The main advantage of qualitative fit test methods is the low cost of equipment, while their main drawback is their modest precision, and that they cannot be used to test tight-fitting respirators that are intended for use in atmospheres that exceed 10 PEL (due to the low sensitivity). To reduce the risk of choosing a respirator with poor fit ...
Fit testing (MIRE) [1] Hearing protector fit-testing is a method that measures the degree of noise reduction obtained from an individual wearing a particular hearing protection device (HPD) - for example, a noise canceling earplug or earmuff. Fit testing is necessary due to the fact that noise attenuation varies across individuals.
Qualitative fit testing with isoamyl acetate, irritant smoke, and saccharin were proposed as alternatives to quantitative fit testing in the 1980s, but doubts were raised as to its efficacy. [90] With regards to the effectiveness of fit testing in general, others have said: [90]
Fit testing of tight-fitting masks of negative-pressure respirators became widely used in US industry in 1980-s. At the beginning, it was thought that the half-mask fit quite well to the worker's face, if during a fit test the protection factor (fit factor) is not less than 10 (later, experts began to use "safety factor" = 10 during the fit ...

Acceptance testing of an aircraft catapult Six of the primary mirrors of the James Webb Space Telescope being prepared for acceptance testing. In engineering and its various subdisciplines, acceptance testing is a test conducted to determine if the requirements of a specification or contract are met.
