This standard specifies in detail the technical requirements, inspection methods, inspection rules, marks and Encasement of the D-type Shore hardness gauge. It is applicable to the D-type Shore hardness gauge used to determine metal Shore Hardness, ensuring the Stability and accuracy of the hardness gauge under normal working conditions. A number of national standards are cited, including general technical requirements for testing machines and metal Shore Hardness test methods, to ensure that the mass and performance of the hardness gauge meet the standard requirements. In the technical requirements part, the working conditions of the hardness gauge, the requirements of the frame and the test bench, and the design requirements of the lifting and operating mechanism are specified to ensure the Reliability and convenience of the hardness gauge.
