Stationary source emissions - Quality assurance and quality control procedures for automated dust arrestment plant monitors
This document specifies the quality assurance and quality control procedures related to automated dust arrestment plant monitors.
This document applies to two types of instruments commonly used for dust arrestment plant control purposes:
— filter dust monitors that are configured in mass concentration units (e.g. mg/m3) and is used for dust arrestment control purposes;
— filter leakage monitors that indicate a change in the emission levels or a change in the magnitude of the dust pulses created by the cleaning process of the dust arrestment plant.
This document applies to instruments certified according to the requirements of EN 15859.
This document provides information on the configuration, ongoing quality assurance (with internal zero and reference checks) and annual surveillance tests of instruments. This ensures that the instrument is providing information to demonstrate that dust arrestment plant is working correctly and controlling dust pollution to the required levels.
The configuration of the alarm levels of filter dust monitors is performed by parallel measurements with the standard reference method according to EN 13284-1.
This document specifies the set-up of filter leakage monitors used to monitor a change in response caused by deterioration in the operation of the dust arrestment plant.

Introduction
The type of monitoring of dust emissions at industrial plants depends on the monitoring objectives. In
general, three monitoring objectives can be distinguished:
— Monitoring of plants with emission limit values (ELV), which require quantitative measurements
with permanently installed automated measuring systems (AMS) providing measured values with a
maximum permissible measurement uncertainty specified by legislation, in order to determine
exceedances of the ELV and number of exceedances for specified time periods forms the first level of
monitoring. Large combustion plants and waste incineration plants are examples of plants under this
monitoring objective. The measurements are performed with AMS, which are performance tested
and certified according to EN 15267-1, EN 15267-2 and EN 15267-3. The quality assurance measures
for these AMS are laid down in EN 14181 and EN 13284-2.
— Monitoring of plants with ELV, which require qualitative measurements in order to demonstrate that
the dust emissions are below the specified ELV and the dust arrestment plant works properly form
the second level of monitoring. Foundries are typical examples of plants under this monitoring
objective. The measurements are performed with filter dust monitors, which can be calibrated in
3
mass concentration units (e.g. mg/m ) but have a larger measurement uncertainty than quantitative
measurements. Filter dust monitors are performance tested and certified according to EN 15859.
The quality assurance measures for these instruments are laid down in this document.
— Monitoring of dust arrestment plants with indicative measurements in order to indicate a possible
problem with the dust arrestment plant by monitoring a change in the emissions level or a change in
the magnitude of the dust pulses created by the cleaning process forms the third level of monitoring.
The measurements are performed with filter leakage monitors which are performance tested and
certified according to EN 15859. The quality assurance measures for these instruments are laid down
in this document.
This document provides supporting information on the quality assurance and quality control procedures
related to automated dust arrestment plant monitors, which cover both filter dust monitors and filter
leakage monitors.
For the purposes of this document, the term instrument is used to encompass both types of automated
dust arrestment plant monitors. The terms filter dust monitor and filter leakage monitor are only used
where it is necessary to distinguish between the two types.
This document includes provisions for the selection, installation, configuration, ongoing quality
assurance and annual surveillance test of automated dust arrestment plant monitors.
This document supports requirements for filter leakage monitors and filter dust monitors specified e.g.
in national legislation or in a number of industrial sector BREF Documents.

1 Scope
This document specifies the quality assurance and quality control procedures related to automated dust
arrestment plant monitors.
This document applies to two types of instruments commonly used for dust arrestment plant control
purposes:
3
— filter dust monitors that are configured in mass concentration units (e.g. mg/m ) and are used for
dust arrestment control purposes;
— filter leakage monitors that indicate a change in the emission levels or a change in the magnitude of
the dust pulses created by the cleaning process of the dust arrestment plant.
This document applies to instruments certified according to the requirements of EN 15859.
This document provides information on the configuration, ongoing quality assurance (with automatic
internal zero point and reference point checks) and annual surveillance tests of instruments. This ensures
that the instrument is providing information to demonstrate that the dust arrestment plant is working
correctly and controlling dust pollution to the required levels.
The configuration of the alarm levels of filter dust monitors is performed by parallel measurements with
the standard reference method in EN 13284-1.
This document specifies the set-up of filter leakage monitors used to monitor a change in response caused
by deterioration in the operation of the dust arrestment plant.

5 Principle
This document deals with quality assurance and quality control related to filter dust monitors and filter
leak monitors used on industrial plants for monitoring and controlling dust abatement systems.
The following four levels of quality assurance are required:
— selection and installation of a suitable instrument for the measurement task;
— configuration of the instrument;
— ongoing quality assurance of the instrument during its operation on an industrial plant by internal
fault detection;
— annual surveillance test of the instrument.
6 Selection and installation of a suitable instrument
6.1 Selection
This document shall be used with instruments that are certified according to EN 15859.
AMS that are certified according to EN 15267-1, EN 15267-2 and EN 15267-3 may also be used in
accordance with this document.
The application suitability of an instrument shall be considered when selecting an instrument for a
particular dust arrestment plant.

---------------------- Page: 12 ----------------------
SIST EN 17389:2020
EN 17389:2020 (E)
6.2 Installation
The location of the instrument shall be chosen taking into account the measurement objective, the
principle of detection of the instrument and the manufacturer’s recommendations.
Filter dust monitors shall be installed in a location with stable flow profile without vortexing and
backflow.
NOTE These conditions are generally fulfilled in sections of duct with at least five hydraulic diameters of
straight duct upstream of the measurement plane and two hydraulic diameters downstream (five hydraulic
diameters from the top of a stack).
Filter dust monitors shall be located to ensure that there is no interference between the measurement
results of the instrument and the results of the SRM measurements.
The working platform(s) for the instrument shall provide suitable and safe access to allow frequent
inspection and implementation of the quality assurance procedure. EN 15259 specifies criteria for
working platforms.
7 Configuration of instruments
7.1 General
The instrument shall be serviced, according to the manufacturer’s instructions, within 28 days before the
configuration procedure is carried out.
NOTE The plant operator is responsible for organizing the service of the instrument.
It is recommended to include the service report as an appendix to the configuration report.
7.2 Configuration of filter dust monitors
7.2.1 General
The principle of the configuration shall be as follows:
a) service test (see 7.2.2);
b) parallel measurements with the SRM (see 7.2.3);
c) setting of dust alarm limits (see 7.2.4).
The configuration procedure shall be repeated at least every three years and after a significant change to
the plant or filter dust monitor.
7.2.2 Service test
Service and service test shall be performed according to the manufacturer’s instructions. It should
contain at least:
a) cleaning critical components;
b) checking the correct functioning of the automatic internal zero point and reference point checks;
c) performing checks and procedures that are specified by the manufacturer and approved during the
performance test;
d) carrying out zero test according to the manufacturer's specifications (demonstrating that the
instrument output is zero, when no dust is present);
11
---------------------- Page: 13 ----------------------
SIST EN 17389:2020
EN 17389:2020 (E)
e) confirming, according to manufacturer’s specifications, that the instrument responds to dust (where
applicable, review historical data and alarm logs to ensure instrument is tracking known process
events, or monitor dust pulses associated with filter cleaning as shown in Annex B, Figure B.1);
f) checking components (including air purge) that minimize contamination.
All service tests results shall be recorded in a service report.
7.2.3 Parallel measurements with the SRM
Parallel measurements shall be performed with the filter dust monitor and the SRM in order to configure
the filter dust monitor. The SRM measurements shall be performed according to EN 13284-1.
The test laboratory performing the SRM measurements shall demonstrate their competence in
performing the measurements.
NOTE 1 Competence can be demonstrated by accreditation according to EN ISO/IEC 17025, or by direct
approval by the competent authority.
The SRM measurements shall be performed at a measurement plane in a duct, which fulfils the
requirements of EN 15259, and is as close as possible to the filter dust monitor, while taking into account
that the presence of the SRM equipment shall not influence or disturb the filter dust monitor
measurements and vice versa.
In order to ensure that the configuration is valid for the range of conditions within which the plant will
operate, the concentrations during the configuration shall be varied within the normal operation of the
plant. This shall ensure that the configuration of the filter dust monitor is valid over as large a range as
possible, and also that it covers most operational situations.
NOTE 2 Careful measurement planning can identify the optimum time for the parallel measurements, when the
emissions are at their highest.
The dust concentrations are often close to zero compared to the ELV, if the dust cleaning equipment of
the plant is operating normally. The measurement range can be extended in some cases by increasing the
dust concentration. This can be achieved by e.g. changing the plant load, lowering the efficiency of the gas
cleaning equipment, or by injecting dust of the same physical properties and ensuring homogeneous
concentration across the measurement planes of the filter dust monitor and the SRM (see Annex A). The
approach shall be selected by the test laboratory and agreed with both the plant operator and the
competent authority and be fully documented in the configuration report.
At least 6 valid parallel measurements with a sampling duration of 30 min each or at least 3 valid parallel
measurements with a sampling duration of 1 h each shall be performed in a measurement range, where
the instrument is responding to dust (this means that it has an output that is not zero or noise), over one
or more consecutive days. The total sampling duration shall be at least 3 h. The sampling duration of the
individual measurements shall be selected by the test laboratory taking into account e.g. the dust
concentration level and the limit of quantification of the SRM as well as legal requirements.
This document requires valid data points over a total sampling duration of at least 3 h. If data points are
excluded as invalid in the data evaluation, this requirement can be failed. It is therefore recommended
that addit

Introduction
The type of monitoring of dust emissions at industrial plants depends on the monitoring objectives. In
general, three monitoring objectives can be distinguished:
— Monitoring of plants with emission limit values (ELV), which require quantitative measurements
with permanently installed automated measuring systems (AMS) providing measured values with a
maximum permissible measurement uncertainty specified by legislation, in order to determine
exceedances of the ELV and number of exceedances for specified time periods forms the first level of
monitoring. Large combustion plants and waste incineration plants are examples of plants under this
monitoring objective. The measurements are performed with AMS, which are performance tested
and certified according to EN 15267-1, EN 15267-2 and EN 15267-3. The quality assurance measures
for these AMS are laid down in EN 14181 and EN 13284-2.
— Monitoring of plants with ELV, which require qualitative measurements in order to demonstrate that
the dust emissions are below the specified ELV and the dust arrestment plant works properly form
the second level of monitoring. Foundries are typical examples of plants under this monitoring
objective. The measurements are performed with filter dust monitors, which can be calibrated in
3
mass concentration units (e.g. mg/m ) but have a larger measurement uncertainty than quantitative
measurements. Filter dust monitors are performance tested and certified according to EN 15859.
The quality assurance measures for these instruments are laid down in this document.
— Monitoring of dust arrestment plants with indicative measurements in order to indicate a possible
problem with the dust arrestment plant by monitoring a change in the emissions level or a change in
the magnitude of the dust pulses created by the cleaning process forms the third level of monitoring.
The measurements are performed with filter leakage monitors which are performance tested and
certified according to EN 15859. The quality assurance measures for these instruments are laid down
in this document.
This document provides supporting information on the quality assurance and quality control procedures
related to automated dust arrestment plant monitors, which cover both filter dust monitors and filter
leakage monitors.
For the purposes of this document, the term instrument is used to encompass both types of automated
dust arrestment plant monitors. The terms filter dust monitor and filter leakage monitor are only used
where it is necessary to distinguish between the two types.
This document includes provisions for the selection, installation, configuration, ongoing quality
assurance and annual surveillance test of automated dust arrestment plant monitors.
This document supports requirements for filter leakage monitors and filter dust monitors specified e.g.
in national legislation or in a number of industrial sector BREF Documents.

1 Scope
This document specifies the quality assurance and quality control procedures related to automated dust
arrestment plant monitors.
This document applies to two types of instruments commonly used for dust arrestment plant control
purposes:
— filter dust monitors that are configured in mass concentration units (e.g. mg/m3) and is used for dust
arrestment control purposes;
— filter leakage monitors that indicate a change in the emission levels or a change in the magnitude of
the dust pulses created by the cleaning process of the dust arrestment plant.
This document applies to instruments certified according to the requirements of EN 15859.
This document provides information on the configuration, ongoing quality assurance (with internal zero
and reference checks) and annual surveillance tests of instruments. This ensures that the instrument is
providing information to demonstrate that dust arrestment plant is working correctly and controlling
dust pollution to the required levels.
The configuration of the alarm levels of filter dust monitors is performed by parallel measurements with
the standard reference method in EN 13284-1.
This document specifies the set-up of filter leakage monitors used to monitor a change in response caused
by deterioration in the operation of the dust arrestment plant.

5 Principle
This document deals with quality assurance and quality control related to filter dust monitors and filter
leak monitors used on industrial plants for monitoring and controlling dust abatement systems.
The following four levels of quality assurance are required:
— selection and installation of a suitable instrument for the measurement task;
— configuration of the instrument;
— ongoing quality assurance of the instrument during its operation on an industrial plant by internal
fault detection;
— annual surveillance test of the instrument.
6 Selection and installation of a suitable instrument
6.1 Selection
This document shall be used with instruments that are certified according to EN 15859.
AMS that are certified according to EN 15267-1, EN 15267-2 and EN 15267-3 may also be used in
accordance with this document.
The application suitability of an instrument shall be considered when selecting an instrument for a
particular dust arrestment plant.
6.2 Installation
The location of the instrument should be chosen taking into account the measurement objective, the
principle of detection of the instrument and the manufacturer’s recommendations.
Filter dust monitors should be installed in a location with stable flow profile without vortexing and
backflow.
NOTE These conditions are generally fulfilled in sections of duct with at least five hydraulic diameters of
straight duct upstream of the measurement plane and two hydraulic diameters downstream (five hydraulic
diameters from the top of a stack).
Filter dust monitors should be located to ensure that there is no interference between the measurement
results of the instrument and the results of the SRM measurements.
The working platform(s) for the instrument should provide suitable and safe access to allow frequent
inspection and implementation of the quality assurance procedure. EN 15259 specifies criteria for
working platforms.

7 Configuration of instruments
7.1 General
The instrument should be serviced, according to the manufacturer’s instructions, within 28 days before
the configuration procedure is carried out.
NOTE The plant operator is responsible for organizing the service of the instrument.
It is recommended to include the service report as an appendix to the configuration report.
7.2 Configuration of filter dust monitors
7.2.1 General
The principle of the configuration should be as follows:
a) service test (see 7.2.2);
b) parallel measurements with the SRM (see 7.2.3);
c) setting of dust alarm limits (see 7.2.4).
The configuration procedure shall be repeated at least every three years and after a significant change to
the plant or filter dust monitor.
7.2.2 Service test
Service and service test shall be performed according to the manufacturer’s instructions. It should
contain at least:
a) cleaning critical components;
b) checking self-check procedure;
c) performing manual checks that are required according to the performance test report;
d) carrying out zero test according to the manufacturer's specifications (demonstrating that the
instrument output is zero, when no dust is present);
e) confirming, according to manufacturer’s specifications, that the instrument responds to dust (where
applicable, review historical data and alarm logs to ensure instrument is tracking known process
events, or monitor dust pulses associated with filter cleaning as shown in Figure A.1);
f) checking components (including air purge) that minimize contamination.
All service tests results should be recorded in a service report.
7.2.3 Parallel measurements with the SRM
Parallel measurements shall be performed with the filter dust monitor and the SRM in order to configure
the filter dust monitor. The SRM measurements shall be performed according to EN 13284-1.
The test laboratory performing the SRM measurements shall demonstrate their competence in
performing the measurements.
NOTE 1 Competence can be demonstrated by accreditation according to EN ISO/IEC 17025, or by direct
approval by the competent authority.
11
---------------------- Page: 13 ----------------------
oSIST prEN 17389:2019
prEN 17389:2019 (E)
The SRM measurements shall be performed at a measurement plane in a duct, which fulfils the
requirements of EN 15259, and is as close as possible to the filter dust monitor, while taking into account
that the presence of the SRM equipment shall not influence or disturb the filter dust monitor
measurements and vice versa.
In order to ensure that the configuration is valid for the range of conditions within which the plant will
operate, the concentrations during the configuration shall be varied within the normal operation of the
plant. This shall ensure that the configuration of the filter dust monitor is valid over as large a range as
possible, and also that it covers most operational situations.
NOTE 2 Careful measurement planning can identify the optimum time for the parallel measurements, when the
emissions are at their highest.
The dust concentrations are often close to zero compared to the ELV, if the dust cleaning equipment of
the plant is operating normally. The measurement range can be extended in some cases by increasing the
dust concentration. This can be achieved by e.g. changing the plant load, lowering the efficiency of the gas
cleaning equipment, or by injecting dust of the same physical properties and ensuring homogeneous
concentration across the measurement planes of the filter dust monitor and the SRM (see Annex A). The
approach shall be selected by the test laboratory and agreed with both the plant operator and the
competent authority and be fully documented in the configuration report.
At least 6 valid parallel measurements with a sampling duration of 30 min each or at least 3 valid parallel
measurements with a sampling duration of 1 h each shall be performed in a measurement range, where
the instrument is responding to dust (this means that it has an output that is not zero or noise), over one
or more consecutive days. The total sampling duration shall be at least 3 h. The sampling duration of the
individual measurements shall be selected by the test laboratory taking into account e.g. the dust
concentration level and the limit of quantification of the SRM as well as legal requirements.
This document requires valid data points over a total sampling duration of at least 3 h. If data points are
excluded as invalid in the data evaluation, this requirement can be failed. It is therefore recommended
that additional data points be taken, to allow for the exclusion of invalid data pairs.
During the parallel measurements with the filter dust monitor and the SRM, each result is considered as
a measurement pair (one filter dust monitor reading and one SRM measured value) and these shall cover
the same time period.
The SRM measured results shall be expressed at standard conditions for temperature and pressure and,
where required for water vapour.
The filter dust monitor output signal, which can be analogue or digital, should be continuously recorded
during the parallel measurements in order to be electronically averaged. Data recording intervals and
averaging times should be reported specifically in the configuration report. To avoid errors from aliasing,
analogue signals should be digitised with a sampling rate of at least four samples within the response
time of the instrument. The recording system shall have an averaging time significantly shorter than the
response time of the instrument.
A set of measurements is valid when all of the requirements below are fulfilled:
— the SRM measurements are performed according to EN 13284-1;
— the time period of each filter dust monitor reading is larger than 90 % of the averaging time
(excluding all output signals which are outside the measuring range, signals obtained during internal
checks, and signals obtained during any other malfunctioning of the monitor).
