The method is for making quantative determinations of the leak rates of pressure vessels charged with dry permanent gases. The pressure vessel charged with a dry permanent gas is enclosed within a sealed chamber having a small clearance between it and the vessel. The clearance volume is evacuated. A predetermined quantity of the gas is introduced into the clearance volume to produce a pressure rise which corresponds to the maximum allowable leak rate of the vessel. A McLeod guage is used to measure the pressure changes in readings are noted.
