本SAE航空航天推荐规程（ARP）描述了飞机燃气涡轮发动机气体排放的连续取样和分析。测量的气体种类包括一氧化碳（CO）、二氧化碳（CO2）、一氧化氮（NO）、二氧化氮（NO2）、碳氢化合物（HC）和水蒸气（H2O）。该ARP不包括发动机操作程序和测试模式，不用于飞行测试，也不适用于在后燃模式下运行的发动机。 人们认识到，气体分析测量技术可能会取得重大进展。本ARP的目的不是排除其他分析技术，而是形成分析飞机发动机排气所需的最低数量的传统仪器（过去十五年中常见的工业仪器）的基础。 分析员有责任证明替代测量技术的性能与本ARP中描述的技术相当（或更好）。 其他废气种类的测量超出了本ARP的范围。 应该注意的是，氧气（O2）的测量通常被认为是评估数据质量的关键，但不在本ARP的范围内。二氧化硫（SO2）通常不使用传统系统进行测量，而是根据燃料硫含量进行计算。同样，这不在本ARP范围内。

This SAE Aerospace Recommended Practice (ARP) describes the continuous sampling and analysis of gaseous emissions from aircraft gas turbine engines. The measured gas species include carbon monoxide (CO), carbon dioxide (CO2), nitric oxide (NO), nitrogen dioxide (NO2), hydrocarbons (HC), and water vapor (H2O). This ARP excludes engine operating procedures and test modes, and is not intended for in-flight testing, nor does it apply to engines operating in the afterburning mode. It is recognized that there will probably be major advances in the gas analysis measurement technology. It is not the intent of this ARP to exclude other analysis techniques, but to form the basis of the minimum amount of conventional instruments (those in common industry usage over the last fifteen years) required for the analysis of aircraft engine exhaust. It is the responsibility of the analyst to demonstrate the alternative measurement technology has comparable (or better) performance than the techniques described in this ARP. The measurement of other exhaust gas species is beyond the scope of this ARP. It should be noted the measurement of oxygen (O2) is generally accepted as essential for assessing data quality, but is not covered by this ARP. Sulfur dioxide (SO2) is normally not measured using conventional systems but is calculated from fuel sulfur content. Again this is not covered by this ARP.
