Résumé
It is well known that interlaboratory tests are a powerful tool to improve the quality of measurements. However they are difficult and costly to organise in the framework of emission measurements because of several reasons (too small measuring platforms, access to industrial plants...). In order to facilitate these tests, French authorities asked INERIS to built a testing bench, which could simulate industrial gaseous emissions of easily modified composition. The bench was originally designed mainly for having a constant concentration of gaseous pollutants (SO2, NOX, HC1, VOC). Work is in progress for semi-volatile pollutants injection.
