European EN45545 / EN45545-2-2013 standard for fire and toxicity test

European EN45545 / EN45545-2-2013 standard for fire and toxicity test

1. The standard - Rail transit vehicle material fire test standard EN45545 /EN45545-2 railway applications - railway vehicle fire protection - part 2: materials and components of the fire protection requirements.
The European railway on March 8, 2013 formally announced EN45545-2 updated version of the standard. there are some difference between EN45545-2-2009 and EN45545-2-2013 standard .

2. EN45545 / EN45545-2 standard brief
EN45545-2 the latest standard of 2013 edition, the main focus on the combustion performance of materials, thermal properties, such as emission, smoke density and toxicity. EN45545-2 standard according to the material end use, divided into R1 - R26, a total of 26 different categories. Depending on the type of vehicle and the operating environment, EN45545-2-2013 standard could be divided into HL1 fire danger rating, HL2, HL3, a total of three fire risk level.
Eu EN45545-2 standard will plan to replace BS6853, NFF16-101,, DIN5510 NFF16-102-2, UNI CEI 11170-3, prE10.02.977.3, UIC564-2 eu railway vehicles materials such as fire test standards.

3. EN45545 / EN45545-2 standard includes the following rail vehicles
EN45545-2 standard specifies the following vehicle (subway train high-speed maglev train locomotive train, light rail trams trolleybus coach) fire burning test performance, smoke, toxicity, properties, such as combustion heat value.
