A new wide-ranging correlation for the thermal conductivity of xenon, based on the most recent theoretical calculations and critically evaluated experimental data, is presented. The correlation is designed to be used with a high-accuracy Helmholtz equation of state, and it is valid from the triple-point temperature to 606 K and pressures up to 400 MPa. The estimated expanded uncertainty (at a coverage factor of k = 2) in the range of validity of the correlation varies depending on the temperature and pressure, from 0.2 % to 4 %. In the near-critical region, the uncertainty is expected to be larger and may exceed 4 %. The correlation behaves in a physically reasonable manner when extrapolated up to 750 K; however, care should be taken when using the correlation outside of the validated range.

基于最新的理论计算和严格评估的实验数据，提出了一种新的广泛的氙热导率相关性。该关联被设计用于高精度的亥姆霍兹状态方程，并且在三点温度到606 K以及最高压力为400 MPa的情况下有效。 在相关性的有效范围内，估计的扩展不确定性（在k = 2的覆盖因子下）取决于温度和压力，范围从0.2％到4％。在近临界区域，不确定性预计会更大，可能会超过4％。当外推到750 K时，相关性以物理上合理的方式表现；但是，在验证范围之外使用相关时应小心。
