KS B5527-1995 Shore hardness tester is a Korean national standard that specifies the technical requirements, structural design, test methods and usage specifications of the Shore hardness tester. The standard describes in detail the main components, technical parameters and their application scope of the tester, and specifies the performance calibration requirements of the equipment to ensure the accuracy and consistency of the hardness test results. In addition, the standard provides specific guidance on the operating procedures, test conditions and recording methods of the results of the tester, which is applicable to the Shore hardness determination of metals and other materials. As the core tool of Shore hardness testing, the standard provides a unified technical basis for the design, manufacture, calibration and use of the tester, and is an important reference in the field of hardness testing.
