European foreword
This document (CEN/TS 17405:2020) has been prepared by Technical Committee CEN/TC 264 “Air
quality”, the secretariat of which is held by DIN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
According to the CEN/CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United
Kingdom.
1 Scope
This document specifies the reference method (RM) for the measurement of carbon dioxide (CO ) based
on the infrared (IR) absorption principle. It includes the sampling and the gas conditioning system, and
allows the determination of the CO in flue gases emitted to the atmosphere from ducts and stacks. This
document specifies the measurement of the total CO concentration and does not differentiate between
biogenic and fossil derived CO .
This document specifies the characteristics to be determined and the performance criteria to be fulfilled
by portable automated measuring systems (P-AMS) using the IR 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.

SRM
reference method prescribed by European or national legislation
[SOURCE: EN 15259:2007]
3.2
reference method
RM
measurement method taken as a reference by convention, which gives the accepted reference value of
the measurand
Note 1 to entry: A reference method is fully described.
Note 2 to entry: A reference method can be a manual or an automated method.
Note 3 to entry: Alternative methods can be used if equivalence to the reference method has been
demonstrated.

method described in a written procedure containing all the means and procedures required to sample
and analyse, namely field of application, principle and/or reactions, definitions, equipment, procedures,
presentation of results, other requirements and measurement report

samples (e.g. probe, sample gas lines, flow meters and regulator, delivery pump) and for sample conditioning (e.g.
dust filter, pre-separator for interferents, cooler, converter). This definition also includes testing and adjusting
devices that are required for functional checks and, if applicable, for commissioning.
