JIS K5107-1965 is a Japanese industrial standard that specifies mass requirements and test methods for carbon black used as a pigment. The standard details the physical and chemical properties of carbon black, including Color, tinctorial strength, hiding power, dispersibility, oilabsorption value, moisture content, and strong heat residue. As an important inorganic pigment, carbon black is widely used in industries such as Coatings, inks, plastics, and rubber, providing a stable black effect and good physical performance. JIS K5107-1965 was developed to ensure the quality and conformity of black carbon pigments to meet the needs of industrial applications, and although the standard was abolished in 2013, it provided important technical guidance for the relevant industries during its valid period.
