Electrical Quantities Department at a glance

Structure of the department

The “Electrical Quantities” department comprises the three subject fields “Direct current and low frequency”, “Magnetic measurands” and “Time and frequency”.

Accreditations and conformity assessment bodies

This subject area provides support with cases for calibration laboratories on the basis of DIN EN ISO/IEC 17025 and cooperates with technical assessors from the “Direct current and low frequency” and “Time and frequency” subject areas at the National Metrology Institute of Germany (PTB) and the private sector.

A great deal of technical and economic importance attaches for example to accreditations for the calibration of high-tech measuring instruments for the detection and process control of high-voltage discharges, but also in the area of electrical energy, for example for the testing of electricity meters and the calibration of current and voltage measuring transformers used in industry.

Benefits of accreditation

This accreditation not only certifies that calibration laboratories have a great deal of competence in the measurement of the accredited measurands, it also independently confirms maintenance of this competence by means of regular assessments.

It should also be noted that the accreditation provides evidence that the reference and working standards used are affiliated with the national standards of the PTB and that calibrations are based on internationally recognised conventions, for example on the international system of units (SI units).
