General Information
Overview - EN 10373:2021 (Determination of the physical and mechanical properties of steels using models)
EN 10373:2021 (CEN) specifies methods for model verification and modelling process validation when using models to determine the physical and mechanical properties of steels. The standard applies where modelling replaces conventional testing for specific inspections of rolled and/or heat‑treated steel products (plates, sheets, strip, sections, bars). Models may use statistical data, thermo‑physical measurements, indirect measurement (e.g., magnetic or ultrasonic data), or combinations. Importantly, self‑learning (auto‑adaptive) systems are excluded from the scope.
Key topics and technical requirements
- Model verification: documented initial comparative testing and analysis proving the model can substitute conventional testing.
- Modelling process validation: independent validation of the process before regular use and product release.
- Application range: explicit documentation of steel grades, chemical composition, manufacturing conditions and limits for which the model is valid. Extensions that alter model parameters must be treated as a new model.
- Input data requirements: measured data must follow accepted national/international measurement standards; measurement equipment must be uniquely identified and documented.
- Output data requirements: model outputs must provide property values (e.g., proof strength, tensile strength, elongation) with specified units, accuracy and valid ranges, and be equivalent to conventional test results within manufacturer‑defined allowable deviations.
- Model monitoring and control: regular checks, comparative testing and statistical methods for ongoing monitoring; requirements for handling deviations from conventional testing.
- Quality management & documentation: requirements for responsibilities, employee qualification, measurement equipment, data handling and dispute procedures.
- Annexes: informative examples include a tensile strength calculation model, model verification illustration, and a template for predicted properties.
Applications - who uses EN 10373:2021
- Steel manufacturers and mill quality‑control teams using models for property prediction instead of full destructive testing.
- Engineers and metallurgists implementing factory production control systems and statistical process control.
- Third‑party validators and notified bodies responsible for modelling process validation.
- Buyers and specifiers who accept model‑based property declarations under inspection documents (e.g., EN 10204).
EN 10373 supports reducing testing volume while providing a more representative material characterization across production, provided models are verified, validated and monitored.

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.
