    1. Scope

    1.1 This test method covers the determination of the particle size distribution by light scattering, reported as volume percent, of particulate materials including metals and compounds.

    1.2 This test method applies to analyses with both aqueous and nonaqueous dispersions. In addition, analysis can be performed with a gaseous dispersion for materials that are hygroscopic or react with a liquid carrier.

    1.3 This test method is applicable to the measurement of particulate materials in the range of 0.4 to 2000 m, or a subset of that range, as applicable to the particle size distribution being measured.

    1.4 The values stated in SI units are to be regarded as the standard.

    1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
