Abstract

THE Rockwell hardness number is based on the additional depth to which the penetrator is driven by a heavy load beyond the depth to which the same penetrator has been driven by a definite light load. A minor load is applied and often, without moving the specimen, a major load is applied. The major load is then removed leaving the minor load on, and the hardness number is indicated on the dial.
