Microhardness

Microhardness tests (ASTM E384) are done on material that is too thin or too small for Rockwell or Brinell hardness tests. There are two types of indenters Knoop (HK) and Vickers (HV) that are subjected to test forces that range from 1 to 1000 gf.

Microhardness is typically used for:

• Decarb Referee
• Case Depth
• Chord Method
• Hardness Surveys

Tensile Testing Metallurgical Laboratory also performs Vickers hardness (ASTM E92) of metallic materials, using applied forces of 300 gf to 10 kgf.
