A method for detecting leakage of an expansion vessel,that, in an inflated form, occupies or has occupied at least a portion of a cavity,of an elastomeric article. The method includes the step of adding a tracer gas to a pressurized fluid. The method is characterized by the step of examining the atmosphere within the cavity of the elastomeric article, not within the expansion vessel, for evidence indicating that a portion of the tracer gas has escaped from the expansion vessel.
