The Brinell hardness HBW results from the quotient of the applied test force F (in newtons N) and the surface area of the residual indentation on the specimen (the projection of the indentation) after removal of the test force (see Brinell formula).To calculate the surface area of the residual ball indentation, the arithmetic mean d of the two perpendicular diagonals d1 and d2 (in mm) is .
If a testing machine is also to be used for other methods of hardness testing, it shall be verified independently for each method. ISO 6507-2:2018 is also applicable to portable hardness testing machines but not applicable to hardness testing machines based on different measurement principles, e.g. ultrasonic impedance method. For instance, material testing standards like ISO 148-1 (Charpy impact testing) and ISO 6508 (Rockwell hardness testing) allow industries to have reliable methods to assess material toughness and hardness.

ISO 48-2 also specifies modified procedures for use on curved test pieces, with the result being expressed as apparent hardness. A dead-load method for very soft materials using the very low rubber hardness scale (VLRH) is specifiedISO 6506-1:2014 specifies the method for the Brinell hardness test for metallic materials. It is applicable to both fixed location and portable hardness testing machines. For some specific materials and/or products, particular International Standards exist (e.g. ISO 4498) and make reference to this International Standard.
1.5 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).
