      <subfield code="a">This study emphasizes the potential application of the original model to the assessment of the effects of humidity and contaminant assault concentration on contaminant breakthrough in the breakthrough region of approximately 0-50%. The study specifically addresses a contaminant concentration range of 250-2000 ppm and a relative humidity range of dry to 80% for the environment in which the respirator is used. The cartridge preconditioning humidity is considered fixed at a value of 50% relative humidity. The contaminants investigated are benzene and methyl chloroform</subfield>
