Historical Standard: ASTM D1366-86(2003) Standard Practice for Reporting Particle Size Characteristics of Pigments
SUPERSEDED (see Active link, below)
ASTM D1366
1. Scope
1.1 This practice for reporting the fineness characteristics of pigments is designed to apply in most cases where well-known methods for determining these particle size characteristics in the subsieve range are employed, such as microscopic, sedimentation, and turbidimetric methods; and partially to absorption and permeability methods.
1.2 Laminar, plate-like pigments and composite pigments having a definite bimodal distribution are not considered within the scope of this practice.
1.3 ParametersThe fineness characteristics are reported in the following three parameters:
1.3.1 Particle Size Parameter .
1.3.2 Coarseness ParameterA parameter descriptive of the coarseness character of the pigment, making use of a limiting value in the subsieve range similar to that used in the sieve ranges.
1.3.3 Dispersion Parameter -A parameter descriptive of the uniformity of the particle size distribution.
1.4 This standard does not purport to address 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.
