| Abstract: | Thermal transmittance testing is an important way of evaluating thermal performance of thermal barrier profiles. The test method of thermal barrier profiles of aluminium alloy was presented, the uncertainty sources in thermal transmittance testing were analyzed, and the measuring uncertainty for thermal transmittance of thermal barrier profiles was evaluated, and the matters needing attention provides were provided. The result showed that probability of occurrence of measurement results of thermal trarrnittance was 95% in（2. 90±%0. 06） W . m2.K-1. |
