This test evaluates the flame resistance of wire at a 60-degree angle as specified in BSS7324. The specimen is exposed to a controlled flame source for a specified duration, then the flame is removed and the self-extinguishing behavior and extent of damage are assessed.
Flame resistance is a critical safety requirement for electrical wiring and cables, particularly in aerospace and transportation applications. The test verifies that the material will not propagate fire and will self-extinguish within the required time after removal of the ignition source.
