Abstract
An equation for the density of hydrogen gas has been developed that agrees with the current standard to within 0.01% from 220 K to 1000 K with pressures up to 70 MPa, to within 0.01% from 255 K to 1000 K with pressures to 120 MPa, and to within 0.1% from 200 K to 1000 K up to 200 MPa. The equation is a truncated virial-type equation based on pressure and temperature dependent terms. The density uncertainty for this equation is the same as the current standard and is estimated to be 0.04% (combined uncertainty with a coverage factor of 2) between 250 K and 450 K for all pressures, and 0.1% for lower temperatures. Comparisons are presented with experimental data and with the full equation of state.
