A pressure- and temperature-dependent equation of state (PVT EoS) parameterisation for the low-pressure face-centred-cubic polymorph of Pb metal has been derived from literature data. This PVT EoS enables the use of Pb as a pressure marker in high-pressure neutron diffraction studies on the PEARL beamline at ISIS, for example. The new equation of state supersedes the previously used version [Fortes et al., 2007: High Press. Res., 27, 201-212], being developed from a wider range of experimental data and with a more explicit description of how the final model was arrived at.
