Intercomparison of temperature fixed points : BCR project MTR-137
The work described in this paper concerns the manufacture and characterisation of two portable standard cells at the IMGC (Istituto di Metrologia "G. Colonnetti"). The standard cells were used for an intercomparison of different tin and zinc freezing point realisations in Europe. The cells were circulated among 12 national standards laboratories and in each one, freezing/melting experiments were carried out. After the circulation the two cells were remeasured at IMGC in order to verify that their freezing temperatures had not changed during the circulation.
