GB/T 39693.6-2020 IRHD method for the determination of apparent hardness of rubber rollers by focusing vulcanization or thermal plasticity. It clarifies the principle of this method and is suitable for the detection of rubber rollers Hardness. It puts forward requirements for the accuracy of the equipment used for testing, etc., specifies the main points of preparation of rubber rollers, and standardizes the test process, including test point selection, hardness gauge operation and reading method. According to this standard, the apparent hardness of rubber rollers can be accurately determined, providing reliable data for mass control and performance evaluation of rubber rollers, and helping the stable application of rubber rollers in various industries.
