Steels - Determination and verification of the depth of carburized and hardened cases (ISO 2639:2002)

Definition of the effective case depth, and specification of methods for determining this depth in steel.

Stahl - Bestimmung und Prüfung der Einsatzhärtungstiefe (ISO 2639:2002)

Diese Internationale Norm definiert die Einsatzhärtungstiefe und legt Verfahren zur Bestimmung dieser Tiefe bei Stahl fest.
Sie gilt für
a)   die Einsatzhärtung durch Aufkohlen und Karbonitrieren;
b)   Teile, die nach der endgültigen Wärmebehandlung, in einem Abstand von der Oberfläche, der dem Dreifachen der Einsatzhärtungstiefe entspricht, eine Härte von weniger als 450 HV 1 aufweisen.
Sind diese Bedingungen nicht erfüllt, wird die Einsatzhärtungstiefe durch besondere Vereinbarung festgelegt.
Bei Stählen, bei denen das Werkstück in einem Abstand von der Oberfläche gleich der dreifachen Einsatzhärtungstiefe eine Härte aufweist, die größer als 450 HV 1 ist, kann dieses Bewertungsmerkmal ebenfalls angewendet
werden, sofern ein Härtegrenzwert für die Einsatzhärtungstiefe gewählt wird, der - jeweils in Stufen von 25 Einheiten - größer als 550 HV 1 ist.

Acier - Détermination et vérification de la profondeur de cémentation (ISO 2639:2002)

L'ISO 2639:2002 définit la profondeur de cémentation, et spécifie des méthodes de détermination et de vérification de cette profondeur, dans l'acier.
Elle est applicable
1. aux couches cémentées et aux couches carbonitrurées;
2. aux pièces qui ont à l'état du traitement d'utilisation une dureté inférieure à 450 HV 1 à une distance de trois fois la profondeur de cémentation de la surface.
La profondeur de cémentation est définie par convention particulière lorsque ces conditions ne sont pas satisfaites.

ISO 2639:2002(E) © ISO 2002 – All rights reserved iii 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. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 2639 was prepared by Technical Committee ISO/TC 17, St
