PTB is a very "colorful" institution. The reason for this is its "multiple role": looking at the amount of its research and development work, its main focus is as a research institute. Yet its many legally regulated duties and not least its important role for industry, mean it is one of the so-called departmental research institutes of the Bundesministerium für Wirtschaft und Energie (Federal Ministry for Economic Affairs and Energy). This complexity and not least its history which stretches back over more than 125 years are the reason for the large number of very different portrayals of PTB. Here you will find the free brochures published by the Press and Information Office, arranged in line with PTB's structure or according to important subjects.
