Wilson Vickers Knoop Hardness Test Blocks

Wilson Brinell hardness test blocks set the standard for the industry and are made from the highest quality material to insure the most uniform and repeatable Brinell test blocks available

A comprehensive variety of scales and blocks are available to meet the wide ranges and hardness scales associated with Rockwell®, Brinell, Knoop and Vickers testing

All Wilson Brinell test blocks are calibrated in the Wilson Hardness Calibration Laboratory

The Wilson lab is accredited to ISO/IEC 17025 by A2LA and the testers used in the calibration process undergo a stringent monitoring process using NIST traceable devices

  • Buehler work directly with the steel and brass mills to specify the chemical composition
  • Buehler machining processes (grinding, lapping, polishing) are all done in house, at the site of calibration.
  • 100% inspection to ensure that every single test block meets the physical requirements of ASTM (thickness, flatness, parallelism, surface roughness)
