Final Report on ASTM Committee C-8 Thermal Conductivity Ceramic Fiber Round Robin

Source

A 1978 round robin analysis of guarded hot plate and calorimeter apparatuses for thermal testing of ceramic fiber insulation between temperatures of 260 and 1093°C (500 and 2000°F) is reported. A significant difference between laboratories was observed in the results, even though the results of individual laboratories were reproducible. Factors to be considered in a round robin using this material are discussed, and some of the possible sources for the differences between laboratories are reviewed. The major result of the round robin was the large range of measured thermal conductivities that different laboratories are obtaining for this material.
