色素炭黑 黑度的测定
Application Summary AI generated
This standard specifies the test method for determining the blackness of colour carbon black, which is a key quality indicator for pigment-grade carbon blacks used in plastics, inks, and coatings. It is applied in quality control and product specification verification within the rubber and plastic industries, particularly for raw material inspection and batch consistency testing. The method involves comparing the reflectance of a carbon black dispersion against a standard reference to quantify its tinting strength.
