Railway vehicles are a kind of large passenger traffic, most of the lines are in relatively closed spaces, and are crowded with disorderly people. It is difficult to escape and rescue in the event of a disaster. In recent years, train fire accidents have occurred many times, causing many casualties and serious property damage. Therefore, countries around the world have continuously proposed higher standards for fire safety hazards that may occur in rail transit vehicles.

The latest standards of EN45545-2: 2013 + A1: 2015 are mainly concerned with the properties of materials such as combustion performance, heat release, smoke density, toxicity, etc. The EN45545-2 standard is divided into 26 different categories R1-R26 based on the end use of the material. According to the type of vehicle and the operating environment, the EN45545-2-2015 standard divides the fire danger levels into HL1, HL2, HL3, a total of 3 fire risk levels.

Standard EN 45545-2: 2013 + A1: 2015 focus on the followings

Heat Release

Flammability

Toxicity Test

Smoke Density

Critical Heat Radiation Test

The EN45545 / EN45545-2-2015 standard includes the following railway vehicles

The EN45545-2 standard specifies the following performances (such as subway trains, high-speed trains, maglev trains, locomotive trains, light rail trams, trolley buses, and long-distance buses) for fire test performance, smoke toxicity, and heat of combustion.
