The GB/T 1770-2008 standard specifies the method for determining the sanding performance of films and putty films under specified loads. The sanding performance of films is assessed by observing the change of the film surface and the degree of difficulty of sanding by performing a specified number of sandings on the specimen. The standard provides an empirical test method to help evaluate the abrasion resistance of films and putty films in actual use. It is suitable for performance testing of various coatings and putties.
