Qingdao subway fire safety standards to achieve the highest BS6853

Fire safety standards for new vehicles off the assembly line in Qingdao subway to reach the world's highest level , the most stringent standard BS6853 . Subway cars all non-metallic materials with flame retardant , low toxicity , low smoke material to ensure that avoid, reduce fires , ensure safe operation of the vehicle . BS6853 technology sharing site to share with you the British BS6853 Details standard , Tel 025 -86583475 .

Qingdao Metro materials needed to achieve BS6853 standard , BS6853 standard focuses on what areas :
BS6853 standard is mainly concerned with fire retardant materials testing, low smoke properties, low toxicity , specific test methods and criteria are as follows :

Metro Materials Testing Standards BS6853 fire retardant properties and projects :
BS476-6 flame spread index test
BS476-7 Product flame surface extends Level Test Methodology
BS4589-2 oxygen index test
BS4589-3 temperature index test
BS EN 4066/BS 4066-3 wire and cable bundles vertical flame

Metro Materials Testing Standards BS6853 low smoke properties and projects
BS 6853 Annex D8.3 smoke density test a small area of ??the material
BS 6853 Annex D8.4 smoke density test panel material
BS 6853 Annex D8.5 smoke density test seat
BS 6853 Annex D8.6 floor smoke density test
BS 6853 Annex D8.7 cable smoke density test

Metro Materials BS6853 toxicity testing standards and project performance
BS 6853 Annex B.1 toxicity test method based on the quality of
BS 6853 Annex B.1 area -based toxicity testing methods

According locomotive operating environment , the performance requirements for locomotives used material is divided into three levels, as BS6853 Ⅰa and Ⅰb class ( underground ), BS6853 Ⅱ class ( surface ) . BS6853 Ⅰa most advanced , most demanding high .
BS6853 Ⅰa: the majority of time is running without a sidewalk leading to the outlet side of the monorail track and escape tunnels, or run underground for quite some time sleeper car , or train unattended operation.
BS6853 Ⅰb: the majority of run time where there is access to the sidewalk side exits and escape channel multitrack tunnels or underground for quite some time without running the sleeper car .
BS6853 Ⅱ: the majority of the surface of the tunnel does not run during the operation of the vehicle .
