GB/T 39697.1-2020 specifies the Hardness requirements for rubber or plastic coated rollers. It specifies the specific numerical standards for Hardness of different types and uses of coated rollers, covering the allowable tolerance range of Hardness. This standard provides manufacturers with a manufacturing basis to ensure that the Hardness of the coated rollers produced meets the needs of the industry. At the same time, it provides inspection standards for purchasers and Quality inspection organizations. Through the detection of Hardness, it can effectively determine whether the mass of the coated rollers is up to standard, ensure its stable operation in related equipment, and promote the standardized development of the rubber or plastic coated roller industry.
