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.

Battery Enclosure Materials-Test Method 1: Torch and Grit (TaG)
Test
Test Product Application:
This testing setup is primarily used to evaluate the thermal and
mechanical properties of lithium-ion battery casing materials for
electric vehicles (EVs), simulating the impact of high
temperatures, flame jets, and particle erosion on the materials
during thermal runaway.
