Scope:

Aircraft propulsion engine and APU manufacturers shall demonstrate that air provided to the aircraft cabin is of acceptable quality. This ARP provides the basic information required to perform an engine bleed air quality certification test. This document provides the recommended levels and describes the measurement procedures required for the quantification of gaseous and particulate contaminants, which may be present in aircraft engine bleed air.

Rationale:

This document is the required 5 year review and revision document. Since the original draft was introduced in 1995 significant changes have transpired in the formation of aircraft cabin air quality specifications and standards. This document reflects the most current standard recommendations for aircraft cabin air quality which have been drafted by ASD-STAN for use within the European States, but also incorporates information from NIOSH recommendation. Acceptable engine generated contaminant limits are inherently lower than allowable cabin contaminant levels, to ensure that contaminant levels are maintained below maximum allowable levels during aircraft operation.
