1. The institution responsible for measurement standards and scientific metrology in Germany is Physikalisch-Technische Bundesanstalt (PTB).

It is the National Metrology Institute providing scientific and technical services.

PTB’s responsibilities are to achieve progress and ensure reliability in the field of metrology for the benefit of society, economy and science with research, measurement and consulting being its main activities.

Areas of PTB’s work are:

·           realisation, reproduction and dissemination of the SI units;

·           development of national measurement standards;

·           determination of fundamental constants and exploitation of quantum effects for realising the units;

·           provision of traceable reference materials and determination of material properties;

·           development of accurate and reliable measurement procedures;

·           contribution to standardization and technology transfer by consulting and seminars;

·           pattern evaluations, approval and consulting;

·           metrology in commercial transactions, environmental, labour and radiation protection, medicine and safety engineering;

·           cooperation in European and international metrology organisations as well as with other metrology institutes;

·           technical cooperation with developing and newly industrialised countries.

2. Institutions responsible for legal metrology

The basic principles of legal metrology are stipulated by the Units Act and the Verification Act, including the relevant implementing ordinances and additional regulations.

The physical and technical basis of the units to be applied in official and commercial transactions is today’s International System of Units (SI).

The tasks of legal metrology are distributed between the federal and the state authorities. PTB is responsible for type examination and type approval of measuring instruments and traceability to national standards used by the verification authorities.

The verification authorities of the sixteen states and the officially approved test centres for measuring instruments in the field of electricity, gas, water and heat are responsible for the individual testing of measuring instruments subject to mandatory verification.

3. Institutions responsible for calibration service

Calibrations are performed by the calibration laboratories accredited by the “Deutsche Akkreditierungsstelle GmbH (DAkkS)” founded by the German Government in Cooperation with the German Federation of Industry (BDI) The basis of the DAkkS (former DKD) accredited calibration laboratories is the traceability of their reference standards to the national standards provided by the National Metrology Institute, the PTB or other National Metrology Institutes. Industrial laboratories and other institutes which, due to their trained personnel and equipment, are able to perform measurements with the required uncertainty and whose standards are traceable to the national standards of the PTB, are accredited as calibration laboratories.

Accreditation is granted by DAkkS after assessment of the laboratories in accordance with the standard DIN EN ISO/IEC 17025. Membership of DAkkS in the European Cooperation for Accreditation (EA) and the International Laboratory Accreditation Cooperation (ILAC) ensures the recognition of the calibration certificates in all member countries worldwide. At present there are about 440 accredited calibration laboratories for electrical, magnetic, dimensional, mechanical, acoustical, fluid and optical quantities, as well as for chemical analysis, reference materials, time and frequency, ionising radiation and radioactivity, temperature and humidity.
