A research project has been completed, in which experiments involving temperature and humidity were performed on 3M experimental microfilm samples. The experiments dealt with humidity levels usual to file storage conditions and elevated temperatures to allow for accelerated aging studies. Arrhenius plots were used to extrapolate the results obtained to normal room temperatures. The data obtained indicated that the film has a life expectancy of 62 years at 30% relative humidity and 53 years at 50% when stored at 24 C.
