ABSTRACT:
A method for testing hydrostatic pressure of an inflator housing constituting an outer shell container for various inflators, which can evaluate a hydrostatic pressure conveniently is provided. The method comprises the steps of injecting water from a small hole provided in the inflator housing until the pressure inside the inflator housing reaches a predetermined pressure of an evaluation standard, keeping the inflator housing sealed tightly, or comprises the step of increasing the pressure inside the inflator housing to the predetermined pressure while injecting water in the inflator housing, draining the injected water, and drying the interior of the inflator housing.
