Natural gas — Calculation of thermodynamic properties — Part 4: Gross characterisation method for fluid phase properties

General information

20.00     Jan 8, 2026

ISO

ISO/TC 193/SC 1

International Standard

Scope

The method calculates volumetric and caloric properties of natural gases, manufactured fuel gases, and similar mixtures, at conditions where the mixture is in the homogeneous (single-phase) fluid state. Properties such as hydrocarbon dew point are unlikely to be calculated accurately.
