Gas analysis - Determination of the water dew point of natural gas - Cooled surface condensation hygrometers (ISO 6327:1981)

Describes hygrometers which determine the water content of a gas by detecting water vapour condensation occurring on a cooled surface or by checking the stability of the condensation on this surface. The hygrometers considered here may be used for determining water vapour pressure, without requiring calibration, in a system operating under total pressures greater than or equal to atmospheric pressure.

Gasanalyse - Bestimmung des Wassertaupunktes von Erdgas - Kondensations-Hygrometer mit gekühlter Oberfläche (ISO 6327:1981)

Diese Internationale Norm beschreibt Hygrometer zur Bestimmung des Wasserdampf Taupunktes von Erdgas, welche nach dem Prinzip der Wasserdampfkondensation an einer kalten Oberfläche bzw. der Messung der Stabilität des Kondensates an dieser Oberfläche arbeitet.

Analyse des gaz - Détermination du point de rosée des gaz naturels - Hygromètres à condensation à surface refroidie (ISO 6327:1981)

La présente Norme internationale décrit les hygromètres qui déterminent le point de rosée des gaz naturels en détectant l'apparition de la condensation de la vapeur d'eau sur une surface refroidie ou en contrôlant la stabilité de la condensation sur cette surface.
Le point de rosée des gaz naturels traités circulant dans les conduites de transport s'étend entre - 25 °C et + 5 °C, ce qui correspond, selon la pression du gaz, à des concentrations en eau de 50 à 200 ppm (V/V). Les hygromètres traités dans la présente Norme internationale peuvent être utilisés pour déterminer, sans étalonnage, la pression partielle de la vapeur d'eau dans un système fonctionnant sous une pression totale, supérieure ou égale à la pression atmosphérique. Il existe une relation entre la pression partielle de vapeur d'eau et le point de rosée observé, ce qui donne à cette méthode le caractère d'une mesure absolue. Lorsque le gaz contient des condensables à une température voisine de, ou supérieure à celle du point de rosée, l'observation du point de rosée est plus délicate.
