GB/T 17394.2-2022 《Metallic materials—Leeb hardness test—Part 2: Verification and calibration of hardness testers》 Related products

GB/T 17394.2-2022 inspection and calibrating of Leeb hardness testers for focused metal materials. The standard specifies inspection calibrating items, such as hardness gauge Impact energy of Impact devices, Impact velocity of Impact bodies, error of indication, Repeatability, etc. Strict requirements are placed on the accuracy of standard Hardness blocks and other equipment for calibrating, and the operation process is elaborated, including Appearance inspection, testing of different Impact directions and positions. According to this standard, it can ensure the accurate and reliable performance of Leeb hardness tester, provide guarantee for the accurate measurement of metal material Richter Hardness, and strongly support the mass detection of metal materials.
