Abstract :
Comparison measurements were performed on mercury triple point cells using two maintenance baths and freezing and melting methods. The purpose is to reassess the uncertainty of realized temperature for an additional maintenance bath and melting method. By this reassessment, no significant change is required for the temperature realization uncertainty of 0.33 mK with the coverage factor k = 1.
