ASTM E18 – Standard Test Methods for Rockwell Hardness of Metallic Materials. Scope. ASTM E18 is a standard test method used to determine the Rockwell hardness of metallic materials. Rockwell hardness is a measure of a material’s resistance to indentation, similar to Brinell hardness. However, the Rockwell test uses a diamond indenter or a .This standard is issued under the fixed designation E18; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of . Designation: E18 − 16 Standard Test Methods for Rockwell Hardness of Metallic Materials 1,2.
3.1.7.3 portable Rockwell hardness testing machine—a Rockwell hardness testing machine that is designed to be transported, carried, set up, and operated by the users, and that measures Rockwell hardness by the Rockwell indentation hardness test principle. 3.1.7.4 movable Rockwell hardness testing machine—a Rockwell hardness testing machine .The Rockwell hardness test method, as defined in ASTM E-18, is the most commonly used hardness test method. You should obtain a copy of this standard, read and understand the standard completely before attempting a Rockwell test. The Rockwell test is generally easier to perform, and more accurate than other types of hardness testing methods .1.4 Units — At 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). This standard provides the requirements for Rockwell hardness machines and the procedures for performing Rock-well hardness tests. 1.2 This standard includes additional requirements in annexes:

A Rockwell hardness tester. The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1] There are different scales, denoted by a single letter, that use different loads or indenters.Rockwell hardness testing and ASTM E18 standards. Hardness is defined as a material’s resistance to permanent indentation. Current Rockwell hardness test methods are specified in ASTM E-18 and anyone wishing to perform a Rockwell Hardness test should become familiar with this test standard.
