| DIN5510/DIN5510-2-2009 – German railway vehicles materials fire test standards
1. The standard - the German railway vehicle fire test standard DIN5510 -2-2009-05 / DIN 5510-2
DIN5510-2-2009-05: railway vehicle to prevent burning - part 2: the combustion characteristic of materials and components and the concurrent combustion phenomenon - classification, requirements and test methods
Effective date: This standard shall come into force since May 1, 2009
Introduction:
Since May 1, 2012, on May 1, 2009, after the research and development of vehicles must be in compliance with these standards.
Transition: Since May 1, 2014 at the latest, still can supply only conform to the standard of the vehicle.
2. The standard applicable scope - now DIN 5510-09-05 railway vehicles materials flammability test
This standard is suitable for railway vehicles, the vehicle belongs to the railway construction and operation rules (EBO), narrow gauge railway construction and operation rules (ESBO), magnetic levitation railway construction and operation rules (MbBO) as well as the construction and operation of the trams (BOSstrab) range. This standard has set the following objectives:
- combustion characteristic and the classification of the concurrent combustion phenomenon,
- and the necessary test method
- in order to prevent fire, the combustion characteristic of materials and components used in fabrication of vehicle and concurrent combustion phenomenon of the necessary requirements.
3. The standard brief -DIN5510-2-2009-05 railway vehicles materials flammability test
To the combustion characteristics of materials and components and the concurrent combustion phenomenon (smog formation, drop characteristics) are classified, thus produce the flammability, smoke and drop level and to allow certain toxicity index in the form of exposure time.
These grades are used to determine the flammability of materials and components used in fabrication of vehicle and the requirements of concurrent combustion phenomenon.
4. DIN5510-2 German locomotive fire test is mainly focus on the following aspects:
4.1 level test
(1) S1 level test combustion (handle, handrail, etc.) the widget
Test method: DIN, DIN 53438-2, 53438-1 DIN 53438-3
Rating: start from the burner flame hit point measurement, the widget on the formation of the flame peak is not more than 15 cm.
(2) S2 - S5 burning level test - general locomotive test
Test method: DIN 54837 - railway vehicle with materials and components - combustion characteristic test
Rating: S2 - S5, ST1 - ST2, SR1 - SR2)
Fire retardant grade S2 S3, S4, S5
Drop level ST1 ST2 smoke level SR1 SR2
Drip situation is no drop drop light attenuation is 100% or less min 100% or less. Min
(3) floor coverings level test - burning rubber floor, the floor materials such as aluminum honeycomb board
Test method: or DIN DIN EN ISO 9239-1 4102-14
Rating: SF1 - SF3
Burning level SF1 SF2 SF3
Critical heat radiation is 2.5 KW/m2 or 4.5 KW/m2 or 2.5 KW/m2 or more
Light attenuation integral no requirement of 2500 or less (min) % * 750 or less (% * min)
(4) wire and cable burning level test
Test method: DIN EN 60332-1-2 single cable vertical flame test
DIN EN 50266-2-4 / DIN EN 50266-2-4 root into a bunch of vertical flame test
DIN EN 61034-1 / DIN EN 61034-2 smoke density test
(5) the seat combustion level test
Test method: DIN EN 1201-1 and DIN EN 1201-2
(6) electronic components fire rating test
Test method: DIN EN ISO 4589-2 or DIN EN 60695-11-10
Rating: oxygen index (OI 28% or 30% or more
4.2 toxicity test
Test method: DIN EN ISO 5659-2
DIN EN 50305 Se 9.2
Rating: the FED (tzul) < 1 or CIT 10 or less
4.3 the development of the smoke level test:
Combustion experiment was carried out, if the combustion grade of S2 - S5, also need a smoke development level test.
Test method: DIN 54837
Rating: SR1 has not been achieved, the SR1 and SR2
Do not meet the SR1: > 100 (% * min); SR1:100 or less (% * min); SR2:50 or less (% * min)
4.4 level drop test:
During tests according to DIN 54837, it is necessary to confirm the material will produce phenomenon of molten drops down.
Test method: DIN 54837
Rating: ST1 - ST2
ST1: molten drop, ST2: did not drop or melt drip drip.
4.5 the main test items and standards
Combustible classification: S1 - S5, SF1 - SF3
Smoke classification: the development of SR
