ASTM E18 - 14 Standard Test Methods for Rockwell

1.4 UnitsAt the time the Rockwell hardness test was developed, the force levels were specified in units of kilograms-force (kgf) and the indenter ball diameters were specified in units of inches (in.).This standard specifies the units of force and length in the International System of Units (SI); that is, force in Newtons (N) and length in millimeters (mm). ASTM E18-15 - Standard Test Methods for Rockwell 1.1 These test methods cover the determination of the Rockwell hardness and the Rockwell superficial hardness of metallic materials by the Rockwell indentation hardness principle. This standard provides the requirements for Rockwell hardness machines and the procedures for performing Rockwell

Rockwell Hardness Guide What it is, How to Measure, & More

The Rockwell brothers were metallurgists working in a Connecticut ball bearing factory back in the early 1900s. They recognized the need for accurately and quickly testing metal strength in bearing races. They also required a clear method for reporting strength test results. Stanley Rockwell patented the Rockwell testing method in 1914. Standard Rockwell Test Block WESTport Corp.Standard Rockwell Test Block.
