Flame Spread Evaluation of Ventilation Cloth.
NTIS: PB 209 539 :9 pages
Comparative data from ASTM method of test e-162 and large-scale trials in the experimental mine show that the flame-spread quality of brattice cloth and other ventilation control materials can effectively be evaluated by either method. Materials having a flame spread index of 25 or less, as determined by the simpler and more economical laboratory test ASTM e-162, do not present a serious fire hazard when used in coal mines.
