Size Distributions of Particles Extracted from Different Materials Compared with the MIL-STD-1246 Particle Size Distribution

Autor: Roger Welker

Publikováno v: Journal of the IEST. 43:25-29

MIL-STD-1246 particle-size distribution is the basis for specifying the particle cleanliness of surfaces for many governmental and industrial applications. MIL-STD-1246 states that naturally occurring particle contamination on surfaces follows a log-

Autor: E. Joseph Duckett, Roger Welker, John Wagner, Brian Rogers, Vera Usdind

Publikováno v: American Industrial Hygiene Association journal. 41(12)

Airborne dusts at a resource recovery pilot plant were sampled and analyzed to determine physical, chemical and microbiological characteristics. The sampling device was a multi-stage impactor equipped with a pre-collector. Dusts are primarily fibrous
