The ISO 6504-3-2006 standard describes in detail a method for measuring the hiding power of light-colored paints, particularly for white or light-colored paints with a tristimulus value greater than 25. The method assesses opacity by measuring the contrast ratio of the paint applied to a black-and-white chart or a colorless transparent polyester film at a fixed expansion rate. This standard is suitable for evaluating the covering effect of coatings and is important for quality control in the coatings industry.
