The hand lay-up FRP composite material SMC Germany DIN5510-2 burning and toxicity test
Hand Lay-up composite DIN5510-2 / FRP composites DIN5510-2 / SMC - DIN5510-2 / DIN5510-2 fire retardant test
FRP (Fiber Reinforced Plastic) is also called GRP (Glass Reinforced Plastic), the Fiber Reinforced Plastic, generally refers to with Glass Fiber Reinforced unsaturated polyester, epoxy resin with phenolic resin was selected. With glass fiber or its products as reinforced material reinforced plastic, appellation for glass fiber reinforced plastic, or appellation FRP. Due to the use of technology is different, can be divided into mold and hand lay-up, etc. Because use different varieties of resins, therefore a polyester FRP, epoxy glass fiber reinforced plastic, phenolic FRP serial. As these material has Light and hard, non-conductive, high mechanical strength, recycling, less corrosion characteristics, so it can replace steel manufacturing machine parts and automobile, ship's shell, etc.
Due to the product in the locomotive and train a large number of use, so the CSR and CNR, according to the requirements of the end-user of the order need the material meets the requirement of flame retardant and toxicity of German ministry of railways, the specific requirements for the fireworks toxicity test data.
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.
DIN5510-2: railway vehicle fire prevention; Part 2: the train material and components combustion performance and concurrency phenomenon, classification, requirement and test method
Molded FRP GPR composites used in exterior wall, interior wall, ceiling, such as the locomotive, ground DIN5510-2 focus on the following aspects:
1. The flammability classification: S2 - S5 level (S2, S3, S4, S5) according to DIN 54837 (gas flame test) to test
S2: after 30 cm or less damage range, burning time there is no requirement.
S3:25 cm or less damage range, burning time after 100 s or less
S4:20 cm or less damage range, burning time after 10 s or less
S5: after damage range = 0 cm, burning time = 0 s
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
4. The toxicity test: EN ISO 5659-2, request the FED (tzul) 1 or less
DIN5510-2 standards
Ground material combustion reaction DIN EN ISO 9239-1: test SF1 - SF3 level requirements.
Reaction to fire tests for floorings - Part 1: Determination of the behaviour using a radiant heat source (EN ISO 9239-1:10)
DIN 54837: the gas flame test to determine the S2 - S5 burning level
Testing of materials, small components and component sections for rail vehicles - Determination of behaviour using a gas burner
DIN 53438: Testing of combustible materials, and the response to ignition by a small flame, S1 level combustion test.
DIN EN ISO 5659-2: Toxicity testing smoke Toxicity test
Other test standard:
Railway vehicle fire DIN5510-1; Part 1: flame retardant grade, flame retardant technology measures and instructions;
DIN 5510-2: railway vehicle fire prevention; Part 2: the train material and components combustion performance and concurrency phenomenon, classification, requirement and test method;
DIN5510-4 railway vehicle fire; Part 4: vehicle structure design; Safety technical requirements;
DIN5510-5 railway vehicle fire; Part 5: electrical equipment; Safety technical requirements;
DIN5510-6 railway vehicle fire prevention; Part 6: additional measures, the performance of the emergency braking device, signal system, alarm system. The performance of the combustion control system, Safety technical requirements.
