Determination of fire properties of aircraft equipment (materials for cabins and cargo holds/cables).

The defined flame exposure developed in the test method simulates the resistance of the specimens to flame exposure. In the horizontal test method (DO 160H/FAR 25853), a horizon- tally arranged specimen is exposed to a defined flame in a test chamber, the surface of the specimen facing the gas burner.

In the 60° test, a cable is clamped at a 60° angle by means of a spring. In horizontal tests, the combustion rate is determined. In the 60° test, the length of the burned area of the cable insu- lation is determined and whether and how long it burns.

It is tested whether burning material detaches from the sam- ple, falls down and how long the burning time of the fallen parts is. The burning rate is also determined.
