The GB/T 30789.6-2015 standard describes a method for assessing the degree of chalking of Paints coatings using the adhesive tape method. By sticking the powder on the coating surface with adhesive tape and comparing it with the background reference, the chalking grade of coatings can be accurately evaluated. The standard emphasizes the distinction between true aging degradation products and stains, especially in the case of slight chalking. This method provides a simple and effective means of chalking assessment, suitable for laboratory and field coating mass detection.
