Application Summary AI generated
This standard specifies a method for comparing the contrast ratio, or hiding power, of white pigments used in paints and coatings. It is applied in quality control and product development within the paint industry to evaluate how effectively a white pigment obscures the surface beneath it. The test involves measuring the reflectance of a pigment film over black and white substrates to determine its opacity.
