Safety in chemistry and materials technologies
Issue no. 4 of 18. August 2009
BAM Test Site Technical Safety will be represented (only in German).
The countdown is running…, BAM will open the gates of its Test Site Technical Safety on 09.09.2009 from 13 to 22 hours to visitors. Our visitors will be able to experience tests, hear, smell, see and much more. What can you expect on 09.09? View it for yourself.
The fastest way of reaching our test site by public transport is using lines RE3 and RE7 to the station Wünsdorf Waldstadt. Shuttle buses will commute from there between 11:30 and 22:00 hours to the BAM TTS. The last return trip takes place at 22.00 o'clock.
For our visitors, who come by car, a large parking lot will be available outside the area.

BAM has listed the world-wide commercially available nano-scale reference materials on its website as well as links to manufacturers and vendors: http://www.nano-refmat.bam.de
A data sheet in pdf format can be downloaded for each reference material. The sheets contain quantitative data on the mean value and uncertainty, information about the area of application and links to the respective manufacturer/vendor.
About 65 nano-scale reference materials of different categories (step grating, nano-objects, porosity…) are currently listed under the above link. Certified reference materials (CRMs) of the highest quality are included and these are usually offered by the national and European metrological state institutes (PTB/BAM, IRMM, NIST, AIST,…). The compilation is updated regularly.
BAM intensively supports the international standardization for nanotechnologies (for example in the German mirror committee DIN NA 062-08-17 Nanotechnologies). New requirements have been developed for calibrating the highly sensitive measurement procedures used in nanotechnologies.

Rotor blade test stand
Specialists from three of BAM’s divisions and other partners from research and industry together developed a status monitoring system for wind energy plants in the InnoNet project IMO-WIND (Integrated System of Evaluation and Monitoring for Offshore Wind Energy Plants).
The Division ‘Mechanical Behaviour of Polymers’ is responsible for monitoring the rotor blades of fibre-reinforced plastics. Loads seen in real operation have been copied for investigation purposes. The key equipment for damage behaviour investigation is a pilot-plant test stand in which the in practice 60 m long and 20 tonne rotor blades can be tested at detail at a significantly reduced scale (1:5) under laboratory conditions. The model rotor blades are equipped with an extensive net of monitoring sensors which enable the detection of naturally developing or artificially produced damage, the observation of damage extension and the assessment of fatigue strength. Rotor blades can be substantially better tested using this system and at a markedly lower cost than at the original scale.

Gold mosaics have been used as an artistic material for more than a thousand years. The skill of gold mosaic production arrived in German-speaking countries only about 1850 and was patented by the Puhl & Wagner company of Berlin at the end of the 19th century. Since they closed their business at the beginning of the 1960s, the knowledge of gold mosaic production has also vanished. Professionally manufactured gold mosaics have been provided by Italian glass manufactures ever since.
Based on historical models, the skills of gold mosaic production will be re-developed in an industrial research cooperation (Society of Industrial Research Associations − IGF, financed by the Federal Ministry of Economics and Technology).
Gold mosaics should be used not only for restoration purposes, but also for high-quality artistic and architectural shaping of interior and external space.
Gold mosaics consist of a three-layer structure. A gold film is embedded between two protecting glass plates in a sandwich-like pattern. The difficulty the process development faces is establishing a durable glass composition which is resistant to the effects of weather and ensures a proper contact between the layers.
In this project the Environmental Influences and Damage Mechanisms Working Group is responsible for the characterization of historical materials and development of modern ones. In addition, damage mechanisms are being investigated and durability tests performed and evaluated in climatic cabinets using UV irradiation and harmful gas impact. The glass manufacture participating in the project will transfer the method to be developed into commercial production.
