PART 1: ABSTRACT
The results of some case exchange experiments is reported. The case used for these experiments had a volume of 1.5 m3 and composed of 4mm polycarbonate sheets with pre-drilled holes covered with duck tape, (See slides from presentation).
N2O, Temperature and relative humidity were measured at various points inside and outside the case. The N2O was squirted into the case (maximum total concentration was 5%) and the concentrations of N2O, RH and temperature measured with time. This set-up was chosen as it gives the basis of a simple and economic method for the measurement and interpretation of case exchange rates in working (i.e. with artefacts) museum cases.
Data from the laboratory case was presented and showed a number of characteristics:
