Anotace

describes four methods for measuring the propagation of a flame along a conveyor belt which has been exposed to a relatively high localized heat source such as a fire. The damage suffered by the conveyor belt, as well as its tendency to support combustion, is measured by observing the extent to which the fire spreads along the test piece.
Method A uses a test piece 2 m in length and consumes propane gas through the burner at the rate of (1,30 _ 0,05) kg per 10 min.
Method B uses a test piece 2,5 m in length and consumes propane gas through two burners mounted above and below the test piece trestle at the rate of (1,30 _ 0,05) kg per 10 min for each burner.
Method C uses a test piece 1,5 m in length and consumes propane gas through the burner at the rate of (565 _ 10) g per 50 min.
Method D uses a test piece 1,2 m in length and consumes propane gas through the burner at the rate of
150 l/hr (D1) or 190 l/hr (D2)
