The German standard DIN 5510 is the international standard for fire and smoke safety testing of rail vehicle materials

The German standard DIN5510 is one of the most commonly used standards for fire and smoke safety testing of domestic and international rail vehicle materials. What do many customers mean and require for the German standard DIN5510 combustion level S5? The burning level S5 is the highest level of the German standard DIN5510 test. The DIN5510 standard not only requires the material to have fire resistance and flame retardant properties, but also needs to have low smoke and low toxicity properties at the same time. Zonsky Testing Instrument Co., Ltd., you share the specific content of the German standard DIN5510-2 S5/ST2/SR2 test and the related equipment that meets the standard test.

DIN5510-2 test items, standards and requirements for general materials of rail vehicles

1. Classification of flame retardant fire rating: S2-S5 (S2/S3/S4/S5), tested according to DIN54837 standard.

Requirement of DIN5510 combustion grade S2: the length of product combustion failure does not exceed 30cm.

DIN5510 Combustion Grade S3 Requirements: The length of the product's combustion failure does not exceed 25cm and the post-combustion time does not exceed 100s.

DIN5510 combustion grade S4 requirements: the length of the product's combustion failure does not exceed 20cm and the post-burning time does not exceed 10s.

DIN5510 burning grade S5 level requirements: product burning damage length: no and after-burning time: no.

2. Classification of smoke emission: not reaching SR1, SR1-SR2

3. Droplet classification: ST1-ST2

4. Smoke toxicity test: DIN EN ISO 5659-2, European DIN5510 standard requires that the toxicity index is not greater than 1.

DIN5510-2 Test Items and Standards for Rail Vehicle Floor/Ground Materials

1. Floor material fire rating test: SF1-SF3 (SF1/SF2/SF3), tested according to DIN EN ISO 9239-1 critical heat radiation.

DIN5510-2 SF1 level requirements: critical thermal radiation ≥2.5KW/M2, and no requirement for light attenuation integral.
