Determination of the physical and mechanical properties of steels using models
This document specifies the method for the verification of models for the determination of the property data of steels and the validation of the modelling process. It is applicable where modelling of mechanical or physical properties is used to substitute conventional testing for specific inspection. Models can be based on statistical data, thermo-physical data or indirect measurement (e.g. measurement of magnetic or ultrasonic data), or a combination of these methods.
This document applies only for providing the properties of rolled and/or heat-treated products such as plates, sheets, strip, sections and bars.
This document is used to demonstrate the ability of the model to supply property data which is equivalent to data, measured by conventional testing.
Any self-learning system is excluded from the scope.
NOTE A self-learning, in the spirit of an auto-adaptive model, is a model which changes its internal parameters by itself.
Ermittlung physikalischer und mechanischer Eigenschaften von Stählen mittels Anwendung von Modellen
Dieses Dokument legt das Verfahren zur Überprüfung von Modellen für die Bestimmung der Eigenschaftsdaten von Stählen und die Validierung des Modellierungsprozesses fest. Es ist anwendbar, wenn die Modellierung mechanischer oder physikalischer Eigenschaften verwendet wird, um konventionelle Prüfungen für spezifische Inspektionen zu ersetzen. Die Modelle können auf statistischen Daten, thermophysikalischen Daten oder indirekten Messungen (z. B. Messungen magnetischer oder Ultraschalldaten) oder einer Kombination dieser Verfahren basieren.
Dieses Dokument ist nur anzuwenden für die Bereitstellung der Eigenschaften von gewalzten und/oder wärmebehandelten Produkten wie Blechen, Bändern, Profilen, Stäben.
Dieses Dokument wird verwendet, um einen Nachweis zu erbringen, dass das Modell dafür geeignet ist, Eigenschaftsdaten zu liefern, welche mit den durch herkömmliche Prüfungen gemessenen Daten, äquivalent sind.
Selbstlernende Systeme sind vom Anwendungsbereich ausgeschlossen.
ANMERKUNG Ein selbstlernendes Modell ist ein Modell, welches seine internen Parameter selbst ändert.
Détermination des propriétés physiques et mécaniques des aciers à l'aide de modèles
Le présent document spécifie la méthode de vérification des modèles pour déterminer les données de propriétés des aciers et valider le processus de modélisation. Il est applicable lorsque la modélisation des propriétés physiques ou mécaniques sert à remplacer les essais conventionnels pour le contrôle spécifique. Les modèles peuvent être fondés sur des données statistiques, des données thermophysiques ou des mesures indirectes (par exemple, la mesure de données magnétiques ou ultrasonores), ou une
combinaison de ces méthodes.
Le présent document s’applique uniquement à la détermination des propriétés des produits laminés et/ou traités thermiquement tels que les tôles, les bandes, les profilés et les barres.
Le présent document permet de démontrer la capacité du modèle à fournir des données de propriétés équivalentes aux données mesurées par des essais conventionnels.
Tout système d’autoapprentissage est exclu du domaine d’application.
NOTE Un modèle d’autoapprentissage, dans l’esprit d’un modèle auto-adaptatif, est un modèle qui modifie ses
paramètres internes par lui-même.

Introduction
Since the physical and mechanical properties of steels are ultimately based upon the metallurgical
transformations during the production process, there have been numerous efforts of the manufacturers
in the past, to design models for providing property data for the whole product, in order to improve the
control of the increasingly complex processes during the manufacturing of steel products.
In doing so, the use of models not only helps to reduce the amount of testing in the scope of factory
production control, but it gives a more representative overview of the material properties of steels, since
models can use all available data, determined during the production process, whereas conventional
material testing represents in principle a spot check of the material properties at the time of sampling
and at the place where the samples were taken.
1 Scope
This document specifies the method for the verification of models for the determination of the property
data of steels and the validation of the modelling process. It is applicable where modelling of mechanical
or physical properties is used to substitute conventional testing for specific inspection. Models can be
based on statistical data, thermo-physical data or indirect measurement (e.g. measurement of magnetic
or ultrasonic data), or a combination of these methods.
This document applies only for providing the properties of rolled and/or heat-treated products such as
plates, sheets, strip, sections and bars.
This document is used to demonstrate the ability of the model to supply property data which is equivalent
to data, measured by conventional testing.
Any self-learning system is excluded from the scope.
NOTE A self-learning, in the spirit of an auto-adaptive model, is a model which changes its internal parameters
by itself.
