dc.description.abstract Field Change No. 985 to the MK-11 Semi-Closed Circuit mixed-gas UBA underwent manned evaluation at a depth of 650 FSW in 35 F water. FC 985 splits the hot water supply to the diver with part heating sheath-surrounded breathing bags and hoses and part being routed to a heat exchanger inside the CO2 absorbant canister. The results of 6 manned canister duration studies showed that the canister effluent CO2 was less than 1 mmHg after canister times ranging from 5 hrs 10 min to 6 hrs 2 min. This was a significant improvement over canister duration times of previous MK-11 configuration studies. A canister duration of 6 hours was assigned to the FC 985 canister. No significant differences in breathing resistance from the previous MK-11 configuration were noted. Inspired gas temperatures exceeded the minimum inspired temperature limit of 60.3 F at 650 FSW. en
