Introduction
This CEN Technical Report provides supporting guidance on the application of EN 14181:2004. It is based on
the growing experiences with EN 14181:2004 throughout the CEN member countries. EN 14181:2004
specifies three levels of quality assurance (QAL), known as QAL1, QAL2 and QAL3 as well as an Annual
Surveillance Test (AST). This Technical Report explains the requirements of these levels of quality assurance
to achieve a consistent application of EN 14181:2004.
1 Scope
This CEN Technical Report provides guidance for applying the European Standard EN 14181:2004.
This CEN Technical Report provides guidance only on applying the quality assurance levels QAL1, QAL2 and
QAL3 as well as the Annual Surveillance Test (AST).
This CEN Technical Report is an informative document.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
air quality characteristic
one of the quantifiable properties relating to an air mass under investigation, for example, concentration of a
constituent
[EN 14181:2004, 3.1]
2.2
automated measuring system
AMS
measuring system permanently installed on site for continuous monitoring of emissions
[EN 14181:2004, 3.2]
NOTE 1 An AMS is the automated application of a monitoring method, which is traceable to a reference method.
NOTE 2 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, moisture removal devices,
converters, diluters). This definition also includes testing and adjusting devices that are required for regular functional
checks.
2.3
calibration function
linear relationship between the values of the SRM and the AMS with the assumption of a constant residual
standard deviation
[EN 14181:2004, 3.3]
NOTE The calibration function is established during QAL2 on stack gases.
2.4
competent authority
organisation which implements the requirements of EU Directives and regulates installations, which must
comply with the requirements of applicable European Standards
[EN 15267-1:2009, 3.3]
2.5
confidence interval (two-sided)
when T and T are two functions of the observed values such that, θ being a population parameter to be
1 2
estimated, the probability P (T ≤ θ ≤ T ) is at least equal to (1 – α) [where (1 – α) is a fixed number, positive
r 1 2
and less than 1], the interval between T and T is a two-sided (1 – α) confidence interval for θ
1 2
[EN 14181:2004, 3.5]
2.6
CUSUM chart
calculation procedure in which the amount of drift and change in precision is compared to the corresponding
uncertainty components which are obtained during QAL1
[EN 14181:2004, 3.6]
2.7
drift
monotonic change of the calibration function over stated period of unattended operation, which results in a
change of the measured value
[EN 14181:2004, 3.7]
NOTE This refers to a change in the response of the AMS to a determinant which does not change.
2.8
emission limit value
ELV
limit value related to the uncertainty requirement
[EN 14181:2004, 3.8]
NOTE For EU Directives it is the daily emission limit value that relates to the uncertainty requirement.
2.9
extractive AMS
AMS having the detection unit physically separated from the gas stream by means of a sampling system
[EN 14181:2004, 3.9]
2.10
instability
change in the measured value comprised of drift and dispersion resulting from the change in the calibration
function over a stated period of unattended operation, for a given value of the air quality characteristic
NOTE 1 Drift and dispersion specify the monotonic and stochastic change with time of the output signal, respectively.
NOTE 2 This refers to a change in the response of the AMS to a determinant which does not change.
NOTE 3 Adapted from EN 14181:2004, 3.10.
2.11
instrument reading
indication of the measured value directly provided by the AMS without using the calibration function
[EN 14181:2004, 3.11]
2.12
intrinsic uncertainty
uncertainty component originating from the AMS itself, independent of the installation
2.13
legislation
Directives, Acts, ordinances and regulations
[EN 14181:2004, 3.12]
2.14
measurand
particular quantity subject to measurement
[EN 14181:2004, 3.13]
2.15
measured value
estimated value of the air quality characteristic derived from an output signal
NOTE 1 This usually involves calculations related to the calibration process and conversion to required quantities.
NOTE 2 Adapted from EN 14181:2004, 3.14.
2.16
non-extractive AMS
AMS having the detection unit in the gas stream or in a part of it
[EN 14181:2004, 3.15]
2.17
outlier
observation that lies an abnormal distance from other values in a set of data, and therefore has a low
probability of being a valid data point
2.18
period of unattended operation
maximum admissible interval of time for which the performance characteristics will remain within a predefined
range without external servicing, e.g. refill, calibration, adjustment
[EN 14181:2004, 3.16]
2.19
peripheral AMS or SRM
measuring system or SRM used to gather the data required to convert the measured values to standard
reference conditions, i.e. AMS or SRM for moisture, temperature, pressure and oxygen
[EN 14181:2004, 3.17]
2.20
precision
closeness of agreement of results obtained from the AMS for successive zero readings and successive span
readings at defined time intervals
[EN 14181:2004, 3.18]
2.21
reference material
material simulating a known concentration of the input parameter, by use of surrogates and traceable to
national standards
NOTE Surrogates normally used are calibration gasses, gas cells, gratings or filters.
[EN 14181:2004, 3.19]
2.22
response time
time interval between the instant of a sudden change in the value of the input quantity to an AMS and the time
as from which the value of the output quantity is reliably maintained above 90 % of the correct value of
