The accreditation scope offers a complete listing of accredited measurands and the smallest measurement uncertainties that can be stated. The table below offers an overview of accredited measurands. The smallest measurement uncertainty that can be stated depends on the standards applied, so this listing should be interpreted as an informative list of accredited measurands rather than a definitive one. Further details along with the accredited measurands, the smallest measurement uncertainty that can be stated and the scope of validity can be found in the accreditation scope.
The term high voltage is used in two different ways in our field:
- High voltage as the measurand. Here, the form and magnitude of the electric voltage are calibrated. The objects under calibration are either the entire measuring system or just the voltage dividers for measurement of the DC voltage, AC voltage and impulse voltage. The AC power also belongs in this category.
- High voltage as a condition. The condition under which the measurement of the main measurand is to be performed. The objects under calibration are, for example, the measuring systems and the components of the capacitance measurement or impulse current measurement.
