GB/T 18449.2-2012 Focus on metal materials - inspection and calibrating of Knoop hardness gauge. This standard specifies the inspection process of hardness gauge before it is put into use, regular use and after maintenance. Strict testing requirements are put forward for key components such as the loading system of hardness gauge, the accuracy and shape of the indenter, and the measurement device. By implementing these calibrating procedures, the hardness gauge can ensure accurate measurement of Knoop Hardness of metal materials, and provide reliable and consistent data support for performance inspection and quality control of metal materials.
