Torch and Grit (TaG) Test

At UL Solutions, we developed a set of test methods, known as Battery Enclosure Material Screening (BEMS), to evaluate the performance of different battery enclosure materials in response to a thermal runaway event, outlined under UL 2596, Test Method for Thermal and Mechanical Performance of Battery Enclosure Materials.

Our Torch and Grit (TaG) test method screens for the dynamic stresses found in a thermal runaway event, focusing on the evaluation of temperature and mechanical abrasion.

We help you:

Test material plaques versus the entire battery assembly, helping to reduce cost and development time.
Screen formulas and constructions during research and development, helping material producers and original equipment manufacturers (OEMs) to evaluate the performance of different battery enclosure materials.
Compare performance between materials.

Our solutions are designed to help material manufacturers, suppliers and automotive OEMs select electric vehicle (EV) battery enclosure materials with greater confidence.
