ASTM D3956 - 12(2018) - Standard Specification for Methane Thermophysical Property Tables

ASTM D3956 - 12(2018)

Standard Specification for Methane Thermophysical Property Tables

Status : Current   Published : April 2018



1.1 The thermophysical property tables for methane are for use in the calculation of the pressure-volume-temperature (PVT), thermodynamic, and transport properties of methane for process design and operations. Three tables are provided for gaseous and liquid methane at temperatures between 90 K and 600K at pressures to 30 MPa. Two tables provide properties for the liquid and vapor phases at liquid-vapor equilibrium (saturation properties). The third table provides properties at selected T, p points for the equilibrium phase at those conditions. The tables were developed by the National Institute of Standards and Technology from a Standard Reference Database product REFPROP, version 9.0.

1.2  This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
