scope:

This European Standard specifies specific requirements on automated measuring systems (AMS) for monitoring of total mercury. It is derived from EN 14181, which is the general document on the quality assurance of AMS. It is only applicable in conjunction with EN 14181. This European Standard sets specific requirements for the quality assurance levels and annual surveillance test as specified in EN 14181, for mercury AMS used for proving that the mercury emissions from a source are compliant with emission limits below 0,5 mg/m3 ) (standard conditions) in ducted gaseous streams. This European Standard is applicable by direct correlation with the standard reference method (SRM) described in EN 13211. This European Standard is primarily developed for emissions from waste incinerators. From a technical point of view, it may be applied to other processes, for which measurement at an emission limit is required with defined uncertainty.
