Rubber and plastic insulation products German DIN5510-2 standard fire retardant test

Rubber and plastic insulation material products as has good heat preservation performance and flame retardant properties of energy-saving products, currently used more generally materials made by PVC (polyvinyl chloride) and NBR (nitrile butadiene rubber).Of course, should be in locomotives and train these materials need to comply with the German DIN5510-2 standard of the flame retardant performance testing of CSR and CNR subordinates locomotive company material suppliers to pay more attention to its conformance testing standard.
 
Germany DIN5510-2 standard
DIN 5510-2: Preventive fire protection in railway vehicles; Part 2: Fire behaviour and Fire side effects of materials and parts, classification, requirement and test methods.
 
Rubber and plastic insulation material products DIN5510-2 test items and standards in Germany
DIN5510-2 flame retardant phenomenon mainly focus on the following aspects:
 
DIN 54837: Testing of materials, small components and component sections for rail vehicles - Determination of'm behaviour using a gas buner.

1. Combustible classification: S2 - S5 level (S2, S3, S4, S5)
2. Drop performance: ST1 - ST2 according to DIN 54837 confirm that material test appeared phenomenon of molten drops down
3. The development of smoke classification: SR1 - SR2 according to DIN 54837 smoke release quantity measurement
 
At the same time, in the new DIN5510-2 standard of 2009 version and focus on the aspects of toxicity performance, the test methods:
EN ISO 5659-2: single room optical density of smoke test method
Toxicity test: EN ISO 5659-2, which requires the FED (tzul) 1 or less
 
Rubber insulation products at the request of the locomotive of flame retardant and toxicity, DIN5510-2 in table 5 in Germany have relatively clear requirement, general requirements to S4, ST2 and SR2 flame retardant requirement, at the same time its toxicity vehicle exposure time of 15 minutes and 30 minutes all conform to its limit.
