Rockwell Hardness Test:

The specimen is subjected to a major load for about 15 seconds after the initial load. ASTM says 13 scales for testing of wide range of materials. These scales are A, B, C... etc. B-scale is taken for soft steel and Aluminum alloys while C scale is used for hard steel. B scale uses ball of 1/16" while cone indenter is used for c scale.
