Organizationally, PTB is subdivided into divisions, departments and working groups. In addition, it is subdivided into "subject areas" which cover special fields of work. The Work and Research Program of PTB encompasses the whole spectrum of
PTB, i.e. sovereign tasks and services as well as research and development.
This is in line with the way in which the tasks are dealt with at PTB. In order to use synergies, the different fields of business are closely interlinked. The subdivision into subject areas orients itself on the internationally agreed scheme which is also reflected in the structures of the Meter Convention, i.e. the Comités Consultatives of the CIPM, or in the Technical Committees of EURAMET e. V.
The four complementary specialized topics – "Metrology for Medicine", "Mathematics and Information Technology", "Physical Safety Engineering and Explosion Protection" and
"Nanometrology" – take account of additional fields of work of PTB which are not reflected in the scheme mentioned.
The subdivision into subject areas serves to place the focus on special subjects and to allocate funds correspondingly, and also to promote inter-departmental work.
In addition to the subject areas which completely image the spectrum of PTB, the Work and Research Program contains a second part which is dedicated in particular to Challenges and Future Prospects.
