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.

UL Solutions achieves General Motors approval as a provider of key testing protocols
As a global leader in safety science, UL Solutions proudly announces our Northbrook laboratory’s official recognition by General Motors (GM) as an approved provider of the following battery management system (BMS) tests:
- GMW 18435 — Test Procedure of Abusive Flame Test Procedure of Thermal Barrier Materials
- UL 2596 — Test Method for Thermal and Mechanical Performance of Battery Enclosure Materials, Torch and Grit (TaG) test
Both tests assist GM in selecting the best materials for construction and use in and around lithium-ion battery enclosures, helping to mitigate the effects of thermal runaway scenarios.
