EN ISO 20765-2:2018

Natural gas - Calculation of thermodynamic properties - Part 2: Single-phase properties (gas, liquid, and dense fluid) for extended ranges of application (ISO 20765-2:2015)

ISO 20765-2:2015 specifies a method to calculate volumetric and caloric properties of natural gases, manufactured fuel gases, and similar mixtures, at conditions where the mixture may be in either the homogeneous (single-phase) gas state, the homogeneous liquid state, or the homogeneous supercritical (dense-fluid) state.

Erdgas - Berechnung thermodynamischer Eigenschaften - Teil 2: Einphaseneigenschaften (gasförmig, flüssig und dicht-flüssig) für den erweiterten Anwendungsbereich (ISO 20765-2:2015)

Gaz naturel - Calcul des propriétés thermodynamiques -- Partie 2: Propriétés des phases uniques (gaz, liquide, fluide dense) pour une gamme étendue d'applications (ISO 20765-2:2015)

L'ISO 20765-2:2015 spécifie une méthode de calcul des propriétés volumétriques et calorifiques des gaz naturels, des gaz naturels manufacturés, et des mélanges similaires, dans des conditions telles que le mélange peut exister à l'état gazeux homogène (phase unique), à l'état liquide homogène, ou à l'état supercritique homogène (fluide dense).

Zemeljski plin - Izračun termodinamičnih lastnosti - 2. del: Lastnosti enofaznih sistemov (plin, tekočina in gosta tekočina) za razširjen obseg uporabe (ISO 20765-2:2015)

Standard ISO 20765-2:2015 določa metodo za izračun volumetričnih in kaloričnih lastnosti zemeljskih plinov, gorivnih plinov in podobnih mešanic pri pogojih, v katerih je mešanica lahko v homogenem (enofaznem) plinastem stanju, homogenem tekočem stanju ali homogenem superkritičnem (gosto tekočem) stanju.
