PTB and BAM shared exhibition space to provide information on current issues of explosion prevention and protection in Europe at the PowTech exhibition in Nuremberg from 27 to 29 March.
The manufacturers are responsible for observing the provisions of all EU Directives, which apply to any equipment being brought to market in Europe. Because this requires a clear and complete overview of the EU Directives, small and medium enterprises in particular, find this difficult to achieve.
Equipment must be explosion-protected if it is to be used in potentially explosive atmospheres. When liquids, dust and gases mixed with air are present, explosive mixtures may be produced and just a small ignition spark is sufficient to initiate an explosion of the mix.
The German industry still has problems in implementing the European Directive 94/9/EC (ATEX 100a respective ATEX 95) which came into force in 2003. Since this directive has been drafted in a general form, questions are frequently asked about its sphere of application, the requirements in special cases and the entire process of market access. Market access is only possible when the manufacturer has received or holds an EC declaration of conformity. This declaration attests that the product meets the legal minimum requirements of equipment safety. The manufacturer can then attach the CE label to the product.
These products are tested, assessed and certified by notified bodies such as PTB and BAM, who are both notified bodies within their area of competence in safety engineering.Contact: Dr. Ulrike Rockland

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
