EN 45545-2: Fire protection of railway vehicles – Part 2: Requirement for fire behaviors of materials and components （R22/R23)
EN 45545-2 Fire test to railway component – Standard Brief
The EN 45545-2:2013 supersedes CEN/TS 45545-2:2009, which is withdrawn, and together with EN 45545-1:2013, EN 45545-3:2013, EN 45545-4:2013, EN 45545-5:2013, EN 45545-6:2013 and EN 45545-7:2013. The EN 45545 will also supersedes BS 6853, NF F16-101and DIN 5510 -2 standard.
This part of EN 45545 specifies the reaction to fire performance requirements for materials and products used on railway vehicles as defined in EN 45545-1.
The operation and design categories defined in EN 45545-1 are used to establish hazard levels that are used as the basis of a classification system.
For each hazard level, this part specifies the test methods, test conditions and reaction to fire performance requirements.
It is not within the scope of this European Standard to describe measures that ensure the preservation of the vehicles in the event of o fire.
