Abstract:

The MK 24 full face mask FFM is configured to support MK 16 MOD 0 UBA decompression dives and SEAL delivery vehicle SDV transits. During certification testing at depths shallower than 15.3 msw fsw the FFM produced chatter upon inhalation in the open circuit mode, apparently due to newly-designed second stage regulator poppet valves and demand levers.
