La présente Norme internationale spécifie la méthode de détermination de la trempabilité de l'acier par trempe en bout (essai Jominy), à l'aide d'une éprouvette de 25 mm de diamètre et 100 mm de longueur.NOTE Par accord et pour un domaine donné d'application, l'essai décrit dans la présente Norme internationale peut être remplacé par le calcul de la courbe Jominy conformément à un modèle mathématique accepté (voir annexe C). En cas de litige, l'essai doit être effectué.
