BAIJIAN - Third party testing organization
Due to the complex structure and numerous passengers of the subway、 subway rail transit vehicles must have special requirements for fire prevention in their design、 manufacturing、 and transportation. The materials used in domestic subways are generally tested and certified in accordance with relevant European standards such as BS 6853 in the UK、 NF F 16-101 in France、 and DIN5510-2 in Germany. The most stringent of these is the British BS 6853 fire protection standard
