Rockwell testing falls into two categories: Regular Rockwell testing (e.g., C and B scales) and Rockwell superficial testing (e.g., 30 N and 30 T scales). High Rockwell hardness numbers represent hard materials and low numbers soft materials. d 2 www.wilsoninstruments.com Fundamentals of Rockwell Hardness TestingSet includes six files and a chart to convert to Vickers scale. It is an economical way to determine the hardness of steel on the Rockwell C-scale.Handles are marked with Rockwell hardness values. If a file can scratch your material, then your material is softer than the file. If a file cannot scratch your material, then your material is harder than the file.

Verification should be performed by an accredited verifying agency and the report should follow and reference ASTM E18 Rockwell test method. Hardness testing is an important and useful tool in materials testing, quality control and acceptance, and performance of materials. . Rockwell Hardness Testing Calibration Kits; Rockwell Hardness Testing Theory. Rockwell hardness testing has several indenter types which in turn require separate major loads (kg). Figure 1 reflects common Rockwell scales used and their corresponding major loads. Figure 1. When Rockwell hardness testing, a minor load of 10kg is applied to the indenter used on the material being tested.[1] Sawla A., Uncertainty of measurement in the verification and calibration of the force measuring systems of testing machines.Proceedings of the Asia-Pacific symposium on measurement of force, mass and torque (APMF), Tsukuba, Japan, November 2000 [2] Wehrstedt A., Patkovszky I., News in the field of standardization about verification and calibration of .
