Shore durometers are more and more widely used in the rubber product industry, and can also be used in industries such as paper, wood, and textiles. In order to better use the Shore Hardness Tester, He Guanglin and Li Chuang made an analysis of the influence of various factors on the use and verification of the Shore Hardness Tester in the paper "Problems in the Use and Verification of the Shore Hardness Tester" and corresponding measures. The problems in the use of the Shore Hardness Tester include: the use of brackets, the test speed, the test sample, the test range, the rounding off of the Hardness Tester, and the use of the vibration device; the problems in the verification include: the verification of the indenter, the verification of the extension, Verification of measuring indicating device, verification of spring test force, verification measuring point, main standard equipment used, compliance verification of indication error, etc.
In addition, the verification method is studied by using the test force of Type A Shore Hardness Tester, and finally it is concluded that the force value of Type A Shore Hardness Tester is verified by the division method, the measuring instruments used, the measurement method adopted, and the Limitations of the maximum permissible error are all practicable.
