NTIS: PB/81-101990 :95 pages
Noise control programs have been initiated on several types of mining equipment and vehicles that can be used in underground coal mines. The materials that are used in these programs have not been tested for flammability properties. The objective of this program was to select approximately 100 acoustic materials for flammability evaluation. A variety of materials were selected for measurement according to ASTM e-162 procedures. A radiant heat energy source was used to measure flammability properties of 15.2- By 45.7-Cm samples. In the absorptive materials category, 45 percent of the materials tested had a flame spread index of less than 25. For barrier, damping, and isolation materials the corresponding values were 40, 43, and 9 percent.
