Natural gas - Calculation of thermodynamic properties - Part 1: Gas phase properties for transmission and distribution applications (ISO 20765-1:2005)
This part of ISO 20765 specifies a method of calculation for the volumetric and caloric properties of natural gases, natural gases containing synthetic admixture and similar mixtures, at conditions where the mixture can exist only as a gas.
The method is applicable to pipeline-quality gases within the ranges of pressure and temperature at which transmission and distribution operations normally take place. For volumetric properties (compression factor and density), the uncertainty of calculation is about ± 0,1 % (95 % confidence interval). For caloric properties (for example enthalpy, heat capacity, Joule-Thomson coefficient, speed of sound), the uncertainty of calculation is usually greater.

Gaz naturel - Calcul des propriétés thermodynamiques - Partie 1: Propriétés de la phase gazeuse pour des applications de transport et de distribution (ISO 20765-1:2005)
L'ISO 20765-1:2005 spécifie une méthode de calcul des propriétés volumétriques et calorifiques des gaz naturels, de gaz naturels contenant un adjuvant synthétique et de mélanges similaires, dans des conditions telles que le mélange ne peut exister que sous forme gazeuse.
La méthode est applicable aux gaz de qualité réseau dans les plages de pression et de température auxquelles s'effectuent normalement les opérations de transport et de distribution. Pour les propriétés volumétriques (facteur de compression et masse volumique), l'incertitude de calcul avoisine ± 0,1 % (intervalle de confiance de 95 %). En revanche, l'incertitude de calcul est généralement plus élevée pour les propriétés calorifiques (par exemple l'enthalpie, la capacité thermique, le coefficient de Joule-Thomson, la vitesse du son).
Zemeljski plin - Izračun termodinamičnih lastnosti - 1. del: Lastnosti plinaste faze za prenos in distribucijo (ISO 20765-1:2005)
Ta del standarda ISO 20765 določa metodo za izračun volumetričnih in kaloričnih lastnosti zemeljskih plinov, zemeljskih plinov, ki vsebujejo sintetične dodatke, in podobnih mešanic pri pogojih, v katerih lahko mešanica obstaja samo v plinastem stanju.
Metoda se uporablja za pline iz cevovoda v razponu tlaka in temperature, v katerem običajno potekajo dejavnosti prenosa in distribucije. Negotovost izračuna za volumetrične lastnosti (kompresijski faktor in gostota) znaša približno ±0,1 % (95-odstotni interval zaupanja). Negotovost izračuna za kalorične lastnosti (na primer entalpija, toplotna kapaciteta, Joul-Thomsonov koeficient, hitrost zvoka) je običajno večja.
