Steel - Hardenability test by end quenching (Jominy test) (ISO 642:1999)

Method for determining the hardenability of steel by the end quench, (Jominy test), by using a test piece of 25 mm diameter and 100 mm long.

Stähle - Stirnabschreckversuch (Jominy-Versuch) (ISO 642:1999)

Diese Internationale Norm legt das Verfahren zur Ermittlung der Härtbarkeit von Stahl durch den Stirnabschreckversuch (Jominy-Versuch) an einer Probe mit 25 mm Durchmesser und 100 mm Länge fest. Anmerkung: Der in dieser Internationalen Norm beschriebene Versuch kann nach Vereinbarung und für einen bestimmten Anwendungsbereich durch die Berechnung der Jominy-Kurve nach einem anerkanntenmathematischen Verfahren (siehe Anhang C) ersetzt werden. In Schiedsfällen muß der Versuch durchgeführt werden.

Acier - Essai de trempabilité par trempe en bout (essai Jominy) (ISO 642:1999)

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.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
