The ASTM D1210-05 (2022) standard describes a test method for determining the dispersion fineness of pigment carrier systems using Hegman gauges. This method is used to evaluate the Carr Dispersibility of pigments in Liquid Coatings and Miscellaneous Supports, i.e. whether the pigment has been sufficiently ground. Test results are critical to the smoothness of the film and the mass of the final product. The standard provides an effective evaluation tool to help manufacturers ensure uniform dispersion of pigments, thereby improving product conformity and performance.
