Natural gas — Calculation of thermodynamic properties — Part 1: Gas phase properties for transmission and distribution applications

ISO 20765-1:2005 refers to an international standard that outlines a method for calculating the thermodynamic properties of natural gas, specifically focusing on the gas phase properties relevant for transmission and distribution applications, like compression factor, density, enthalpy, heat capacity, Joule-Thomson coefficient, and speed of sound, within the pressure and temperature ranges typical for pipeline operations;
