Abstract
In 2008/2009 an intercomparison of temperature block calibrators (TBCs) was carried out among 17 DKD accredited laboratories with Physikalisch-Technische Bundesanstalt (PTB) as the pilot laboratory. Within the framework of this intercomparison, different types of block calibrators were investigated in the temperature range between −24 °C and 600 °C. It was discovered that the devices have become significantly better during the past 10 years. As an example, the axial temperature distribution of the actual generation of TBCs is about ten times better than during the intercomparison of 1998. The results were improved in the same level and demonstrate the present capabilities of accredited laboratories in Germany.
