Abstract: The European standard EN 45545-2 stipulates the fire safety performance requirements of materials and components used in railway vehicles.This paper analyzes the relevant requirements of wires and cables in the European standard EN 45545-2 from three aspects: safety hazard levels, fire safety requirements and reference test method details. Combined with normative reference documents and the EU LVD low voltage directive 2014/35/EU harmonized standards and other documents, suggestions are made for the selection of the reference test standard version, and the main test details are described, which will help practitioners in the wire and cable industry understand and implement the standard.
Key words: European standard EN 45545-2; wire and cable; requirements for fire
