Abstract: The expert report is based on the calibration guideline DKD-R 7-2, Edition 01/2018 [German translation of the EURAMET Calibration Guide No.18 Version 4.0 (11/2015)]. The expert report contains additional requirements regarding the practical implementation of the substitution procedure, thus supporting the high competence required of an accredited calibration laboratory. The substitution procedure is described in chapter 4.3.3 of DKD-R 7-2. By using the substitution procedure, the measurement uncertainty contribution of the load used increases with each substitution step and thus the measurement uncertainty of the weighing instrument to be stated in the calibration certificate. The substitution procedure is used to determine the indication error during calibration. The determination of repeatability and deviation due to eccentric loading is not subject of this expert report.
