Fire Testing to Railway Components - EU Standard: EN 45545-2:2013+A1:2015
Standard - EN 45545-2:2013+A1:2015 Fire Testing to Railway Components
EN 45545-2:2013+A1:2015 Railway applications - Fire protection of railway vehicles-Part 2: Requirement for fire behaviour of materials and components.
EN 45545-2:2013+A1:2015 Fire Testing to Railway Components
Railway rolling stock material for fire testing standards, national testing standards and methods are different, the EU launched a program called Firestarr Project to study and establish a set of railway vehicles, materials, flammability, flame spread rate, heat release the amount of smoke emission and toxicity testing.
According to vehicle material end-use and fire risks, will be divided into R1-R26. The 26 different categories.
Fire hazard levels (HL1 to HL3) result from different dwell times and are related to operation and design categories
EN 45545-2:2013+A1:2015 Design categories
All vehicles are classified due to their design as follows:
-A: automatic vehicles having no emergency trained staff on board;
-D: double decked vehicles;
-S: sleeping and couchette cars;
-N: all other vehicle
These design categories generate fire scenarios which lead to different dwell times.
