Wilson Vickers Knoop Hardness Test Blocks

Wilson Knoop and Vickers hardness test blocks set the standard for the industry and are made from the highest quality material to insure the most uniform and repeatable blocks available. A comprehensive variety of scales and test blocks are available to meet the wide ranges and hardness scales associated with Rockwell®, Brinell, Knoop and Vickers testing. All Wilson Vickers and Knoop test blocks are calibrated in the Wilson Hardness Calibration Laboratory in Binghamton, NY. 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.

100% inspection to ensure that every single Knoop and Vickers test block meets the physical requirements of ASTM (thickness, flatness, parallelism, surface roughness).

We work directly with the steel and brass mills to specify the chemical composition

Our 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)
