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

This standard is a recommended method specifically designed for determining the apparent hardness of rubber rollers. It involves using a Shore durometer to measure directly on the curved surface of the rubber roller, which is covered with vulcanized or thermoplastic rubber, rather than on a flat test piece. The method is suitable for measurements requiring moderate precision and specifies two types of Shore durometers: Type A (for conventional hardness) and Type D (for high-hardness rubber rollers).
