fit test

The use of a procedure to qualitatively or quantitatively evaluate the fit of a respirator on an individual. A qualitative fit test (QLFT) is a pass/fail test to assess the adequacy of respirator fit that relies on the individual’s response to the test agent. A quantitative fit test (QNFT) is an assessment of the adequacy of respirator fit by numerically measuring the amount of leakage into the respirator.
