Rockwell Hardness Measurment of Metallic Materials

The Rockwell hardness test continues to be applied as a tool for assessing the properties of a

product while the tolerances on the acceptable material hardness have become tighter and

tighter.


Adhering to “good practice” procedures when performing Rockwell hardness measurements and

calibrations is a beneficial step to reducing measurement errors. The purpose of this Guide is to

explain the causes of variability in Rockwell hardness test results and to supplement the

information given in test method standards with good practice recommendations. Although this

Guide is directed more towards the users of Rockwell hardness having the greatest concern for

accuracy in their measurements, much of the information given is also applicable for users that

only require test results to be within wide tolerance bands, where high accuracy is not as critical.
