Abstract:
An apparatus for testing a protective mask, comprising:(a) a testing unit for testing a protective mask; (b) a control system for operating the testing unit to perform at least first, second and third tests on the protective mask, said first test being one of a mask leakage test and a mask fit test, said second test being an outlet valve test and said third test being one of a drink tube valve seat test, a drink tube flow test and a drink train leakage test; (c) said control system having a first detection device for detecting a first parameter during said first test performed on the protective mask, said first parameter being challenge concentration; (d) said control system further having a second detection device for detecting a second parameter during said second test performed on the protective mask, said second parameter being fluid flow; (e) said control system further having a third detection device for detecting a third parameter during said third test performed on the protective mask, said third parameter being one of pressure and fluid flow; and, (f) said control system having at least one monitor for monitoring said first, second and third parameters to determine whether the protective mask passed said first, second and third tests.
