Hardness Testing

Indentation hardness:

measures the resistance of a sample to permanent plastic deformation due to a constant compression load from a sharp object; they are primarily used in engineering and metallurgy fields. The tests work on the basic premise of measuring the critical dimensions of an indentation left by a specifically dimensioned and loaded indenter.

Methods of measuring Indentation Hardness are as follows:

• Brinell Hardness Testing

• Rockwell Testing

• Vickers Hardness Testing

Rebound Hardness:

A method of determining rebound hardness is the Shore Scleroscope
