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.
