Test Procedures for Fire Alarm Cables


Test on gases evolved during combustion
This test procedure provides information if the insulation material of the cable sheath creates corrosive gases in the event of fire. Halogen parts or other material in small quantities can be easily identified with this test due to the strong change of pH and conductivity. The conductivity is < 10mS/mm

Test for vertical flame propagation
(single insulated wire or cable)
This test method tests a cable sample (length: 60 cm) for burning behaviour. The flame must extinguish itself, and the burn damage must not reach the upper end of the cable sample.

VDE 0482-332-1-2

Test for vertical flame spread

(bunched wires or cables)

This test method tests a cable bundle (length: 360 cm) with regard to fire propagation. The flames must extinguish themselves, and burn damage must not exceed a defined height.

Measurement of smoke density

This test checks smoke development when burning the cable or the impairment of the visibility by burning cables. The reduction in light transparency is measured in a standard chamber
