43635 CAN 9A ABSTRACT OF THE DISCLOSURE Disposable test packs and methods for determining the efficacy of a sterilization cycle in steam or gas sterilizers are provided. The test packs include a container having top and bottom walls with a porous packing material, such as compressed divellicated polypropylene blown microfiber microweb, disposed within the container. The packing material challenges the penetration of the sterilant by providing a restricted pathway which acts to impede the flow of the sterilant through the test pack. A removable lid seals the upper end of the container, while a hole in the bottom wall of the container allows for the upward ingress of steam into the packing material within the container. The test pack includes either a biological indicator or a chemical indicator or both for detecting sterilant penetration and thus the efficacy of the sterilization cycle.
