The ASTM D5326-22 Standard Test Method for Color Rendering of Colored Latex paints provides a standardized test method for the color rendering performance of colored latex paints. This standard describes methods for measuring the color change of colored latex paints under different conditions. It is designed to evaluate the color change of latex paints after color matching and during drying. This test provides an accurate understanding of the Stability of Coating colors and the conformity of colors during use. The standard covers the entire process from Spreader, drying to Color Determination, and provides an important reference for Coating manufacturers, quality control personnel and users to ensure that the color performance of the final product meets the expected standards. This method is essential to ensure the color mass of colored latex paints, especially in large-scale production and batch applications.
