This standard specifies the test method for determining the thermal shear failure temperature of hot-melt adhesives. It is suitable for the determination of this temperature, but not for hot-melt allergic adhesives. The standard cites documents such as GB/T 2943, which defines terms and definitions such as thermal shear failure temperature. According to the different test devices, it is divided into A method and B method. The former uses an electric thermostatic blast drying oven, and the latter is suitable for the determination under heat and humidity conditions. The test equipment includes a film making device, a hot-pressing device, and a corresponding thermostatic box to ensure the accuracy and Reliability of the test.
