GB/T 13452.3-1992 "Paints and varnishes - Determination of hiding power - Part 1: Kubelka-Munk method for white and light-coloured paints" specifies a method for determining hiding power based on the Kubelka-Munk theory, applicable to white and light-coloured paints. The hiding power value is calculated by measuring the reflectance of the paint film on black and white substrates. The test requires instruments such as a spectrophotometer, a film applicator, black and white standard substrates, and a film thickness gauge, providing a standard for the scientific evaluation of the hiding performance of coatings.
