		About PTB PTB - the national metrology institute providing scientific and technical services. What are PTB’s capabilities? PTB measures with the highest accuracy and reliability - metrology as the core competence. For whom does PTB work? PTB stands for progress and reliability in metrology for the benefit of society, trade and industry, and science. At the Physikalisch-Technische Bundesanstalt (PTB), not only time is made - we also realise the metre, the kilogram, the newton, the volt... PTB is Germany’s national metrology institute and thus the highest authority for all aspects of correct and reliable measurement. The tasks have been laid down in 27 laws, ordinances and guidelines. They include the realisation, maintenance and dissemination of legal units, the setting-up and development of a uniform, internationally applicable system of units (Système international d’unités (SI)) in cooperation with the other national metrology institutes, and sovereign tasks in the fields of health, safety engineering, consumer protection, industrial safety, radiation protection and environmental protection. As the metrological competence centre PTB is the firsthand contact for customers from science, economy and society. The interests of these different groups of customers are also reflected in the four areas of work of PTB "Fundamentals of Metrology" (Objectives: realisation and dissemination of the SI units) "Metrology for economy" (Objectives: increasing the efficiency of economy, safeguarding of employment) "Metrology for society" (Objectives: promotion of consumer protection, safeguarding of living conditions) "International affairs" (Objectives: removal of technical barriers to trade, unification of metrology)				Measure what is measurable, and make measurable what is not (yet) so         Physikalisch-Technische Bundesanstalt (PTB) Site Braunschweig Bundesallee 100 D-38116 Braunschweig Tel.: +49 531 592-0 Fax: +49 531 592-92 92 Site Berlin Abbestraße 2-12 D-10587 Berlin Tel.: +49 30 34 81-1 Fax: +49 30 3481-490 E-mail: info@ptb.de
