BS 7846: Electric cables – 600/ 1000V armoured fire-resistant cables
BS 7846: Electric cables – 600/ 1000V armoured fire-resistant cables - Test Standard：
BS 7846:Electric cables – 600/ 1000V armoured fire-resistant cables having thermosetting insulation and low emission of smoke and corrosive gases when affected by fire
BS 7846: Electric cables – 600/ 1000V armoured fire-resistant cables -Scope:
This British Standard specifies the requirements for construction and performance,and describes methods of test, for armoured fire-resistant cables with thermosetting insulation and of rated voltage 600/1000V and low emission of smoke and corrosive gases when affected by fire.
The circuit integrity performance under fire conditions is assessed on the basis of various tests which either separately measure resistance to fire,resistance to fire with water,and resistance to fire with water,and resistance to fire with mechanical shock(Categories F1 and F2),or in combination measure resistance to fire with mechanical shock and water.(Category F3)
