The test specimen is put on a specimen holder that is hung in a test cabinet. A burner flame is applied to it for 15s. The time to reach a marked point is measured. Also the burning droplets are observed by means of a paper placed under the specimen.
‘Fire shaft’ test
A test specimen is hung vertically in a test cabinet with a burner in it. It is subjected simultaneously to a flame for 10min and a constant flow of air from below. The temperature of the smoke and the undamaged length of the specimen are measured.
