Abstract : An analysis is made to determine the factors influencing the outgassing from a specimen exposed to a vacuum. Consideration is given to the effect of the specimen temperature and prior exposure to contaminating environments. It is shown that the complete history of the specimen must be considered when estimating the outgassing rate. Two experimental programs were made to determine the constituents of the outgassing of metals. It was found that the outgassing from stainless steel was primarily H2O, H2, and N2.
