It is measured quantitatively, usually by noting the extent or depth of hardening of a standard size and shape of test specimen in a standardized quench. In the end-quench test the depth of hardening is the distance along the specimen from the sstm end which correlates to a given hardness level.

It is measured quantitatively, usually by noting the extent or depth of hardening of a standard size and shape of test specimen in a standardized quench. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The two test methods include the quantitative end-quench or Jominy Test and a method for calculating asstm hardenability of steel from the chemical composition based on the original work by M.
