本文件规定了手动测量方法，包括取样和不同的分析方法 工业废气中氨（NH3）质量浓度的测定方法 工业植物，例如燃烧植物或农业植物。所有的化合物 在取样温度下挥发，在取样过程中离解时产生铵离子 用这种方法测量吸收溶液中的氨含量，从而得出溶液中的挥发性氨含量 废气。 本文件规定了一种独立的测量方法，该方法已在现场得到验证 在标准条件下，在约8 mg/m3至65 mg/m3的NH3浓度范围内进行试验。验证范围的下限是在试验装置的运行条件下确定的。测量方法可在较低值下使用，具体取决于所用分析方法的采样持续时间、采样量和检测限。 注1:工厂、现场试验期间的条件和现场获得的性能特征 附件A中给出了这些信息。 这种测量方法也可用于氨排放的间歇性监测 至于永久安装的自动氨测量系统的校准和验证。 注2:在EN 14181中，一种独立的测量方法称为标准参考法（SRM）。交叉引用:ISO 14911ISO 11732ISO 7150-1ISO/IEC指南98-3:2008版1ISO 17179EN 15259ISO 9096ISO 20988ISO 14956EN 14181购买本文件时提供的所有当前修订版均包含在购买本文件中。

This document specifies a manual method of measurement including sampling and different analytical methods for the determination of the mass concentration of ammonia (NH3) in the waste gas of industrial plants, for example combustion plants or agricultural plants. All compounds which are volatile at the sampling temperature and produce ammonium ions upon dissociation during sampling in the absorption solution are measured by this method, which gives the volatile ammonia content of the waste gas. This document specifies an independent method of measurement, which has been validated in field tests in a NH3concentration range of approximately 8 mg/m3to 65 mg/m3at standard conditions. The lower limit of the validation range was determined under operational conditions of a test plant. The measurement method can be used at lower values depending, for example, on the sampling duration, sampling volume and the limit of detection of the analytical method used. NOTE 1 The plant, the conditions during field tests and the performance characteristics obtained in the field are given in Annex A. This method of measurement can be used for intermittent monitoring of ammonia emissions as well as for the calibration and validation of permanently installed automated ammonia measuring systems. NOTE 2 An independent method of measurement is called standard reference method (SRM) in EN 14181.Cross References:ISO 14911ISO 11732ISO 7150-1ISO/IEC GUIDE 98-3:2008 Ed 1ISO 17179EN 15259ISO 9096ISO 20988ISO 14956EN 14181All current amendments available at time of purchase are included with the purchase of this document.
