Qualitative tests rely on a wearer’s subjective assessment of face seal leakage. These methods, during a series of test exercises, use the wearer’s sense of smell or taste to detect face seal leakage of test agent. Qualitative tests are subject to problems with sensitivity, lack of objectiveness and inability to provide a numerical result. For these reasons Qualitative tests can only be employed for fit testing FFP’s (disposable) and half masks.

These types of RPE can be tested only (FFP’s and Half masks)
