• Description:
  A new method to screen chemical protective clothing using weight and volume changes in materials after immersion was described. The method was tested using 13 materials and 75 challenge compounds. The method was designed to determine permeation and breakthrough time, the time it takes for a challenge to appear on the downstream side. The solubilities were determined by measuring changes in weight and volume after immersion of the materials in the challenge solution. Simple regression analysis using weight and volume changes was able to predict short breakthrough times. Permeation could only be predicted using weight and volume when the rate was 500 milligrams per square meter per minute. Discriminant analysis predicted breakthrough rates of more than 4 or 8 hours when actual rates were less than these only 6 percent of the time. Discriminant functions could be used with the initial thickness, weight change and final thickness after immersion to estimate breakthrough times and permeation rates. The authors conclude that these methods can be used to predict breakthrough times less than about 1 hour with 90 percent confidence. Permeation rates above 500 micrograms/square meter could also be predicted with 90 percent confidence. [Description provided by NIOSH]
