National Metrology Institute of Germany

PTB (Physikalisch Technische Bundesanstalt), the National Metrology Institute of Germany, has worked in the area of Quality Infrastructure since its foundation in 1887 and is one of the leading metrology institutes in the world. With its 2,000 staff members PTB is rather a “global player” in the world of metrology and faces the responsibility involved for society, economy and science.

For nearly every physical quantity there is at PTB a working group which can measure this quantity with the highest accuracy and thus is able to further develop metrology continually. This applies to the physical base units as well as to all units derived from them. In addition to the numerous calibration services (for measurement tasks which others cannot perform with the required precision), the metrological research and development are, above all, the central points of PTB tasks.

PTB’s responsibility relates not only to the last measurable digits behind the comma and the calibration needs of the industry. PTB also promotes projects for the establishment of a Quality Infrastructure in many developing countries and in countries in transition within the scope of the German Development Cooperation. As an implementing agency of the Federal Ministry for Economic Cooperation and Development (BMZ), PTB is involved in about 40 different projects all over the world. The common objective of these projects is the strengthening of quality infrastructure, its international harmonization and mutual acceptance.
