LIST OF ANNEXES U.K.

ANNEX IV TEST TO DETERMINE THE HORIZONTAL BURNING RATE OF MATERIALS

4. Procedure U.K.

4.1. Place samples with napped or tufted surfaces on a flat surface and comb twice against the nap using the comb ( 2.5). U.K.

4.2. Place the sample in the sample holder (2.2) so that the exposed side will be downwards to the flame. U.K.

4.3. Adjust the gas flame to a height of 38 mm using the mark in the chamber, the air intake of the burner being closed. Before starting the first test, the flame shall burn at least for 1 min for stabilization. U.K.

4.4. Push the sample-holder into the combustion chamber so that the end of the sample is exposed to the flame, and after 15 seconds cut off the gas flow. U.K.

4.5. The measurement of the burning time starts at the moment when the foot of the flame passes the first measuring point. Observe the flame propagation on the side burning faster than the other (upper or lower side). U.K.

4.6. Measurement of burning time is completed when the flame has come to the last measuring point or when the flame extinguishes before coming to the last measuring point. If the flame does not reach the last measuring point, measure the burnt distance up to the point where the flame extinguished. Burnt distance is the decomposed part of the sample, which is destroyed on its surface or in the interior by burning. U.K.

4.7. In so far as the sample does not ignite or does not continue burning after the burner has been extinguished, or when the flame extinguishes before reaching the first measuring point, so that no burning time is measured note in the test report that the burning rate is 0 mm/min. U.K.

4.8. When running a series of tests or repeat tests, ensure that the combustion chamber and sample holder have a maximum temperature of 30^oC before starting the next test. U.K.
