ISO 787-5:1980 "General test methods for pigments and fillers, Part 5: Determination of oil absorption value" specifies a general method for determining the oil absorption value of a sample of pigments or fillers. Oil absorption value refers to the volume or mass of refined flaxseed oil absorbed by the sample under specified conditions and is used to evaluate the oil absorption capacity of a material. This test method is essential for determining the physical performance and application characteristics of pigments and fillers. During the implementation of the standard, it is necessary to compare with the Miscellaneous method provided in the international standard and note any specific modification requirements in the relevant standard. This standard provides a uniform test method for the industry to ensure reliable evaluation of pigment and filler performance.
