BS EN 14791:2017规定了标准参考方法（SRM）用于测定 从管道和烟囱排放到大气中的烟气中的二氧化硫。它是基于 采样系统和两种分析原理:离子色谱法和钍试剂法。本欧洲标准规定了要确定的性能特征和 基于测量方法的测量系统应满足的性能标准。这是适用的 定期监测和自动测量系统（AMS）的校准或控制 永久安装在烟囱上，用于监管或其他目的。本欧洲标准规定了证明替代方法等效性的标准 应用EN 14793:2017对SRM进行测试。本欧洲标准已在垃圾焚烧、联合焚烧和焚烧的现场试验中得到验证 大型燃烧装置。已在以下范围内对30分钟的采样周期进行了验证: 离子色谱法变体的SO2浓度为0.5 mg/m3至2000 mg/m3，以及SO2浓度为5 mg/m3至2000 mg/m3 根据指令2010/75/EU中规定的排放限值，钍法中的SO2。注1:2010/75/EU指令中规定的SO2排放限值范围为30 mg/m3至 800毫克/立方米。欧盟指令的排放限值以干基和干基SO2的mg/m3单位表示 273 K和101.3 kPa的标准条件。注2:装置的特性、现场试验期间的条件以及重复性值和 附录A中给出了该领域的再现性。交叉引用:prEN 13284-1:2015EN 14793:2017EN 15259:2007EN ISO 14956:2002ISO 14956:2002ISO/IEC指南98-3:2008GUM:19952010/75/EUCEN/TS 15675ISO 5725-2:1994ISO 5725-6:1994JCGM 200:2012购买本文件时可提供的所有现行修订版。

BS EN 14791:2017 specifies the standard reference method (SRM) for the determination of the sulphuric oxide SO2 in flue gases emitted to the atmosphere from ducts and stacks. It is based on a sampling system and two analytical principles: ion chromatography and the Thorin method.This European Standard specifies the performance characteristics to be determined and the performance criteria to be fulfilled by measuring systems based on the measurement method. It applies to periodic monitoring and to the calibration or control of automatic measuring systems (AMS) permanently installed on a stack, for regulatory or other purposes.This European Standard specifies criteria for demonstration of equivalence of an alternative method to the SRM by application of EN 14793:2017.This European Standard has been validated during field tests on waste incineration, co-incineration and large combustion installations. It has been validated for sampling periods of 30 min in the range of 0,5 mg/m3 to 2 000 mg/m3 of SO2 for an ion-chromatography variant and 5 mg/m3 to 2 000 mg/m3 of SO2 for the Thorin method according to emission limit values laid down in the Directive 2010/75/EU.NOTE 1 Emission limit values for SO2 laid down in the Directive 2010/75/EU are in the range of 30 mg/m3 to 800 mg/m3.The emission limit values of EU Directives are expressed in units of mg/m3 of SO2 on dry basis and at standard conditions of 273 K and 101,3 kPa.NOTE 2 The characteristics of installations, the conditions during field tests and the values of repeatability and reproducibility in the field are given in Annex A.Cross References:prEN 13284-1:2015EN 14793:2017EN 15259:2007EN ISO 14956:2002ISO 14956:2002ISO/IEC Guide 98-3:2008GUM:19952010/75/EUCEN/TS 15675ISO 5725-2:1994ISO 5725-6:1994JCGM 200:2012All current amendments available at time of purchase are included with the purchase of this document.
