44、it is recommended that the specificationdata be presented as conductivity versus temperature, severalexisting specifications may contain mean temperature datafrom tests conducted at specific hot and cold surface tempera-tures. In these cases, the conductivity as a function of tempera-ture from the C
45、 1045 analysis may provide different results. Toinsure that the data is compatible, a C 680 analysis, using theconductivity versus temperature relationship from C 1045 andthe specific hot and cold surface temperatures, is required todetermine the effective thermal conductivity for comparison tothe s
