BS EN 1 2310-2 - 2010 "Determination of tear resistance of waterproof flexible panels (nail bars). Plastics and rubber sheets for roof waterproofing", for roof waterproofing plastics and rubber sheets, the test method for determining the tear resistance of the nail rod method is standardized. The standard specifies the sample preparation, test equipment requirements and operation procedures. By simulating the nail rod penetration process, the ability of the thin plate to resist tearing is quantified. It provides a scientific basis for evaluating the mass and durability of roof waterproof flexible panels, and ensures that the performance of roof waterproofing engineering materials is up to standard.
