BS7211電纜阻燃防火測試

BS 7211:1998 Electric cables-Thermosetting insulated, non-armoured cables for voltages up to and including 450/750V, for electric power, lighting and internal wiring and having low emission of smoke and corrosive gases when af??fected by fire.
BS 7211:1998 著火條件下，熱固性絕緣電纜，電壓在450V-750V及以下的非鎧裝電纜的低煙及低腐蝕性的要求。

BS7211主要測試項目：

多根成束燃燒測試Flame propagation on multiple cables

根據BS EN 50266-2-4進行電纜多根成束垂直火焰燃燒測試。
the cable shall be tested in accordance with BS EN 50266-2-4,The test shall be carried out on a sample of comleted cable.

煙釋放量測試 Smoke emission

根據BS EN 50268-2進行測試，煙密度測試（光透射率）應不小於60%。
According to BS EN 50268-2 to carry out smoke density testing, the minimum light transmittance shall be 60%.
