Foreword
This document (EN 14181:2014) has been prepared by Technical Committee CEN/TC 264 “Air quality”, the
secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by May 2015 and conflicting national standards shall be withdrawn at the
latest by May 2015.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 14181:2004.
Annex J provides details of significant technical changes between this European Standard and the previous
edition.
The first edition of this document has been prepared under a mandate given to CEN by the European
Commission and the European Free Trade Association to support requirements in the EU Directives
2000/76/EC [1] and 2001/80/EC [2], which have been replaced by EU Directive 2010/75/EU [3], and may also
be applicable for other purposes.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech
Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece,
Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal,
Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
Introduction
This European Standard describes the quality assurance procedures needed to assure that an automated
measuring system (AMS) installed to measure emissions to air are capable of meeting the uncertainty
requirements on measured values given by legislation, e.g. EU Directives [1], [2], [3] or national legislation, or
more generally by competent authorities.
Three different quality assurance levels (QAL1, QAL2, and QAL3) are defined to achieve this objective. These
quality assurance levels cover the suitability of an AMS for its measuring task (e.g. before or during the
purchase period of the AMS), the validation of the AMS following its installation, and the control of the AMS
during its ongoing operation on an industrial plant. An annual surveillance test (AST) is also defined.
The suitability evaluation (QAL1) of the AMS and its measuring procedure are described in EN 15267-3 and
EN ISO 14956 where a methodology is given for calculating the total uncertainty of AMS measured values.
This total uncertainty is calculated from the evaluation of all the uncertainty components arising from its
individual performance characteristics that contribute.
1 Scope
This European Standard specifies procedures for establishing quality assurance levels (QAL) for automated
measuring systems (AMS) installed on industrial plants for the determination of the flue gas components and
other flue gas parameters.
This European Standard specifies:
— a procedure (QAL2) to calibrate the AMS and determine the variability of the measured values obtained
by it, so as to demonstrate the suitability of the AMS for its application, following its installation;
— a procedure (QAL3) to maintain and demonstrate the required quality of the measurement results during
the normal operation of an AMS, by checking that the zero and span characteristics are consistent with
those determined during QAL1;
— a procedure for the annual surveillance tests (AST) of the AMS in order to evaluate (i) that it functions
correctly and its performance remains valid and (ii) that its calibration function and variability remain as
previously determined.
This European Standard is designed to be used after the AMS has been certified in accordance with the
series of European Standards EN 15267.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
automated measuring system
AMS
measuring system permanently installed on site for continuous monitoring of emissions or measurement of
peripheral parameters
Note 1 to entry: An AMS is a method which is traceable to a reference method.
Note 2 to entry: Apart from the analyser, an AMS includes facilities for taking samples (e.g. sample probe, sample gas
lines, flow meters, regulators, delivery pumps) and for sample conditioning (e.g. dust filter, water vapour removal devices,
converters, diluters). This definition also includes testing and adjusting devices that are required for regular functional
checks.
3.2
extractive AMS
AMS having the detection unit physically separated from the gas stream by means of a sampling system
3.3
in-situ AMS
AMS having the detection unit in the gas stream or in a part of it
3.4
peripheral AMS
AMS used to gather the data required to convert the AMS measured value to standard conditions
Note 1 to entry: A peripheral AMS is used to measure e.g. water vapour, temperature, pressure and oxygen.
3.5
reference method
RM
measurement method taken as a reference by convention, which gives the accepted reference value of the
measurand
[SOURCE: EN 15259:2007]
3.6
standard reference method
SRM
reference method prescribed by European or national legislation
Note 1 to entry: Standard reference methods are used e.g. to calibrate and validate AMS and for periodic
measurements to check compliance with limit values.
[SOURCE: EN 15259:2007]
3.7
peripheral SRM
SRM used to gather the data required to convert the SRM measured values to AMS or standard conditions
Note 1 to entry: A peripheral SRM is used to measure e.g. water vapour, temperature, pressure and oxygen.
3.8
standard conditions
conditions to which measured values have to be standardized to verify compliance with emission limit values
Note 1 to entry: Standard conditions are specified e.g. in EU Directives [1], [2] and [3].
3.9

ELV
limit value related to the maximum permissible uncertainty
Note 1 to entry: For the EU Directives [1], [2] and [3] it is the daily emission limit value that relates to the uncertainty
requirement.

maximum permissible uncertainty
uncertainty requirement on AMS measured values given by legislation or competent authorities
3.11
legislation
directives, acts, ordinances or regulations
3.12
competent authority
organization or organizations which implement the requirements of EU Directives and regulate installations
which shall comply with the requirements of this European Standard
3.13
calibration function
linear relationship between the values of the SRM and the AMS with the assumption of a constant residual
standard deviation
Note 1 to entry: For dust measuring AMS, a quadratic calibration function can be used as described in EN 132
