Description of BS EN 16429:2021 - TC 2021This 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 20Â % relative at the daily Emission Limit Value (ELV), or 1Â mg/m3 for ELV below 5Â 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 ENÂ 14793.
