GB/T 328.2-2007 "Test methods for building waterproof sheets - Part 2: Bitumen waterproof sheets - Appearance" specifies the inspection methods for the appearance quality of bitumen waterproof sheets. This standard involves visual inspection or the use of measuring tools to examine the overall condition of the sheet, including the tightness of the roll, the neatness of the end faces, and the presence of surface defects such as holes, cracks, lumps, bubbles, wrinkles, scars, and the uniformity of the coating material. These are fundamental requirements for evaluating the basic appearance quality.
