Abstract
A comparison of some of the temperature scale defining fixed points of ITS-90 was carried out between Canada (NRC), Argentina (INTI), Brazil (INMETRO) and Costa Rica (ONNUM) using a portable calibration outfit and a home-made ¼ Ω PRT.(Both developed at NRC.) The comparison was performed under practical conditions as normally exist during routine calibrations of PRTs. I.e. no special precautions were taken with the fixed points the furnaces or with the PRT
