BS6853 Annex B: Determination of weighted summation of toxic fume, R
BS6853 Annex B: 有毒烟雾的加权总和R

针对英国载客列车设计与构造防火通用规范，有两种不同的毒性测试方法被用来测试材料所产生的烟雾毒性。这两种测试方法如下：

BS 6853 Annex B.1: 基于质量的试验方法(NF X 70-100)，该方法用于小区域材料(表7和表8)，织物（表11）和电缆（表13和表14）。

BS6853:1999: Code of practice for fire precautions in the design and construction of passenger carrying trains.
BS6853 Annex B: Determination of weighted summation of toxic fume, R

BS 6853 Annex B.2: Area based test method（prEN2824，prEN2825，prEN2825). An area based method should be used used for sufaces(Table 1,Table 2,Table 3,Table 4,Table 5,Table 6) seat tirm and seat shell(Table 9,Table 10) and mattresses(Table 12).

BS6853:1999: Code of practice for fire precautions in the design and construction of passenger carrying trains.
BS6853 Annex B: Determination of weighted summation of toxic fume, R

The two different methods are as follows:

BS 6853 Annex B.1: Mass based test method(NF X 70-100)，This method should be appkied to minor use materials(table 7 and table 8),textiles(table 11) and cables (table 13 and table14).

BS6853:1999: Code of practice for fire precautions in the design and construction of passenger carrying trains.
BS6853 Annex B: Determination of weighted summation of toxic fume, R

There are two different test methods which can be utilized to determine the toxic fumes produced from materials to be placed on passenger carrying trains in the UK.

BS 476-7: Fire tests on building materials and structures-Part 7 method of test to determine the classification of the surface spread of flame of products.
BS 476-7: 对建筑材料和结构的着火试验-第7部分：产品火焰表面延伸等级确定的测试方法。

BS 476-7:1997 测试方法
测试方法是在燃烧箱内点燃烧样品，点燃源为燃气辐射板及中型燃气喷灯。辐射板的辐射强度在离75mm处为32.5kw/m2(表面),喷灯的火焰高75-100mm, 与辐射板在同一方向施加于试样。

通过BS476-6火焰传播指数的测试，可以用于评估建材产品/建材、动车、火车、地铁材料的防火性能。英国轨道交通车辆防火标准BS6853引用BS476-6测试进行测试。

BS476-6: Fire tests on building materials and structures- Part 6: Method of test for fire propagation for products.
BS476-6:对建筑材料和结构的着火试验—第6部分：产品火焰传播的测试方法。

BS EN 4589-2: Plastics-Determination of burning behaviour by oxygen index –Part 2: Ambient-temperature test
BS EN 4589-2: 塑料-用氧指数法测定燃烧行为-第2部分:室温测试

氧指数: 在规定试验条件下,通入23℃±2℃氧、氮的混合气体，材料恰好维持燃烧所需的最小氧浓度的试验方法。

国标GB/T2406与此BS EN 4589-2标准类似
