Abstract

A calibration exercise provided a preliminary investigation into the compatibility with IPTS-68for temperatures below 0°C of thermometers with low temperature coefficients. Further data, obtained for temperatures up to 300°C, support a previous hypothesis that divergence from the IPTS-68 is largely a result of stem-heat-transmission errors.
