This par1 of EN 12881 describes three methods for measuring the propagation of a flame along a conveyor
belt which has been exposed to a relatively high Iocalised heat source such as a fire. The damage suffered by
the conveyor belt, as well as its tendency to support combustion, are 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.
