GB/T 23988-2009 "Determination of wear resistance of coatings by falling sand method" specifies the method for determining the wear resistance of coating films using the falling sand method, which is applicable to the testing of wear resistance for various types of coating films. The principle involves allowing standard sand particles to fall freely from a fixed height to impact the coating film, and evaluating the wear resistance based on the amount of sand required to cause damage to the film. The testing requires instruments such as a falling sand wear tester, standard sand, a balance, and a coating thickness gauge, providing a unified technical basis for assessing the wear resistance of coating films.
