本文件规定了基于自动方法的标准参考方法（SRM），用于测定排放到大气中的管道和烟囱中氯化氢（HCl）的质量浓度。它描述了采样和气体调节系统。 本文件规定了使用红外测量方法的便携式自动测量系统（P-AMS）要确定的特性和要满足的性能标准。它适用于定期监测和校准或控制永久安装在烟囱上的自动测量系统（AMS），用于监管或其他目的。 本文件中所述的红外测量方法可作为SRM使用，前提是该方法的扩展不确定度相对于日排放限值（ELV）小于20%，或对于ELV低于5 mg/m3的情况，其扩展不确定度小于1 mg/m3，以及与EN 15267中所述性能特征相关的标准- 4对于便携式自动测量系统（P-AMS），满足。 本文件规定了通过应用EN 14793证明替代方法（AM）与SRM等效的标准。

This document specifies the standard reference method (SRM) based on an automatic method for determination of the mass concentration of hydrogen chloride (HCl) in ducts and stacks emitting to the atmosphere. It describes the sampling and gas conditioning system. This document specifies the characteristics to be determined and the performance criteria to be fulfilled by portable automated measuring systems (P-AMS) using the infrared measurement method. It applies for periodic monitoring and for the calibration or control of automated measuring systems (AMS) permanently installed on a stack, for regulatory or other purposes. The infrared measurement method described in this document can be used as a SRM, provided the expanded uncertainty of the method is less than 20 % relative at the daily Emission Limit Value (ELV), or 1 mg/m3 for ELV below 5 mg/m3, and the criteria associated to performance characteristics described in EN 15267-4 for portable automated measuring systems (P-AMS), are fulfilled. This document specifies criteria for demonstration of equivalence of an alternative method (AM) to the SRM by application of EN 14793.
