application. The actual response of materials to thermal and mechanical stresses depends upon the size and form of the material, as well as the end-use application of the product using the material.

1.3 Tests conducted on a material under the conditions specified are intended to provide information when comparing the relative performance characteristics of different materials, or assessing any change in performance characteristics prior to or during use.
