Product Specification

UL 2596 Torch and Grit Test Apparatus for Battery Enclosure Flame Ejection Testing

Product information:

The UL 2596 Test Method 1 Torch and Grit (TaG) Test Apparatus is a professional testing device specifically designed for the safety assessment of lithium-ion battery casing materials for electric vehicles. This device strictly adheres to the requirements of the US UL 2596 standard, simulating the 3kW high-temperature flame jet and high-speed particle erosion generated during battery thermal runaway. Through 20 cyclic impact tests, it accurately evaluates the casing material's resistance to flame penetration, thermal shock, and mechanical durability, ensuring that the battery pack will not experience flame leakage or structural failure under extreme conditions. This equipment is widely used for certification testing of battery pack casings, housing covers, and composite materials for new energy vehicles. It is an essential instrument for battery material R&D and manufacturing companies, as well as third-party testing laboratories, helping manufacturers meet the stringent safety compliance requirements of the North American market.
