1. A method for determining a time for a challenge chemical to cumulatively permeate through a chemical protective material to a toxicity limit, the method comprising:

  • retrieving, with the processor, barrier characteristics of the chemical protective material from a computer memory;

    obtaining, with the processor, information regarding the challenge chemical, the information including a toxicity limit for the challenge chemical;

    receiving, at the processor, a temperature of the chemical protective material for which the time is to be determined; and

    using the temperature, the barrier characteristics, and the information regarding the challenge chemical, to determine a time for the cumulative permeation of the challenge chemical through the material to reach the toxicity limit at the received temperature.
