scope:

This test method covers the determination of the particle size distribution (PSD) of hydraulic cement and related compounds by means of the laser diffraction technique, reported as volume percent of particulate materials.1 This test method applies to analyses with both non-aqueous dispersions and gaseous dispersions. This test method is applicable to the measurement of particulate materials in the size range of 0.4 to 2000 μm.

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

This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns associated with its use. It is the responsibility of the user of this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
