Full Title

Full titles differ between systems:

IPC:

Investigating strength properties of solid materials by application of mechanical stress > Investigating hardness or rebound hardness > by performing impressions under a steady load by indentors, e.g. sphere, pyramid > the indentors being put under a minor load and a subsequent major load, i.e. Rockwell system

CPC:

Investigating strength properties of solid materials by application of mechanical stress > Investigating hardness or rebound hardness > by performing impressions under a steady load by indentors, e.g. sphere, pyramid (G01N3/54 takes precedence) > the indentors being put under a minor load and a subsequent major load, i.e. Rockwell system
