德国联邦物理技术研究院（PTB）成立于1887年隶属于德国联邦经济劳工部，是世界闻名的计量和测试科研机构，但又具有政府管理职能。职工约有1600人，其中博士和研究人员有700多名。

       主要任务是进行计量学基础研究和应用技术开发（包括复现计量单位、建立和保存国家基准、进行量值传递、研究新的测试原理和方法、进行计量器具型式评价和型式批准）、代表联邦政府与国外开展计量领域的双边和多边合作。

       设有力学和声学、电学、物理化学和防爆、光学、精密工程、电离辐射、温度、医学物理和计量信息技术、科学和技术处。在柏林设有分部。

PTB performs fundamental research and development work in the field of metrology as a basis for all the tasks entrusted to it in the areas concerning the determination of fundamental and natural constants, the realization, maintenance and dissemination of the legal units of the SI, safety engineering, services and metrology for the area regulated by law and for industry, as well as technology transfer. Only fundamental research work performed by PTB itself using latest technologies will enable it to ensure on a long-term basis its metrological competence recognized on the international level, and to extend it further.

The application of modern management tools enables PTB to perform the tasks entrusted to it efficiently and thoroughly. For the long term, PTB's work program has been adapted to the requirements of its clients - trade and industry, science and society - also within the European framework. The initiation of project work guarantees flexibility when problems are to be solved on a short-term basis.

As a result of its close cooperation with universities, other research institutes and industry, PTB has become a member of the community of all those pursuing research in Germany, and it makes use of these links for the benefit of all those involved. The comparison with the national metrology institutes of other countries ensures constant critical assessment at the highest level of metrology. Together with our partners in the projects implemented within the scope of international cooperation, PTB ensures the comparability and reliability of measurement results everywhere in the world on a long-term basis.
