Brinell Test Block 60 to 140 (Specify Hardness No.)

Brinell Test Blocks are made of only the highest quality steel and aluminum. The impressions in the test bars are made with a Brinell machine whose accuracy is maintained by a proving ring traceable to the National Institute of Standards and Technology (NIST). Before certifying the Test Blocks, we double-check the impressions with an electronic microscope accurate to .01mm. Each Test Block exceeds all ASTM-E10 Standards to provide you with the highest degree of accuracy.
