ISO 6507-2 – Vickers Hardness: Verification and Calibration of Testing Machines

ISO 6507-2 is the ISO standard that specifies how testing machines and their diagonal measuring systems are verified and calibrated for determining Vickers hardness in accordance with ISO 6507-1. The current edition is ISO 6507-2:2018, which ISO confirmed in its last review.

A direct method covers the testing machine, the indenter and the diagonal length measuring system. An indirect method uses reference blocks for an overall check of the machine. If a machine is also used for other hardness methods, it has to be verified separately for each one. The standard also applies to portable hardness testing machines, but not to machines based on different measuring principles, such as the ultrasonic contact impedance method. Labs schedule these checks around their quality system and customer requirements.

Vickers testers such as the Macro Vickers hardness tester are used for Vickers testing where machine verification to ISO 6507-2 is part of the lab routine. If you need help matching ISO 6507-2 requirements to your parts or setup, contact our team.
