Abstract
All standard platinum resistance thermometer (SPRT) subranges of the International Temperature Scale of 1990 (ITS-90) extending below 0 ◦C include the triple point of mercury as a defining fixed point. Thus, increasingly restrictive global and local regulations that aim to eventually eliminate the mining, trade and use of mercury threaten the ability of laboratories to realize the ITS-90, and work is underway to develop alternatives to mercury triple point cells for thermometer calibration.
