BS EN 16429:2021

What is BS EN 16429 about? 

Part of responsible production is to monitor your emissions. BS EN 16429 specifies the standard reference method (SRM) based on an automatic method for the determination of the mass concentration of hydrogen chloride (HCl) in ducts and stacks emitting to the atmosphere. BS EN 16429 describes the sampling and gas conditioning system. 

BS EN 16429 specifies the criteria for the demonstration of equivalence of an alternative method (AM) to the SRM. 

Note: BS EN 16429 applies for periodic monitoring and the calibration or control of automated measuring systems (AMS) permanently installed on a stack, for regulatory or other purposes. 

Who is BS EN 16429 for? 

BS EN 16429 on stationary source emissions is useful for: 

• Environmental regulatory bodies  
• Industrial installations emitting gases  
• Scientists studying pollution 
• Laboratories  

Why should you use BS EN 16429? 

BS EN 16429 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.  

BS EN 16429 specifies a method for the determination of the mass concentration of hydrogen chloride (HCl) in ducts and stacks emitting to the atmosphere using an automatic analyser using the infrared absorption principle. 

What’s changed since the last update? 

BS EN 16429:2021 supersedes CEN/TS 16429:2013 which is withdrawn. BS EN 16429:2021 includes some technical changes with respect to CEN/TS 16429:2013. These include:   

• Clause 6 "Analyser equipment": The description of the analyser equipment has been replaced by the reference to performance criteria given in EN 15267-4. 
• The informative Annex "Examples of schematics of non-dispersive infrared spectrometer" was deleted. 
• The informative Annex "Validation of the method in the field" was added.
