EN45545-2 / PrCEN TS 45545-2 Testing of flame retardant and fireproof materials for rail vehicle materials - Scope of application of the standard :
The purpose of the EN45545-2 European rail vehicle flame retardant and fire test standard is to formulate rules related to material selection based on the material's flammability and related response to fire, smoke impermeability and toxicity of gas emissions.
There are the following indicators and parameters to evaluate fire protection performance:
Combustion Heat release
Smoke Toxicity
Testing methods are unique and depend on the material’s classification:
