42、ng 5.3.1 General Table 10 gives the dimensions of test specimens, the minimum number of measurements required to get one test result and any specific conditions which are necessary. 5.3.2 Thermal resistance and thermal conductivity Thermal resistance and thermal conductivity shall be determined in a

NOTE Thermal resistance and thermal conductivity may also be measu

Thermal resistance and thermal conductivity shall be determined directly at the measured thickness. In the event that this is not possible, they sh
