Introduction
This document describes the quality assurance procedures related to Automated Measuring Systems (AMS)
for the determination of dust in flue gas, in order to meet the uncertainty requirements on measured values
given by regulations, e.g. EC Directives ([1], [2]), national or other legislation.
This document is only applicable in conjunction with the general document on quality assurance of AMS
described in EN 14181, and provides indications which are specific to dust measurements.
The calibration and validation of dust AMS are performed by parallel measurements with the reference
manual gravimetric method described in EN 13284-1.
1 Scope
This document specifies specific requirements on automated measuring systems (AMS) for dust monitoring. It
is derived from EN 14181 which is the general document on the quality assurance of AMS. It is only applicable
in conjunction with EN 14181.
This document specifies test criteria for the QAL1 and specific requirements for QAL2, QAL3 and AST for dust
AMS used for proving that the dust emissions from a source are compliant with emission limits below
50 mg/m (standard conditions) in ducted gaseous streams. This document is applicable by direct correlation
with the standard reference method (SRM) described in EN 13284-1.
This document is primarily developed for emissions from waste incinerators. From a technical point of view, it
may be applied to other processes, for which measurement at an emission limit is required with defined
uncertainty.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 13284-1:2001 and EN 14181:2004
and the following apply.
3.1
dust
particles, of any shape, structure or density, dispersed in the gas phase at the sampling point conditions which
may be collected by filtration under specified conditions after representative sampling of the gas to be
analysed, and which remain upstream of the filter and on the filter after drying under specified conditions
[EN 13284-1:2001]
3.2
automated measuring system (AMS)
measuring system permanently installed on site for continuous monitoring of emissions
NOTE 1 An AMS is a 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.
[EN 14181:2004]
NOTE 3 For the purpose of this document, AMS means automated dust measuring system.
3.3
cross sensitivity
response of the AMS to determinants other than dust concentration
NOTE Cross sensitivity can be caused for example by particle characteristics (including size, material type, electric
charge, shape and moisture content), flow gas conditions (including velocity) and gas composition (including water vapour,
water droplets).
3.4
emission limit value (ELV)
limit value related to the uncertainty requirement
NOTE For the EU directives [1] and [2] it is the daily emission value that relates to the uncertainty requirement.
3.5
linearity (lack of fit)
systematic deviation, within the range of application, between the accepted value of a reference material
applied to the measuring system and the corresponding output signal from the AMS
NOTE Test for linearity is described in Annex B of EN 14181:2004.
3.6
limit of detection
minimum value of the measurand for which the measuring system is not in the basic state, with a stated
probability
NOTE The basic state is usually represented by zero reference material.
3.7
period of unattended operation
maximum interval of time for which the performance characteristics remain within a predefined range without
external servicing, e.g. refill, calibration, adjustment
3.8
reproducibility under field conditions (r)
measure of the agreement between two identical measuring systems applied in parallel in field tests at a level
confidence of 95 % using the standard deviation of the difference of the paired measurements:
r = t × s
n−1; 0,95 D
n
()x − x
∑ 1,i 2,i
i=1
s =

2n
where
r is the reproducibility under field conditions;
t is the two-sided Students t-factor at a confidence level of 95 % with a number of degrees of
n−1; 0,95
freedom n–1;
s is the standard deviation of the difference of paired measurements;
D
x is the ith measurement result of the first measuring system;
1, i
x is the ith measurement result of the second measuring system;
2, i
n is the number of parallel measurements
NOTE The reproducibility under field conditions is calculated from the half-hour averaged output signals during the
three-month period.
3.9
Standard Reference Method (SRM)
method described and standardised to define an air quality characteristic, temporarily installed on site for
verification purposes
[EN 14181:2004]
NOTE For the purposes of this document, the SRM is specified in EN 13284-1.
4 Principle
This document is derived from the general document on the quality assurance of AMS (EN 14181). It shall be
applied in conjunction with that document. This document only deals with the specific aspects related to dust
monitoring.
According to EN 14181, three different levels of quality assurance are defined, designated as Quality
Assurance Levels (QAL). These levels cover the suitability of an AMS for its measuring task (QAL1), the
validation of the AMS following its installation (QAL2), the control of the AMS during its ongoing operation on
an industrial plant (QAL3). An annual Surveillance Test (AST) is also defined.
5 AMS performance criteria for QAL1
The performance of the AMS shall be assessed in a suitability test referred to as QAL1. Suitability tests for an
AMS are usually carried out within the framework of certification or type approval procedures. The suitability
test comprises a separate laboratory test and a three-month field test in a typical application.
The requirements for the tests used in QAL1 are given in Table 1. These requirements shall be used until
general requirements on AMS are specified in a European Standard on AMS certification.
The manufacturer shall ensure that the delivered AMS has the same characteristics as the tested devices.
