Shore Hardness Tester test force calibrating technology research

The Shore Hardness Tester is a testing instrument used to evaluate the hardness of rubber, resin, plastic products and other products. Common types of Shore Hardness Testers are type A and type D. At present, the A-type Shore Hardness Tester is mostly used in CHINA. The Shore Hardness Tester needs to be calibrated before use. Certain errors, etc.) may affect the measurement results. Therefore, Ai Zhaochun, Liu Hanye, Kang Qiang, Li Xinghua, and Liu Xinchen conducted a new method research on the calibration method of the test force of the A-type Shore Hardness Tester. The use of variable arm lever balance technology to make up for the shortcomings of existing calibration methods is introduced, and the specific operating principle process is introduced. The conclusion shows that the new method of calibration of the test force of the Shore Hardness Tester meets the requirements of the maximum allowable error of each calibration of ±75mN in the technical specification of ASTM D2240-2015, and ensures the accuracy and reliability of the test force parameters of the Hardness Tester.
