GB/T 13477.8-2017 "Test method for building sealants—Part 8：Determination of tensile properties"

GB/T 13477.8-2017 focuses on the determination of tensile adhesion of building sealing materials. The standard specifies the technical specifications of the test equipment, such as the Tensile Testing Machine, and specifies the bonding preparatory details of the sealing material specimen and the substrate. Under the specified tensile rate and loading method, the specimen is applied with tensile force, and the key indicators such as tensile strength and fracture elongation of the sealing material are accurately measured. At the same time, the bonding interface condition is observed. Through these measurements, the bonding performance of the sealing material under the action of tensile force is evaluated, which provides a scientific and reliable mass detection basis for the application of building sealing materials in tensile scenes and guarantees the mass of sealing engineering.
