Abstract
A head form for testing a variety of respirators. The head form can prevent false leak failures by having a mask registration member upon which the mask under test is mounted, the mask registration member being self lubricating. In one embodiment, the registration member is an inflatable bladder. The bladder can be configured to limit lift away of the inflatable bladder from the recess, thereby mitigating leaks in the head form assembly. The bladder may be configured to limit roll away of portions of the bladder that register against the head form, thereby reducing or eliminating leaks between the inflatable bladder and the mask under test.
