Abstract
A round-robin test of X-ray residual stress determination was performed by the Groupement Français d'Analyse des Contraintes and involved 16 laboratories. The standard deviation of the measurements was about 36 MPa, but a posttreatment of the raw data with the same soft-ware reduced the dispersion to 19 MPa. Analysis of the uncertainty sources (goniometer alignment, operator, counting statistics, nonlinearity of the material, etc.) revealed that the main sources come from the data treatment and the operator.
