Zwick Roell is supplying hardness test blocks in different materials for use in calibration and test equipment verification.
The important role of hardness test blocks is sometimes overlooked and not always fully understood, but daily verifications via test blocks can quickly validate hardness testing equipment performance and the compliance with standards, as well as the accuracy of the total system.
Zwick Roell Indentec offers a wide range of hardness test blocks for all standard test methods, available in various materials including steel and carbide, and are supplied complete with UKAS accredited certification.
Standardised test blocks as reference materials are an integral part of hardness testing. They ensure accuracy, integrity and traceability of the hardness testing process. Typically they are used to both verify hardness test machine performance and to provide a means for performing indirect calibrations. The useful life of a standardised test block is determined by the density of indentations on the surface and once the recommended densities are reached the standardised test block must be replaced.
Verification testing with standardised test blocks should be performed throughout the total working range of the hardness test machine using multiple standardised test blocks with appropriate hardness values certified at relevant load forces. It should be noted that standardised test blocks should only employ the top surface of the block.
In additional to an extensive range of commonly used blocks, Zwick Roell Indentec can also supply Brinell test blocks with scales 250kgf to 3000kgf, complete with UKAS accreditation to ISO 6506-3: 2014 & ASTM E10. All hardness test blocks supplied by Zwick Roell Indentec are supplied in a hardwearing plastic storage case with foam inlay, to provide adequate protection for the block.
