本文件规定了与性能试验规程结合使用的方法、仪器和计算，以定量确定固定燃烧源产生的排气气体成分。本文件涵盖的气体包括氧气、二氧化碳、一氧化碳、氮气、二氧化硫、三氧化硫、一氧化氮、二氧化氮、硫化氢和碳氢化合物。固定燃烧源包括蒸汽发生器、燃气轮机、内燃机、焚烧炉等。 包括仪器法和（通常为湿化学）法。仪器方法包括使用萃取样品进行非连续或连续取样的仪器，以及不需要取样系统的现场型仪器。

This Document specifies methods, apparatus, and calculations which are used in conjunction with Performance Test Codes to determine quantitatively, the gaseous constituents of exhausts resulting from stationary combustion sources. The gases covered by this Document are oxygen, carbon dioxide, carbon monoxide, nitrogen, sulfur dioxide, sulfur trioxide, nitric oxide, nitrogen dioxide, hydrogen sulfide, and hydrocarbons. Stationary combustion sources include steam generators, gas turbines, internal combustion engines, incinerators, etc. Included are instrumental methods as well as (normally, wet chemical) methods. The instrumental methods include instruments used for non-continuous or continuous sampling using extractive samples and in-situ type instruments that require no sampling system.
