EN ISO 6507-3 Metallic Materials - Vickers Hardness Test - Part 3: Standard Test Method for Calibration of Reference Blocks

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO 6507-3 testing. EN ISO 6507-3 specifies a method for the calibration of reference blocks to be used for indirect verification of Vickers hardness testers, as specified in EN ISO 6507-2.

The block will be specially manufactured for use as a hardness reference block using a manufacturing process that will ensure the required homogeneity, stability of the structure, homogeneity of surface hardness and time stability in hardness.

The criteria set out in this document for the performance of the calibration machine have been developed and improved over a considerable period of time. When determining a specific tolerance that the machine must meet, the uncertainty associated with the use of measuring equipment or reference standards is included in this tolerance and thus reduces the tolerance, for example, with measurement uncertainty. This applies to all measurements made during direct verification of the calibration machine.

Each test force should be verified at three different positions of the piston, spaced in approximately equal increments covering the range of motion used during the test. In each position, the force shall be measured three times with an elastic proving device or other method with the same or better accuracy, according to ISO 376, class 0,5 or better.
