ASTM Test for Thermal Conductance and Transmittance of Built-Up Sections by Means of the Guarded Hot Box (C 236) states that the net heat flow through the metering box walls should be minimized. In order to satisfy this requirement, a testing procedure was developed to experimentally define the required thermopile emf set point across the metering box walls of the W.R. Grace and Company guarded hot box (GHB). This method of calibration can be applied to any GHB. Thermal conductances of three specimens were measured using the results of the calibration procedure and were found to be within 3% of the values obtained by other independent test methods.
