Abstract
A review is presented of the existing measurements of the triple-point temperatures Ttp of deuterium. All data are adjusted to a common temperature scale, and error limits are proposed where none was provided in the source publications. The effects of sample contamination are also considered. Impurity corrections, based on estimates from vapor-pressure measurements, are applied to the results. The analytical representation Ttp(x)=18.680+0.155x, where x is the fraction of p-D2 (J=1), is found to represent Ttp to ±0.010 K. The value, 18.723±0.010 K, measured most recently on normal deuterium is consistent with the most accurate and precise of the earlier data.Keywords
