Hardness Tester
Rockwell hardness testing method aims to determine the hardness of the material in terms of material durability of specimen by using steel ball indentors or diamond cones emphasized on the test material. Commonly used steel ball beam diameter is generally 1/16 inch and for soft material using 1/8, 1/4 and 1/2 inch diameter. The test is carried out by first providing a 10 kg minor load, and then given the major load, typically ranging from 60 to 100 kg for steel ball indentors and 150 kg for the bridge indentor. However, weights and indentors may be used in accordance with the test conditions.
