Within the International Temperature Scale of 1990 (ITS-90) the platinum resistance thermometer (PRT) is used to realize the scale from approximately 13,8 K to 1 235 K. Such a temperature range is wider than the corresponding range in the Internation

The triple points of krypton, argon, nitrogen and neon have been realized with reproducibilities of ±0.2 mK, ±0.1 mK, ±0.1 mK, and ±0.2 mK respectively. The results suggest that the triple points of argon and nitrogen make excellent reference tem

The use of an additional defining point on the International Temperature Scale between 90.188 K and 273.15 K is advocated. The triple point of xenon is suggested as the candidate and an experimental technique which gives the required degree of reprod

Townsend primary and secondary ionization coefficients have been measured and sparking voltages deduced for di- and tri-methyl ethylene and for isoprene over a pressure range of 2 to 200 Torr and a parallel plate gap distance up to 1 cm yielding deri

The β-γ transition in oxygen has been realized with a reproducibility of ±0.2 mK. The cryostat and techniques used to produce sharp and reproducible transitions are described. The results suggest that the β-γ transition may be used to provide a

The effect of replacing the boiling point of water with the triple point of gallium in several interpolation schemes for platinum resistance thermometers below 273.15 K is investigated. The sensitivity of the schemes to calibration errors in the gall

The use of the triple points of deuterium and xenon is investigated in some interpolation schemes for platinum resistance thermometers between 13.8 K and 273 K. The use of these triple points together is shown to lead to a large sensitivity to errors

The boiling point and triple point of pure oxygen have been realized with a reproducibility of ±0.2 and ±0.1 mK respectively. These realizations have been used to determine the temperatures of the boiling point of argon as 87.2941 K and the triple
