Standard Vickers Test Blocks

Calibrated as per ISO 6507-3, IS 1501 (Part 3) and/or ASTM E92 (Annex A4)
Calibrated at Fmi Calibration Laboratory, NABL accredited (ISO/IEC 17025:2017)
Specially curated high-quality steel, aluminium and brass material
Specially designed heat treatment and cryogenic treatment to achieve maximum long term hardness stability, consistency and repeatability
Mirror surface finish by grinding, lapping and diamond polishing
Calibration traceability: Vickers test blocks are calibrated using a standardising hardness testing machine which is directly and indirectly calibrated as per the requirements of ISO 6507-3 and ASTM E92 annex A2; using instruments traceable to SI system of units realised at NPL-India, NPL-UK, IMGC, NIST or PTB either directly or through NABL/UKAS/NVLAP/A2LA/DAkkS accredited laboratories.
LASER marking on the surface of hardness value, Serial number, lab logo and reference indent location.
Optional hexagonal LASER grid marking
Available in shapes: Φ50 mm and Φ64 mm
Recommended key usage: Perform Indirect verification/calibration of hardness testers as per ISO 6507-2, IS 1501 (Part 2) or ASTM E92 annex A1, periodic quality control checks/intermediate checks, daily verifications, etc.
