measured while the mask is challenged with an aerosol, with
or without the a plugged filter canister attached.
Leakage Isolation Test Leaks normally invisible
to the naked eye are easily isolated so that repair/replacement
decisions can be made.

as part of Mask Test and isolated, for airflow leakage under
tightly controlled conditions.
Drink Tube Flow Test Tube blockage is measured
for flow.
Drink Tube Valve Leakage Test The drink tube
valve is tested for leakage under controlled pressure.
