News

The International System of Units (SI) is being fundamentally reformed. In the fall of 2018, a large international conference is going to set the historical course for the future of the SI. The new SI will be based on fundamental constants instead of the seven base units as previously. PTB has accompanied this process by means of various large-scale research projects – among others the Avogadro project for the redefinition of the kilogram and of the mole, and the Boltzmann project for the redefinition of the kelvin. Moreover, PTB has played an important role by providing information on these reforms. PTB has recently published an info sheet about the new SI (in German and in English); you are welcome to order one free of charge from the Press and Information Office or to download it from our website.

Evaluations

Evaluation report (in Geman only)
Stand: Januar 2012

In 2002, PTB as a whole was evaluated – with an excellent outcome. In 2008, an evaluation of PTB research followed, carried out by the Wissenschaftsrat (German Council of Science and Humanities) with a subsequent Implementation Report in 2012. You will find more about this at Opens internal link in current windowPTB in the World of Research or in the pdfs of the evaluation reports which you can download in the right-hand column.

The next evaluation will follow in 2016.
