Comparative analysis of the chosen properties of filtrating type protective masks

Abstract

The results of comparative experimental testing of different filtrating type masks are presented in this study. Some of the most important functional properties have been tested on available models of Italian, French, British, Canadian, Swiss, American, and three models of Serbian military protective masks (M3 of the latest generation, as well as M2, and M2FV models of the previous generation). Using of the standardized testing methods, mask models have been tested on protection factor, dynamic resistance of the exhaust valve and its static permeability, the overall inhalation resistance of protective masks, field of view and optical properties. Based on experimental results obtained, it can be concluded that the Serbian mask M3 is on approximately same quality level as tested foreign masks, and above Serbian protective masks of the previous generation marked M2F and M2FV.
