NewAge Testing Instruments sells three types of hardness test blocks: Standard test blocks that match the historical American test values, NewAge/Yamamoto test blocks that match the Japanese international standard, and test blocks traceable to NIST that match newer American standard.

* Nominal values (also called face values) are used for convenience because the manufacturer cannot exactly predict or control the actual values. For the purposes of hardness testing, the user does not need to calibrate using a specific value. Usually when testing in a certain scale, using a value that is at the low, medium and high range of a particular scale is advised.
