The ISO 8780-1:1990 standard introduces the basic concepts and methods for evaluating the dispersion properties of pigments and fillers. The standard, as part of the ISO 8780 series, covers the introduction to a variety of dispersion methods, providing a framework for subsequent sections. These methods include dispersion using equipment such as vibratory vibrators, high-speed impeller mills, bead mills, automatic Grinders and three-roll mills. The standard defines key terms such as grinding stock, degree of dispersion and dispersion, and highlights the effect of the effectiveness of dispersion on the performance of pigments in gluing agent systems. ISO 8780-1 provides the basis for the standardization of relevant dispersion test methods, ensuring conformity of the dispersion process and Reliability of results.
