1 Scope This standard specifies a method for determining the hardenability of steel by end quenching (Jominy test) by using a test piece 25mm in diameter and 100mm long. Note: By agreement and for a defined field of application, the test described in this standard may be replaced by the calculation of the Jominy curve in accordance with an accepted mathematical model (see Annex C). In case of dispute, the test shall be carried out. 2 Normative References The following normative documents contain provisions which, through reference in this standard, constitute provisions of this standard. For dated reference, subsequent amendments to, or revisions of, any of these publications do not apply. However, all parties coming to an agreement according to this standard are encouraged to study whether the latest editions of these documents are applicable. For undated references, the latest edition of the normative document referred to applies.
