Abstract

This paper reviews the main sources of uncertainty in laboratory measurement of thermal resistance with a heat flow meter apparatus over a wide range of testing conditions. It deals with calibration uncertainties in general terms, indicates techniques for controlling instrument precision, analyses the sensitivity of results to some changes in testing conditions, and describes two procedures for establishing transfer standards that permit comparison of absolute and relative measurements.
