[中文适用范围]： 本文件规定了固定源烟气中二氧化硫 (SO2) 的测定方法，并描述了自动测量系统的基本结构和关键性能特征。该方法允许使用永久安装的测量系统对 SO2 排放量进行连续监测。本文件描述了与一系列分析仪相关的提取系统和原位（非提取）系统，这些分析仪使用以下原理运行： — 非色散红外吸收 (NDIR)； — 傅里叶变换红外 (FTIR) 光谱； — 激光光谱技术或可调谐激光光谱 (TLS)； — 非色散紫外吸收 (NDUV)； — 差分光学吸收光谱 (DOAS)。其他等效仪器方法只要满足本文件中规定的最低性能要求即可使用。可以根据本文件或类似方法使用参考材料验证测量系统。基于上述原理的自动测量系统 (AMS) 已在本应用中成功用于附录 E 中所示的测量范围。 [外文原描述]： This document specifies a method for the determination of sulfur dioxide (SO 2 ) in flue gases of stationary sources and describes the fundamental structure and the key performance characteristics of automated measuring systems. The method allows continuous monitoring with permanently installed measuring systems of SO 2 emissions. This document describes extractive systems and in situ (non-extractive) systems in connection with a range of analysers that operate using, for example, the following principles: — non-dispersive infrared absorption (NDIR); — Fourier transform infrared (FTIR) spectroscopy; — laser spectroscopic technique or tunable laser spectroscopy (TLS); — non-dispersive ultraviolet absorption (NDUV); — differential optical absorption spectroscopy (DOAS). Other equivalent instrumental methods can be used provided they meet the minimum performance requirements specified in this document. The measuring system can be validated with reference materials, according to this document, or comparable methods. Automated measuring system (AMS) based on the principles listed above has been used successfully in this application for the measuring ranges as shown in Annex E.
