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.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
