In order to test larger pieces, such as forgings, a section would need to be removed from the forging in order for it to be tested. Since this is not always feasible or even possible, ASTM International Committee A01 on Steel, Stainless Steel and Related Alloys has developed a standard for portable hardness testing. 1.5 At the time the Brinell hardness test was developed, the force levels were specified in units of kilograms-force (kgf). Although this standard specifies the unit of force in the International System of Units (SI) as the Newton (N), because of the historical precedent and continued common usage of kgf units, force values in kgf units are provided for information .

The original title of this standard was "Standard Test Method for Equotip Hardness Testing of Steel Products." 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. This standard does not purport to address all of the safety concerns, if any, associated with its use.The ASTM E8 / ASTM E8M standard describes uniaxial tensile testing of metals at room temperature and the determination of characteristic values including yield strength, yield point, yield point elongation, tensile strength, strain at break and reduction of area.. The values can be used to make predictions about the strength and toughness of the material.

A tension test shall be used to determine the required tensile properties such as tensile strength, yield strength, and elongation. Materials shall undergo: (1) an impact test for non-fracture critical and fracture critical members; and (2) a Brinell hardness test for Grades 100 and 100W. Atmospheric corrosion resistance shall also be determined.
1.3 Conversion Table 3 presents data on the relationship among Brinell hardness, Vickers hardness, Rockwell hardness, Rockwell superficial hardness, and Knoop hardness of nickel and high-nickel alloys (nickel content over 50 %). These hardness conversion relationships are intended to apply particularly to the following: nickel-aluminum-silicon specimens finished . 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). 1.1 These test methods 2 cover procedures and definitions for the mechanical testing of steels, stainless steels, and related alloys.
