3 This practice estimates the thermal transport properties of thermal insulation materials in-situ in field applications under pseudo steady-state conditions. It is not intended that this practice should be used as a substitute for more precise laboratory procedures such as Test Methods C177, C335, or C518.
1.4 This practice is limited by the relatively small area that can be covered by an HFT and by the transient effects of environmental conditions.
1.5 Temperature limitations shall be as speci
