This document specifies the method for the verification and validation of models for the determination of the property data of steels. 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). This document applies only for verification and validation of models for providing the properties of rolled or heat treated products such as plates, sheets, strip, sections, bars, etc. This document is used to demonstrate the ability of the model to supply property data which is equivalent to data, which is measured by conventional testing. NOTE: Validation of models is part of auditing the quality management system performed by an independent body.
