Abstract
A method for statistical quality assurance in an examination of steel products within a steel class is provided. Initially measurement samples are taken to determine at least one mechanical property. In addition to the measurement results, computed results of a computer-aided model for calculating the mechanical property of the respective steel product are used. Taking into account the statistical deviation between the measured results and the computed results, a statement is made as to whether the steel products have a specified probability of achieving a target value for the mechanical property.

1-8. (canceled)
A method for statistical quality assurance in an examination of steel products within a steel class, comprising:
- taking measurement samples to determine at least one mechanical property of the respective steel product;
- computing results using a computer-aided model for calculating the mechanical property of the respective steel product;
- and
- determining a statistical deviation between the measurement results and the computed results,
- wherein, taking into account the statistical deviation between the measured results and the computed results, a statement is made as to whether the steel products have a specified probability of achieving a target value for the mechanical property.
The method as claimed in claim 1,
- wherein, on the basis of a comparison of the measurement results with the computed results, a statement is made as to whether further measurement samples of individual steel products are necessary.
