The GB/T 328.18-2007 standard is used to determine the tear performance of asphalt waterproofing membranes (nail rod method). It specifies the equipment required for testing, such as Tensile machine with nail rod device. Detailed sample preparation, including sampling position on the coil, sample shape and size. During testing, specify the specifications of the nail rod, the method of nailing, specify the tensile loading rate, test environment and other operating points, and the calculation method of tear performance indicators. According to this standard, the tear resistance of asphalt waterproofing membranes under the action of nail rods can be accurately measured, providing a key reference for product mass evaluation and engineering material selection. It is widely used in waterproofing membrane production and building waterproofing engineering.
