Rounding of Results and Measurement Uncertainties in Calibration Certificates : Guide DKD-L 13-3

Measurement results are expressed as measured quantity value and measurement uncertainty (cf. International Vocabulary of Metrology, section 2.9) and form part of every calibration. Since representation with infinite accuracy (infinite number of places) is not possible, measurement results must inevitably be rounded. At the same time, it is necessary to adjust the number of digits of the measured value of the measurement result (result value) to the measurement uncertainty to avoid suggesting an uncertainty below...
