Abstract: An apparatus for use in testing protective masks for leaks. The apparatus includes a test head assembly for supporting at least a portion of a protective mask to be tested for leaks. The test head assembly may be freestanding, mounted directly on a mask tester or integral with the mask tester. The test head assembly includes a body and a cover. The body includes a head section simulating at least a portion of a human head. The cover is mounted on the body to cover at least a portion of the head section. The test head assembly is preferably configured such that a portion of the cover can be inflated while the remaining portion of the cover remains in a relaxed state and in contact with the corresponding portion of the body.

Abstract: A test head assembly for supporting at least a portion of a protective mask to be tested for leaks. Preferably, the test head assembly includes a test head having a test space that is generally coextensive with an inner surface of the protective mask being tested. Although the test space is generally coextensive with the inner surface of the protective mask being tested, it is designed such that it has minimal volume to enhance the testing process by expediting test response time, reducing the time period it takes for a mask tester to reach one or more prerequisite test conditions, eliminate or greatly reduce lag time when the mask tester is operating in the probe mode and prevent dilution of challenge concentration. Preferably, the test head is formed from two or more removable sections to allow the size of the test head to be readily modified.

The test head assembly may be freestanding or it may be mounted directly on the mask tester. Preferably, the test head assembly includes a test head having a test space. The test space is operably associated with a mask tester such that a fluid from the test space is directed to the mask tester for analysis to determine if a leak exists in the mask. The test space is generally coextensive with the inner surface of the protective mask being tested.
