Abstract
A test fixture facilitates non-destructive testing of a protective mask. The test fixture includes a mock facial structure, a clamping form that makes a seal around at least part of the facial structure, and can employ the retaining straps of the protective mask to a make a seal around at least part of the facial structure. In use, the protective mask is tested in situ on the facial structure. In some examples, the clamping form has a negative contour of the mock facial structure or of the outer surface of a protective mask that is to be tested. The testing can include repetitive testing of the fit, structural components (e.g., ultrasonic welds and straps), and the degradation of materials as a function of donning/doffing or environmental factors (e.g., temperature and humidity).
