Abstract

The new International Practical Temperature Scale of 1968 (IPTS-68) was approved by the Comité International des Poids et Mesures in 1968 and put into force by the National Physical Laboratory on January 1 this year. This revision of the IPTS-48 achieves the two objectives of making it agree with thermodynamic temperature values and of extending its range down to 13.81 K.
