Scope
This ARP outlines recommended practices to quantify the concentrations of a subset of bleed air contaminant marker compounds on an aircraft propulsion engine or APU prior to delivery and installation on civil and military aircraft. Testing is specified during steady state (non-transient) operation only, in a ground level test bed. Included are recommended test setup, test procedures, techniques for sampling ambient air and bleed air, and one or more specific analytical methodologies for each of the suggested bleed air contaminant marker compounds at quantification levels, given practical constraints.
Rationale
This document is the required Five-Year Review and revision document. The descriptions of sampling and measurement techniques for a subset of bleed air contaminant marker compounds have been expanded and updated.

* 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.
