15. What is the difference between a qualitative fit test and a quantitative fit test?A qualitative test relies on subjective detection of a test substance, whereas a quantitative fit test objectively determines the ratio of ambient testing substance to that inside the respiratorA qualitative fit test is a test with a passing result, whereas a quantitative test indicates neither pass nor failA quantitative test is only used on groups of 10 or more, whereas a qualitative test is used for smaller groups or individualsA quantitative test requires the use of vacuum chamber, whereas a qualitative test uses ambient conditions
