Dynamic gassing out method

WebFor these reasons, the outgassing rate of critical materials has to be characterized in detail, and dynamic routine tests become therefore rather compulsory, providing the magnitude of outgassing and the temporal evolution of the outgassing rate to carry out long-term predictions. 2. TESTING METHODS Outgassing dynamic testing provides an in-depth WebOct 1, 2004 · The dynamic pressure-step method (DPM) proposed by Linek et al. (1993; 1994) is a physical method for k L a measurement that generates a concentration change in the dispersed gas by means of a small increase or decrease in the total pressure. This method seems to be independent of the oxygen concen- tration in the dispersed gas.
