GB/T 14905-2020 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, and aims to evaluate the strength of the bonding between the layers. The standard specifies the principle of measuring the adhesive strength by tensile method, and specifies the technical specifications of equipment such as Tensile machine. Detailed specification of sample preparation, including the size and method of hose interception. Make clear requirements for the loading speed and test time of tensile test, and give the calculation and representation method of adhesive strength results. The standard provides a key detection basis for ensuring the mass of hoses and ensuring their safe and reliable operation under complex working conditions.
