Introduction

GB/T 5211 is a series of standards for general test methods for pigments and extender pigments. Due to historical reasons, the names of some of the standards formulated earlier The unified guiding element "General Test Methods for Pigments and Extender Pigments" is not used. In addition, there are a few common test methods for pigments and extender pigments. The independent number of the standard is not included in the various parts of the national standard GB/T 5211.It will be gradually processed in recent years and in the future formulation or revision work. Smoothly, standardize the format of the standard number and standard name, and improve the standard system. GB/T 5211 "General Test Methods for Pigments and Extender Pigments" The correspondence between the various parts to be formulated or revised and the current standards are shown in Table 1.
