Intercomparison of zinc freezing point cells and standard platinum resistance thermometers

Technical Report ·
OSTI ID:5214715

Four standard platinum resistance thermometers (SPRTs) and four zinc freezing-point cells are intercompared. Pronounced differences are found between the SPRTs but no differences are found between the cells. Analysis of data indicates interaction between cells and SPRTs in two instances. One interaction is found to be spurious because of an anomalous data point. No grounds are found for discounting the validity of the second interaction. Reasons are given for repeating this work after refinements in procedure and equipment are made.
