| Summary: | The accuracy of thermal conductivity measurements is even more requested for materials
characterization in energy-efficient buildings field. ENEA-UTTMATF and CertiMaC research
group, as national institute and private laboratory respectively, cooperate in development
of new measurement and analysis methods applied to buildings materials and their
performances. For what concerns this kind of measurements, an Heat Flow-meter Transducer
(HFT) is used. In order to give to both customers and other research institutes involved
in the same field (e.g. International Comparison or International Round Robin Tests) the
most exhaustive evaluation of the tested material thermal conductivity, a complete
uncertainty analysis is implemented on the HFT measures. This uncertainty analysis,
developed accordingly to the international standards and with the contribution of INRiM
Institute, is described in this paper. |
