This standard provides contaminant limits for aircraft engine and APU bleed air compounds that are surrogates for the range of compounds that may be present in bleed air. The surrogate compound limits will provide users of the standard a measure for determining suitability of bleed air purity for aircraft occupant safety, health and comfort. This document provides guidance for assessing multiple contaminants when present together in bleed air. The contaminant limits in this standard are applicable for engine qualification process on engine test beds and flying test bed aircraft, and for criteria to assess bleed air purity of operational aircraft.
