  • Quantitative Fit Testing Advantages and Disadvantage

    Qualitative fit testing is a pass/fail test to assess respirator fit based on the individual’s response to a test agent. A quantitative fit test assesses respirator fit by numerically measuring leakage into the respirator. There are advantages and disadvantages to qualitative and quantitative fit testing.

  • Standard Test Method for Nondestructive Detection of Leaks

    1.2 Leaks Detected— This test method detects package leaks by measuring the rise in pressure (vacuum loss) in an enclosed evacuated test chamber containing the test package. Vacuum loss results from leakage of test package headspace gases and/or volatilization of test package liquid contents located in or near the leak.

    In order for any fit test to be meaningful, care must be taken to ensure that if the test agent enters the respirator it is primarily through a faceseal leak. This means the respirator must be capable of filtering out substantially all of the test agent. For example, isoamyl acetate produces an organic vapor, so the respirator being tested must
