GB/T 39693.7-2022 《Rubber,vulcanized or thermoplastic—Determination of hardness—Part 7:Apparent hardness of rubber-covered rollers by Shore-type durometer method》 Related products

GB/T 39693.7-2022 is the seventh part of the series of standards for the determination of the Hardness of vulcanized rubber or thermal plasticity rubber, focusing on the determination of the apparent hardness of rubber rollers. The standard specifies the scope of application, based on the Shore Hardness method, specifies the equipment, sample requirements, test procedures and result calculation in detail, and stipulates the test environment, operation points and other key elements. It provides a unified technical standard for the scientific and accurate determination of the Hardness of rubber rollers, and ensures the standardization and accuracy of the mass detection of rubber rollers.
