Description

This table contains the corrections from the IPTS-27, IPTS-48, and IPTS-68 temperature scales to the ITS-90 temperature scale. These data were taken from Goldberg and Weir (1992)[1]. However, between 903.765 K and 1337.33 K, the corrections were adjusted based on the revised corrections for T₉₀ – T₆₈ determined by Rusby et al. (1994)[2] and provided in more detail in Weir and Goldberg [3]. Note: the same adjustments in this temperature range were used for IPTS-27 and IPTS-48 as for ITPS-68.
