    • For each contaminant present:
    • Were data obtained using the same sorbent material?
      • Yes - Go to "Were data obtained at similar or higher humidity?"
      • No - 5R Go to flowchart 4
    • Were data obtained at similar or higher humidity?
      • Yes - Go to "Were temperature and work rate similar?"
      • No - 5R Go to flowchart 4
    • Were temperature and work rate similar?
      • Yes - Go to "Are there multiple contaminants present?"
      • No - 5R Go to flowchart 4
    • Are there multiple contaminants present?
      • Yes - Go to "Were data obtained at similar or higher concentrations?"
      • No - Calculate the sum of all contaminant concentrations - Go to "Were data obtained at similar or higher concentrations?"
    • Were data obtained at similar or higher concentrations?
      • Yes - Go to "From breakthrough data obtain projected service life for contaminant based on concentration (total) and humidity"
      • No - 5R Go to flowchart 4
    • From breakthrough data obtain projected service life for contaminant based on concentration (total) and humidity.
    • Adjust service life for number of cartridges and work rate.
    • Multiply service life by safety factor.
    • Are there additional contaminants to process?
      • Yes - Go to "For each contaminant present"
      • No - Use the minimum service life calculated as the respirator service life - 7 Go to flowchart 4
