適用范圍：This European Standard specifies a test method for cables designed to have intrinsic resistance to fire and intended for use as emergency circuits. The standard is applicable to power and control cables for emergency circuits of rated voltage not exceeding 0,6/1 kV. The test method is intended for cables with an overall diameter exceeding 20 mm. Cables of smaller diameter shall be tested in accordance with EN 50200. The test method is based on the direct impingement on the cable of the flame from a propane burner giving a constant temperature attack of a notional 842 ℃ and under the influence of mechanical impact.
