Flexiburn EN 13772

Burning behaviour of curtains according to EN 13772 - vertical flame spread

The Flexiburn apparatus allows to measure the vertical flame spread of curtains caused by the heat released by a fire. The fabric is exposed to a large ignition source of radiant heat.

This new test method is the third one in a series of test methods, next to ignitability (EN 1101) and flame spread (EN 1102). On the basis of these three tests, curtains can be classified according to the specifications of EN 13773 in five classes of fire safety.
