How to perform en45545 fire test for battery shell

in the light of EN45545 EU standard for flame retardant and fire protection of rail transit train materials , Non metallic shell of battery （ Common are PPO plastic 、ABS Plastic etc. ） Consider implementing R1 or R22 Fire test items , It mainly depends on the weight and area of the battery shell .

If the surface area of the plastic housing of the battery exceeds 0.2 Square meters , It generally needs to be carried out according to the surface material EN45545-2 R1 Fire detection of the project , The main test items include ISO5658-2 Flame spread test ,ISO5660 Cone calorimeter method for determination of heat release test ,ISO5659-2 Optical density test ,EN17084 Smoke toxicity test （EN45545-2:2020 The latest standard ）.

If the surface area of the plastic housing of the battery does not exceed 0.2 Square meters , And the weight of the used gram exceeds 500 g , It needs to be executed according to the electrical components of small area materials EN45545-2 R22/R23 Fire detection of the project , The main test items include EN ISO4589-2 OI Limiting oxygen index test ,EN ISO 5659-2 Optical density test ,EN17084 Smoke toxicity test .
