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.
Claims15
A head form assembly for testing a respirator, comprising:
- a face portion having an outer perimeter;
- a base portion that cooperates with at least a portion of said outer perimeter of said face portion to define a recess adjacent said face portion;
- and
- a mask registration member disposed within said recess, said mask registration member being comprised of a base material and presenting a continuous registration surface for seating said respirator, said continuous registration surface being comprised of a lubricious material having greater lubricity than said base material.
A method of assembling a head form assembly for a mask fit tester, comprising:
- providing a mask registration member comprising a base material and defining a registration surface adapted to interface a respirator, said registration surface having greater lubricity relative to said base material;
- providing a face portion of a head form and a base portion of said head form, said face portion and said base portion defining a continuous interface therebetween, said mask registration member being adapted for coupling to said head form between said face portion and said base portion at said interface;
- assembling said face portion, said base portion and said mask registration member so that said mask registration member is disposed between said face portion and said base portion at said interface;
- and
- attaching said face portion to said base portion with said mask registration member between said face portion and said base portion at said interface to secure said mask registration member to said head form.
