Calibration and performance testsThe experts of our Environmental monitoring body have been working in the field of calibrating instruments for continuous emission measurement for many years. Plants in accordance with the 13th and 17th Federal Ambient Pollution Protection Regulation (BImSchV) and the Technical Instructions on Air Pollution Control (TA Luft) have to undergo calibrations and performance checks regularly. Calibration consists of determining the functional relation between the values measured by the automatic measuring instrument and an independent reference measuring method. Each calibration includes a prior performance test of the measuring instrument. |
The entering into force of DIN EN 14181 entailed profound changes for calibration activities. Cement plants according to the 17th BImSchV are subject to the new standard since December 2005 already. At the end of 2006 the German guideline VDI 3950, which is applicable for plants according to TA Luft, was adapted correspondingly. Calibrations and performance tests of continuous measurement devices at plants according to TA Luft now have to fulfil the same requirements as plants according to the 17. BImSchV. As a consequence, the continuous control of measuring instruments to be carried out by plant operators has to meet higher demands now. We shall be pleased to inform you of the most important changes personally.
We possess ample experience in the calibration of instruments for continuous mercury measurement. In the cement industry in particular, the use of these instruments frequently involves difficulties. In order to be able to scrutinise the complex questions in depth, we have also engaged in research activities to deal with the topic of continuous mercury measurement technique.
