英国BS6853标准根据产品最终用途不同(地板，墙壁，天花板吊顶，小区域材料，电缆等)，其测试标准及测试方法有所不同。床垫BS6853测试主要关注如下内容。

1. 床垫BS6853标准及定义
BS6853:1999: Code of practice for fire precautions in the design and construction of passenger carrying trains.
BS6853:1999: 载客列车设计与构造防火通用规范.

BS6853 Annex D: Methods for measuring smoke density
BS6853 Annex D: 烟密度的测试方法

烟密度一般火灾时能见度相关，因为能见度下降会使人们更难以逃离火灾现场。从而增加了烟雾毒性、火焰、热量给人们带来的生命安全风险。

对于英国载客列车所用材料有五种不同的测试方法去评判烟雾密度。

BS6853 Annex D五种不同的测试方法如下:
