Hardness Test Blocks

These Brinell hardness test blocks are supplied with the industry’s most comprehensive certificate of calibration, traceable to National Institute of Standards and Technology (NIST). Designed with a test surface measuring 6 x 4.5 inches, the number of indents per block has been increased from 35 to 80 on average, providing 128% more tests on a single test block. The larger size and increased life will result in fewer orders, resulting in lower administrative costs for consumers. An engraved indent placement pattern ensures appropriate indent spacing is maintained, eliminating erroneous readings. These test blocks are both ASTM E10 and ISO 6506 compliant.
