标准简介
This document describes the methods for determining the particle size distribution of powders by sonic sieving and by small angle X-ray scattering. This document is applicable to the determination of the particle size distribution of powders, with the following ranges of results: particle sizes not less than 20 μm for the sonic sieving method and not greater than 300 nm for the small angle X-ray scattering method. This document is not applicable to powders of markedly non-equiaxed shape, such as flake or acicular powders.
