PrCEN/TS 45545-2: Fire Test to Railway components

&   Ecosafene Products Service Co.,Ltd have rich experience to provide prCEN/TS 45545-2 fire test to railway components
Ä  EN45545-2 / PrCEN TS 45545-2 Fire test to railway componet - Standard
ü  EN45545-2: Fire protection of railway vehicles - Part 2: Requirement for fire behaviours of materials and components
Ä  EN 45545-2 / PrCEN TS 45545-2 Fire Test to railway componentsStandard Brief
ü  The Content of part 2 is
Ø  Functional description of the fire safety objectives
Ø  The generic material classes and the requirement classes
Ø  Test methods according to the generic material classes
Ø  Characteristic requirement of the system test
Ø  Requirements in principle for selection of testing and test samples
Ø  Interior material construction
ü This European standard specifies:
Ø  Measures on railway vehicles for fire protection
Ø  Verification of these measures
Ø  The objective of the measures and requirements specified in this European standard is to protect passengers and staff in railway vehicles in the event of a fire on board
Ø It is not within the scope of this standard to describe measures which ensure the preservation of the vehicles in the events of a fire
üRailway vehicles in this standard are
Ø   Locomotives                       Ø Multiple units
Ø   Coaches                            Ø   Light rail vehicles
Ø   Underground vehicles          Ø Trams
Ø Trolley buses (only in relation to the electrical equipment)
Ø Magnetic levitation vehicles 
ü For the objectives the following possible scenarios are taken in account
Fire resulting from accident or arson typical ignition models involving newspaper, matches, cigarettes and gas lighters shall be taken into consideration in any position freely accessible to passengers and staff.
Fire resulting from technical defects ignition models, comparable to electric arcs or abnormal temperatures shall be take into consideration. The effects of any flammable gases or flammable liquids which may be present shall also be taken into account.
Fire resulting from larger ignition models to reduce the hazards to passenger and staff, the following requirements, which are defined in all parts of their technical specification, are intended to cover cases with bigger ignition models e.g. Passenger clothes or passenger luggage 
Ä EN 45545-2 / PrCEN TS 45545-2 Fire Test to railway components - Scope
ü  The some parameters for evaluation of reaction to fire are spread of flame
Ø  Ignitability            Ø  Heat release
Ø  Smoke                Ø  Toxicity
ü  The test methods are unique, taking in account the different materials classes like
Ø  Structural surface related products
Ø  Furniture products
Ø  Electrical equipment
Ø  Mechanical equipment
Ä  EN 45545-2 / PrCEN TS 45545-2 Fire Test to railway components – Test Method
ü  Implementing compliant fire safety measures
Ø  The small scale test methods for testing the fire safety properties are checked to be in consistence with the real scale tests in vehicles
Ø  The flame spread test is also used in the IMO regulation
Ø  Smoke and toxic measurement uses the European smoke chamber EN ISO 5659
