Fundamentals of Rockwell Hardness Testing
2020 10 19 Selecting the Proper Scale In many instances Rockwell hardness tolerances are indicated on drawings At times however the Rockwell scale must be selected to suit a given set of circumstances Many Rockwell applications are covered by the B and C scales which are used for testing steel and copper as well as their alloys.

Rockwell Hardness Testing
The Rockwell hardness test method as defined in ASTM E 18 is the most commonly used hardness test method You should obtain a copy of this standard read and understand the standard completely before attempting a Rockwell test The Rockwell test is generally easier to perform and more accurate than other types of hardness testing methods.

Imperial Rubber
Another scale for hardness that is very common mostly to the paper industry is called the P J plastometer scale and its range is from 0 to 300 Here the scale is the inverse of the Shore A scale for hardness where 0 would be something equivalent to a bowling ball perhaps and 300 would be something very very soft and squishy.
