GB/T 21868.1-2008 "Pigments and extenders — Methods of dispersion for assessment of dispersion characteristics — Part 1: General principles" specifies the general principles and requirements for various dispersion methods used in assessing the dispersibility of pigments. It applies to the implementation of dispersion methods in subsequent parts. The standard clarifies common requirements such as dispersion media, equipment calibration, and sample preparation, without specifying particular testing instruments. It provides a foundational framework for standardized operations in dispersibility assessment, ensuring comparability of results across different dispersion methods.
