Abstract

The invention concerns a method of performing an air leakage test in a low pressure chamber. The chamber is evacuated down to a predetermined low pressure level, at which level the evacuation is interrupted and the chamber closed entirely. Following a period of inactivity after attainment of the predetermined low pressure level, during which period the pressure is allowed to rise inside the chamber, the evacuation is again started. This is effected with the aid of an ejector having a higher capacity for pumping out vapour than air, and the evacuation is effected until the predetermined low pressure level is again attained.
