Manned submersibles. Breathing air supply and CO2 adsorption systems. Performance requirements and recommendations Ingestion-build-223009 Why should you use PD1 Scope This document specifies performance requirements and gives recommendations for the design of breathing air supply and CO2 absorption systems of manned submersibles, capable of maintaining suitable life support conditions in the manned compartments. It is applicable to manned submersibles where the internal pressure of the manned compartment is normally maintained at or near to one atmosphere. It is not applicable to submersibles where the
