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

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
Transistors based on carbon nanostructures: what sounds like a futuristic dream could be reality in just a few years' time. An international research team working with Empa has now succeeded in producing nanotransistors from graphene ribbons that are only a few atoms wide, as reported in the current issue of the trade journal "Nature Communications."
Graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the...
