本ARP概述了在民用和军用飞机上交付和安装之前，量化飞机推进发动机或APU上排放空气污染物标记化合物子集浓度的推荐做法。试验仅在地面试验台的稳态（非瞬态）运行期间进行。其中包括推荐的试验设置、试验程序、环境空气和排放空气取样技术，以及在给定实际限制的情况下，在量化水平上针对每种建议排放空气污染物标记化合物的一种或多种具体分析方法。

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.
