Swatches from one ChemiCover Level B protective suit were challenged with-liquid droplets of sarin (OB) and mustard (HD) using modifications of the static diffusion procedure described in Test Operations Procedure (TOP) 8-2-501. The cumulative mass of each agent that permeated each swatch was determined over time, and the results for all swatches were used to determine a weighted-average cumulative mass for the suit. From these data, a physiologically derived breakthrough time was calculated for the suit for the purposes of comparison. In addition, intact suits were challenged with corn-oil aerosol to simulate a biological or chemical aerosol. Protection factors were determined for the suit.
