Abstract
A Complex test method for evaluating protective apparel in aerosol hazard conditions has been developed and examined under laboratory conditions. The effectiveness of the harder or “collection efficiency” of aerosol protective apparel (APA) depends upon its structural properties such as porosity, thickness, and permeability as well as on its hydrodynamic properties, i.e., pressure drop. Aerosol generating systems and methods of measuring penetration and evaluating data are described. A method of testing protective apparel materials using a standard asbestos aerosol then is described and discussed in detail.
