The MUF evaluation which confronts the observed MUF with the sigma-MUF is based on two main data sets. On the level of each single accountancy declaration, sufficient parameters must be known for stratifying the material, and on the stratum level all relevant measurement parameters must be known. Whereas the operator for his evaluation (performed as quality control), has all necessary information per item, the ESD evaluation is based on the reported accountancy declarations (normally batch declarations). This requires a different estimation technique, but the comparison between the two applications proves the validity of the ESD procedure. Additional MADES results show the possible variations in sigma-MUF when other approaches are used for material correlation and for the long-term systematic influence. Finally, some sigma-MUF estimators have been derived from the model. They can be applied in a manual way and, although not refined, are in very good agreement with the MADES calculation and are, therefore, a useful tool for the inspector in the field.
