This paper examines the accuracy of various theoretical methods for the analysis of experimental data on interzone air movement obtained using a single tracer gas technique. Two types of data were examined; (a) well conditioned data obtained in the laboratory from measurements of air movement between two chambers and (b) less well conditioned measurements made in houses. Errors in calculated flow rates were found to be in the range -8 to 33% for well-conditioned measurements. For less well-conditioned data the estimated values of air flow rates were spread over a wide range and it was not possible to establish the errors in these values as the real flow rates were unknown.
