scope:

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.
