Steel. Hardenability test by end quenching (Jominy test)

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.

ZOOM ON ... the Requirements department

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:

  • mandatory clauses to satisfy,
  • non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document "ISO/IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents" as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
