ASTM D3956-93(1998)

Standard Specification for Methane Thermophysical Property Tables

SCOPE
1.1 The methane thermophysical property tables are for use in the calculation of the pressure-volume-temperature (PVT), thermodynamic and transport properties of methane for process design and operations. Tables are provided for gaseous and liquid methane at temperatures between 90 and 600 K at pressures to 200 MPa. These tables were developed by the National Institute of Standards and Technology (formerly the National Bureau of Standards) upon culmination of four years of effort in acquiring available physical properties data, in performing experimental measurements, and in formulating these tables for use in thermal computations.
