This part of GB/T 3810 specifies the method for measuring the small color difference between single-color ceramic tiles with uniform color and smooth surface using color measuring instruments. This method adopts a maximum acceptable value as the tolerance of color difference, which depends only on the closeness of color matching, and has nothing to do with the color involved and the nature of color difference. This standard does not deal with color variations formed for artistic purposes.
