ASTM E384 is the standard test method for Knoop and Vickers hardness testing. Test loads are as low as 1 gram and as high as 1,000 grams, but are typically in the range of 100 to 500 grams. The Vickers indenter usually produces a geometrically similar indentation at . The Vickers Hardness test (ISO 6507) is used to characterize hardness of various solid materials (metals, ceramics, etc.). A diamond pyramid is pressed against the solid with a certain normal load and the hardness is calculated based on the imprint left on the surface. . Standard Hardness Conversion for metals acc. ASTM E 140 – 97 .
ASTM E384: This standard is for hardness testing on a micro-scale, and therefore includes the Vickers and Knoop hardness tests. ISO 6506: This standard mirrors ASTM E10, as it contains the standard method for measuring the Brinell hardness of metals.
