The advances in object analysis and data processing are a real asset in science and in particular in the cultural heritage field. However, results interpretations depend on the reliability of the information obtained on the archaeological material studied. At the AGLAE facility, a specific methodology using the theory of analysis of variance (ANOVA) was followed in order to calculate the uncertainty of the PIXE and the RBS analyses due to the machine and to the data processing. Repeatability and reproducibility of measurements are studied on three PIXE standards and one RBS standard and the corresponding uncertainties are developed. Then results of RBS analyses on cultural heritage objects are presented to illustrate the discussion.
