Reported particle size measurement is a function of both the actual particle dimension and shape factor as well as the particular physical or chemical properties being measured. Caution is required when comparing data from instruments operating on different physical or chemical parame...

1.1 This test method covers the determination of the particle size distribution of pulverized alumina and quartz for particle sizes from 45 to 5 µm by wet sieving.

1.2 This standard does not purport to address the safety concerns associated with its use. It is the responsibility of...

1.1 This practice covers the determination of the particle concentration, by number, and the size distribution of airborne particles in dust-controlled areas and clean rooms, for particles in the size range of approximately 0.01 to 5.0 [mu]m. Particle concentrations not exceeding 3.5 X 106 partic...

1.1 This test method is used to determine the amount and particle size distribution curve of particles with diameter 10⁶ micrometers or smaller resulting from the attrition of granular pesticides.

1.2 This standard does not purport to address all of the safety concerns, if any...

1.1 This test method covers determination of the particle size distribution of advanced ceramic powders specifically silicon nitride and carbides, in the range of 0.1 to 20 µm, having a median particle diameter from 0.5 to 5.0 µm.

1.2 The procedure described in this test method may...
