SAE International (https://www.sae.org) is "The Engineering Society for Advancing Mobility – Land, Sea, Air, and Space". It maintains a set of standards related to Aircraft Bleed Air and Environmental Control Systems. Responsible for the work is the Aircraft Environmental Systems Committee (AC-9). Further standards exist, which are not part of AC-9, but which are nevertheless of interest. This Memo summarizes important statements from these SAE standards related to cabin air quality.
