Test Blocks

Rockwell Regular Test Blocks – With Certification

Made to order. Specify hardness range (3 below and 3 above target) at check out.  The XX represents a variable part number that follows the following example:  A C scale 55 hardness C Diamond 150 Kg Steel  would  have the following part number RC1052-58.

We offer an extensive Rockwell Hardness Test Block selection All of our Rockwell Hardness Test Blocks come with Certification. All the blocks are calibrated and accredited to ISO guide 25 and will meet automotive and aerospace standards. The HRC test blocks are calibrated on the new NIST level.

Brinell Hardness Test Blocks – With Certification

Made to order. Specify hardness range from 100-1000.

All of our Brinell Test Blocks come certified to applicable standards. We adhere to a strict procedure for the calibration of these blocks, and the accuracy of the tester is maintained using a proving ring and load cell both traceable to N.I.S.T. The readings themselves are done using a stage micrometer also calibrated and traceable to N.I.S.T.
