MIL-STD-3050, DEPARTMENT OF DEFENSE DESIGN CRITERIA STANDARD: AIRCRAFT CREW BREATHING SYSTEMS USING ON-BOARD OXYGEN GENERATING SYSTEM (OBOGS) (11-MAY-2015)

MIL-STD-3050, DEPARTMENT OF DEFENSE DESIGN CRITERIA STANDARD: AIRCRAFT CREW BREATHING SYSTEMS USING ON-BOARD OXYGEN GENERATING SYSTEM (OBOGS) (11-MAY-2015)., This standard covers the design, integration, certification, and sustainment/maintenance requirements for aircraft crew breathing systems using an On-Board Oxygen Generating System (OBOGS). The intent is to provide a minimum set of criteria to ensure the safety and effectiveness of these flight critical systems. This standard shall be cited in acquisition contracts and shall be directive upon the contractor. Compliance with the standard is mandatory. This standard establishes the minimum design criteria for an aircraft crew breathing system using an On-Board Oxygen Generating System (OBOGS). The criteria address an OBOGS which produces aviator’s breathing gas by the Pressure Swing Adsorption (PSA) process. The source air for the OBOGS is assumed breathable quality air from engine bleed air or aircraft environmental control system (ECS). Integration, certification, and sustainment/maintenance are also addressed. This standard will be cited in acquisition contracts and will be directive upon the contractor. Appendices A, B, and D will be mandatory. Appendix C identifies Government testing required to verify/validate a breathing system to satisfy the requirements in Section 5. Appendix E is not mandatory.
