Abstract
Embodiments of the invention generally provide an apparatus and method for certifying a filter in a containment system without decontaminating the containment system prior to certification. The apparatus generally comprises a valve assembly selectable between at least three operational states. A first state prevents flow from prevents flow through a port of a housing. A second state fluidly couples the port to test equipment necessary to test a filter disposed within the housing. A third state seals the port but fluidly couples the test equipment to a decontamination system.
