load, the indentation hardness test can be divided into macro (also called gen-eral or universal) and micro hardness testing. For macro hardness testing, the test loads are 1 kgf (9.81 N) or larger, while micro hardness testing covers the load range from 1 gf to 1 kgf. The required surface condition depends on the type of test and load used. For
