This document describes a method for sampling and determining the concentration of gaseous emissions to atmosphere of multiple species from ducts and stacks by extractive Fourier transform infrared (FTIR) spectroscopy. This method is applicable to periodic monitoring and to the calibration or control of automated measuring systems (AMS) permanently installed on a stack, for regulatory or other purposes.Cross References:EN ISO 14956ISO 14956GUM:1995EN 14793:2017EN 15267-4:2017ISO/IEC Guide 98-3:2008EN 15259:2007JCGM 200:2012ISO/IEC 17025EN ISO/IEC 17025ISO 21258:2010EN ISO 25139:2011EN 14791:2017EN 1911:2010EN 14792:2017ISO 25139:2011EN 15058:2017EN 14789:2017EN ISO 21258:2010EN 14790:2017All current amendments available at time of purchase are included with the purchase of this document.
