摘要：
Recommended values are given for the difference between the thermodynamic temperature T and T90, the temperature on the International Temperature Scale of 1990, for temperatures below 4.2 K. The recommendations are based on a combination of primary thermometry and thermodynamic calculations. Functions for both the difference T - T-90 and its uncertainty are provided.
