This standard specifies the technical requirements for the determination of the density of paints, varnishes and related products using the pressure cup method. This method is suitable for products where bubbles may be present (such as latex paint), but not for coatings containing coarse particles. This edition changes the density unit from g/ml to g/cm3 compared to previous versions and updates the reference materials. In addition, the standard specifies the key steps in the determination process to ensure the accuracy of the measurement results.
