GB/T 9273-1988 "Test for no-marking of paint film" specifies the method for determining the no-marking properties of paint films, applicable to various types of color paints and varnish films. Using a certain weight of degreased cotton or filter paper, the film is contacted under specified pressure for a certain period, and whether marks are left on the film is observed. The test requires equipment such as weights, timers, degreased cotton, filter paper, and sample holders to visually evaluate the indentation resistance of the paint film after drying.
