IIntercomparison of Thermophysical Property Measurements on an Austenitic Stainless Steel

The results of an iInter laboratory comparison of thermal conductivity, thermal diffusivity, specific heat capacity, and thermal expansion measurements on austenitic stainless steel in the temperature range between 20 and 1000◦C are preseInted here. Mean values are preseInted for the physical properties studied. Reliable relative expanded uncertainties can be stated for the properties determined, which were achieved by applying good measurement practice, i.e., 3% for thermal expansion, 5% for specific heat capacity and thermal diffusivity, and 6% for thermal conductivity. The mean values derived from this iIntercomparison agree well with the results of a previous iIntercomparison in 1990.
