Cable testing for BS6853:1999/BS4066-3/BS 6853 Annex B/BS 6853 Annex D
BS6853:1999-Code of practice for fire precautions in the design and construction of passenger carrying trains.
BS EN 50266-1:2001 Together with BS EN 50266-2-1, BS EN 50266-2-2, BS EN 50266-2-3, BS EN 50266-2-4, BS EN 50266-2-5,it supersedes BS EN 4066-3 which is withdrawn.
As the cable flame spread and burning rate of destruction of the length of the combustion smoke density (light penetration) and the burning of hazardous toxic gas escape on the staff of life play a very important influence. In general, testing cables through these areas to assess。
Cable according to end-use（Interior cables -BS6853 Table 13、Exterior cables-BS6853 Table 14）carry out testing and evaluation：
Cable testing standard for BS6853
BS EN 50266-2-4: Common test methods for cables under fire conditions - Test for vertical flame spread of vertically-mounted bunched wires or cables - Procedures - Category C (cable diameter ≥12mm)
BS EN 50266-2-5: Common test methods for cables under fire conditions - Test for vertical flame spread of vertically-mounted bunched wires or cables - Procedures - Category D (cable diameter ＜12mm)
BS EN 50306: Railway applications-Railway rolling stock cables having special fire performance-thin wall
BS EN 50305: Railway applications-Railway rolling stock cables having special fire performance-test methods
BS EN 50264: Railway applications—Railway rolling stock power and control cables having special fire performance
BS 6853 Annex B: Toxicity
BS 6853 Annex D: Smoke density
BS EN 4066/BS 4066-3: Tests on electric cables under fire conditions. Tests on bunched wires or cables.
BS EN 60332-3-24:2009 Tests on electric and optical fibre cable under fire conditions-Part 3-25: Test for vertical flame spread of vertically mounted bunched wires or cables- Category C
BS EN 60332-3-24/BS EN 60332-3-25: Tests on electric and optical fibre cable under fire conditions-Part 3-25: Test for vertical flame spread of vertically mounted bunched wires or cables- Category D. It is identical to IEC 60332-3-25:2000, incorporating amendment 1:2008. It supersedes BS EN 50266-2-5:2001 which is withdrawn.
