UL 1581 Electrical Cables and Wires Flame Test Chamber

UL 1581 Electrical Cables and Wires Flame  Test Chamber

Manufacturer: Wazau – Germany

SCOPE The testing device is used to determine the flame propagation through electrical cables and wires.

 PRINCIPLE

Vertically oriented test specimen

The cable under test is exposed to a 500 W flame (125 mm high) three times for 60 seconds with an interval of 30 seconds. This determines whether the flame is propagated longitudinally.

 Horizontally oriented test specimen

The cable under test is exposed to a 225 W flame (50 mm high) for 30 seconds. This determines whether the flame is propagated longitudinally.

The tests provide information on whether the specimens leak or release emissions into the environment during flame impingement.

FEATURES
