PTB-Mitteilungen is published four times a year. It is the metrological specialist journal of the Physikalisch-Technische Bundesanstalt and mainly consists of overview articles on metrological subjects from PTB's fields of activity. Each volume focuses on a main topic. Until 2014, PTB-Mitteilungen was also the official bulletin in which the type approvals granted by PTB as well as the tests and conformity assessments carried out by PTB were published in a section of its own (named "Amtliche Bekanntmachungen"/"Official Notices"). With the new Measures and Verification Act which has been in force since 1 January 2015 and with the new Measures and Verification Ordinance, the legal basis for these notices has been omitted. From 2015 onwards, PTB-Mitteilungen is, therefore, a purely metrological specialist journal and does not publish any "Official Notices" any more.
In the table below, you will find the volumes published in the last few years. On the websites of the individual volumes, you can read a short excerpt of the articles pertaining to a special topic or you can download the complete volume as a pdf document.
