Buehler is introducing a Quick Ship program for the popular Wilson certified Rockwell hardness test blocks.  For ultimate accuracy and performance in tester verification, Buehler has calibration sets available for most Rockwell scales.   

Buehler is launching a Quick Ship Program for a selection of the most commonly used Rockwell test blocks in North America. The following test blocks are available for next day shipment in North America:

  • HRB Scale: 40HRBW, 50HRBW, 60HRBW, 70HRBW, 80HRBW, 95HRBW
  • HRC Scale: 25HRC, 30HRC, 35HRC, 40HRC, 45HRC, 50HRC, 55HRC, 60HRC, 63HRC
  • HR15N Scale: 72HR15N, 83HR15N, 91HR15N
  • HR15T Scale: 74HR15T, 87HR15T

Buehler’s Wilson hardness test blocks utilize the highest quality material to insure the most uniform and repeatable test blocks available.  A comprehensive variety of scales and hardness test blocks are available to meet the wide ranges and hardness scales associated with Rockwell®, Brinell, Knoop and Vickers testing.  

The complete line of Wilson Rockwell, Wilson Brinell and Wilson Vickers / Knoop Test Blocks for hardness testing is available within the hardness section of the Buehler website. To assist customers in the selection, process Buehler has also released a Test Block Application Guide with valuable information about the Wilson line of test blocks and important information about proper usage of test blocks. 

All Wilson hardness 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 test block meets the physical requirements of ASTM (thickness, flatness, parallelism, surface roughness).
