"GB/T 9270-1988 Determination of the contrast ratio of light Paints (polyester film method) " is a standard coordinated by the Technical Committee for Coatings and Pigment Standardization of the Communist Party of China. The standard specifies the method for measuring the contrast ratio of white or light-colored films by polyester film method, that is, the method for evaluating their opacity. This measurement method helps to determine the hiding power and practical application effect of coatings.
