Classes of Leaks. An operator must know the following types/classes of leaks in order to determine whether the
assembly is operational Learn these leakage definitions. When in doubt, notify your supervisor.
Class I
Seepage of fluid, not great enough to form drops, is indicated by wetness or
discoloration.
Class II
Leakage of fluid great enough to form drops, but not great enough to cause continuous
dripping from the item being inspected.
Class III
Leakage of fluid great enough to form drops that continuously drip from the item being
inspected.

item/system, affected with such leakage, must be checked more frequently than required in PMCS When in
doubt, notify your supervisor.
