Wilson Brinell 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 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.
