4 Leak Test
The leak test of the mask is performed with the MSA AUER Leak
Test Kit and the Leak Cap Elite after the inhalation and exhalation
valves are sealed according to the relative instructions for use.
The mask is considered tight if at a positive pressure or a nega-
tive pressure of 7.5 mbar inside the facepiece the pressure
change after one minute does not exceed 0.5 mbar.
The exhalation valve is also tested with the MSA AUER Leak Test
Kit for Full Face Masks with sealed inhalation valve, observing
the relative instructions for use. The exhalation valve meets the
requirements if with a moistened exhalation valve and a negative
pressure of 10 mbar inside the facepiece the pressure change
after one minute does not exceed 1 mbar.
