GB/T 39693.2-2025 《Rubber, vulcanized or thermoplastic—Determination of hardness—Part 2: Hardness between 10 IRHD and 100 IRHD》 Related products

GB/T 39693.2-2025 is the second part of the series of standards for the determination of the Hardness of vulcanized rubber or thermal plasticity rubber, which is specially aimed at the determination of the international Hardness of rubber in the range of 10 IRHD to 100 IRHD. The standard clarifies the test principle, instrument requirements, operation steps and result representation of the hardness testing. It is suitable for the conventional Hardness testing of two types of rubber. It can unify the detection method and ensure the accuracy of the data, and provide a reliable technical basis for the production quality control, performance evaluation and application scene adaptation of rubber products.
