HR-15N. The Rockwell Hardness Test presses a steel or diamond hemisphere-conical penetrator against a test specimen and measures the resulting indentation depth as a gage of the specimen hardness. The harder the material, the higher the HR reading. The most common is the static load indentation hardness test, such as Brinell Hardness (HB), Rockwell Hardness (HRA, HRB, HRC), and Vickers Hardness (HV). These hardness values indicate the ability of a . In Rockwell hardness testing, HRA, HRB, and HRC represent three different scales: Scale A, Scale B, and Scale C. The Rockwell test is a common indentation hardness test. All three scales begin with an initial .High Rockwell hardness numbers represent hard materials and low numbers soft materials. d 2 www.wilsoninstruments.com Fundamentals of Rockwell Hardness Testing Like the Brinell, Vickers, Knoop, Scleroscope and Leeb tests - all of which fall in the general category of indentation hardness tests - the Rockwell test is a measure of the

The regular Rockwell hardness testing scales use heavier force (load) levels. For these scales, the preliminary force (minor load) level is 10 kgf and the standard total force (load) levels may be 60 kgf, 100 kgf or 150 kgf. The superficial Rockwell hardness testing scales use lighter force (load) levels, typically for use on thinner materials.

The standardized test blocks are calibrated in accordance with ASTM E18 section Annex A4 using NIST Rockwell standard reference materials (SRM) 2810, 2811, and 2812. All other scales are traceable to manufacturers hardness levels through laboratory standardizing machines.
