NF EN 1622

Water quality - Determination of the threshold odour number (TON) and threshold flavour number (TFN)

Le présent document prescrit des méthodes quantitatives de détermination du TON et du TFN des eaux, de même qu'une méthode qualitative de détermination de toute odeur et/ou flaveur anormales. Deux méthodes quantitatives sont décrites : une méthode courte, applicable soit si l'échantillon n'a pas d'odeur ni de flaveur, soit si l'odeur et la flaveur doivent être comparées à un seuil spécifié et une méthode complète, applicable lorsque le seuil pour l'échantillon doit être déterminé.
