BS EN ISO 20765 - Natural gas. Calculation of thermodynamic properties

This is a multi-part document divided into the following parts:

• Part 1 Natural gas. Calculation of thermodynamic properties. Gas phase properties for transmission and distribution applications
• Part 2 Natural gas. Calculation of thermodynamic properties. Single-phase properties (gas, liquid, and dense fluid) for extended ranges of application
• Part 5 Natural gas. Calculation of thermodynamic properties. Calculation of viscosity, Joule-Thomson coefficient, and isentropic exponent
