GB/T 14905-2009 is a standard for testing the adhesive strength between the layers of rubber and plastic hoses. It is suitable for all kinds of rubber and plastic hose products. It clarifies the testing principle, introduces the required equipment such as Tensile machine, and standardizes the preparation process of the sample, such as cutting the appropriate length and width of the hose fragment. The tensile test steps are described in detail, including the tensile speed, loading method, etc., and the calculation and representation method of the adhesive strength results are also specified. The standard provides a unified specification for evaluating the bonding mass between the layers of the hose, which is of great significance to ensure the safety and life of the hose under different working conditions.
