Silica dust test for respiratory protective devices.
NIOSH 1977 Jul; :1-38
The results of a silica (7631869) dust test designed to determine whether a respirator meets the test performance requirements in Title 30 Part 11 of the Code of Federal Regulations, Subparts 11.140- 4 and 11.162-7 for maximum allowable penetration and in Subparts 11.130-9, 11.140-12, 11.162-1, and 11.183-4 for maximum allowable breathing resistances are reported. The test evaluated the performance of air purifying respirators against dusts of materials with a time weighted average (TWA) not less than .05mg/m3 or 2mppcf. The test also evaluated the resistance performance of a respiratory protective device used for protection against dust material with a TWA less than 0.05mg/m3 or 2mppcf and resistance performance of a respiratory protective device used for protection against pesticides.
