DESCRIPTION : The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload.[1] There are different scales, denoted by a single letter, that use different loads or indenters. The result is a dimensionless number noted as HRA, HRB, HRC, etc., where the last letter is the respective Rockwell scale RANGE OF EXPERIMENTS : 1. To Measure the hardness of given specimen using Rockwell hardness tester. TECHNICAL DESCRIPTION : Test loads 60, 100 & 150 kgf for trsts on Rockwell A, B, C, scale. Automatic Zero setting dial gauge. Load selection just by dialing externally.
