The fir
23、e being simulated is one not caused by a local heat source but by materials around the conveyor belt which catch fire following exposure to other heat sources. Attention is drawn to the fact that in assessing the overall flammability characteristics of conveyor belting for specific installations, it
24、 is not sufficient to rely solely on any single method of test but consideration should also to be given to the individual site location.
