Development of Test Methods for Single Use Organic Vapor Respirators.
The Bendix Corporation, Cocoa Beach, Florida, 1978 Jul:60 pages
The development of a certification testing program for single use valveless, organic vapor respirators is reviewed. The variability of respirator performance, parameter, constant flow, and analytical method tests are described, along with the respirators that were tested. Breathing machine test and steady state flow apparatus specifications, and test procedures are described. Results of variability and steady flow tests, effects of test parameters, and equilibrium data are summarized, along with recommended test parameters for the further study of a certification method. The authors conclude that except for maintaining a moist exhalation atmosphere of 95 percent relative humidity, the physiology of a breathing human was not totally considered. Although no mathematical relationships were found to accurately predict the initial breakthrough times of valveless organic vapor respirators, the authors recommend that a usable certification method can be based on the equilibrium phenomenon of this respirator.
