GB/T 328.17-2007 "Test Methods for Building Waterproofing Sheets - Part 17: Bituminous Waterproofing Sheets - Adhesion of Mineral Granules" specifies the method for determining the adhesion of mineral granules or flakes on the surface of bituminous waterproofing sheets (such as shale-faced or colored sand-faced sheets). This standard evaluates the ease with which mineral granules detach from the coating layer of the sheets under dry, wet, or water-immersed conditions through specific procedures (such as brushing-off or immersion methods).
