National EU Reference Laboratory for Air Pollutants Calibration Workshop 2008

The Federal Environment Agency hosts an annual calibration workshop for measurement operators of the Austrian federal states and other operators of measuring networks to ensure the traceability of calibration standards for air pollutants to the calibration standards of the Federal Environment Agency. At the calibration workshop from January to March 2008, for the ozone component, the deviations between the Federal Environment Agency’s standard and those of the participating Mes operators remained below one percent in most cases. Deviations of up to 3 % were observed for sulphur dioxide, and for nitrogen oxides and carbon monoxide up to around 1.5 %. In the course of this workshop, the flow measurement equipment and the film sets for radiometric fine dust measuring devices were compared with a film set by the Federal Environment Agency.
