Shore D high-hardness rubber Hardness Tester is an instrument for measuring the hardness of high-hardness rubber materials with Shore A hardness greater than 90 HA (degrees), and can also measure the hardness of engineering plastics, glass steel and other similar high-hardness materials. It implements the American Society for Testing and Materials standard ASTM D 2240-05 and the Japanese national standard JIS K 6253-2006, and implements GB/T2411-2008. This standard is equivalent to ISO 868: 2003 "Plastic and Hard Rubber - Determination of Indentation Hardness Using a Durometer ( Shore hardness)" (English version). This standard is equivalent to the translation of ISO 868:2003, and is completely consistent in technical content. And refer to the implementation of my country's GB/T 531.1-2008, "Vulcanized rubber or thermoplastic rubber indentation hardness test method part one: Shore durometer method (Shore hardness)", the national standard is equivalent to the international standard ISO 7619-1-2004, at the same time Also refer to the relevant regulations in JJG 304-2003 "Shore Hardness Tester Verification Regulations".
The Hardness Tester is installed on the same type of constant load measuring frame that is produced as a complete set, and can measure the hardness of hard rubber test pieces in the laboratory.
It is suitable for determining the hardness of Shore A rubber greater than 90° in the laboratory, and can also determine the hardness value of similar high-hardness materials such as engineering plastics and glass fiber reinforced plastics.
