Abstract
This report describes intercomparison results obtained in the framework of the EC Directive 779/80 EEC fixing limit and guide values for SO{sub 2}, Black Smoke (BS) and Total Suspended Particulates (TSP). In two quality assurance programmes, the calibrations and measurement procedures used in the Member States were compared to the procedures of the reference methods laid down in the Directive. Orientated towards laboratory intercomparisons, the first quality assurance programme (1985-86) aimed at testing the readings of the instruments using reference materials: air SO{sub 2} mixtures at low SO{sub 2} concentration, BS and TSP filters at different darkness level and load. These materials were circulated among 40 laboratories and 4 measuring stations. For SO{sub 2}, on the average, 90% of laboratories and 50% of network stations, provided results comparable with the SO{sub 2} reference method (tetrachloro-mercurate pararosaniline, TCM method). Where the deviations exceeded + 10%, this was because of inappropriate handling of the calibration. For BS, largest deviations were caused by differences in configurations of filter/reflectometer and of the conversion curves. For TSP, a conditioning procedure showed the necessary for a careful testing if the method of the Directive is not used. The reference materials for SO{sub 2} and BS were
