Air quality - Atmospheric measurements near ground with active Differential Optical Absorption Spectroscopy (DOAS) - Ambient air and diffuse emission measurements
This European Standard describes the operation of active DOAS measuring systems with continuous radiation source, the calibration procedures and applications in determining gaseous constituents (e.g. NO2, SO2, O3, BTX, Hg) in ambient air or in diffuse emissions.
Luftqualität - Messungen in der bodennahen Atmosphäre mit der aktiven Differentiellen Optischen Absorptionsspektroskopie (DOAS) - Immissionsmessungen und Messungen von diffusen Emissionen
Diese Europäische Norm beschreibt die Funktion von aktiven DOAS-Messsystemen mit kontinuierlicher Strahlungs¬quelle sowie deren Kalibrierung und Anwendung für die Ermittlung von gasförmigen Komponenten (z. B. NO2, SO2, O3, BTX, Hg) bei Immissionsmessungen oder in diffusen Emissionen.
Qualité de l'air - Mesurages atmosphériques à proximité du sol par Spectroscopie d'Absorption Optique Différentielle (DOAS) - Mesurages de l'air ambiant et des émissions diffuses
La présente Norme européenne décrit le fonctionnement de systèmes de mesurage DOAS active avec une source de rayonnement indépendant, et les procédures et applications d’étalonnage pour la détermination des constituants gazeux (par exemple, NO2, SO2, O3, BTX, Hg) dans l’air ambiant ou dans les émissions diffuses.
