Stationary source emissions - Determination of low range mass concentration of dust - Part 1: Manual gravimetric method

This European Standard specifies a reference method for the measurement of low dust concentration in ducted gaseous streams in the concentrations below 50 mg/m3 at standard conditions. This European Standard is primarily developed and validated for gaseous streams emitted by waste incinerators. More generally, it may be applied to gases emitted from stationary sources, and to higher concentrations. If the gases contain unstable, reactive or semi-volatile substances, the measurement depends on the sampling and filter treatment conditions. This method has been validated in field tests with special emphasis to dust concentrations around 5 mg/m3. The results of the field tests are presented in Annex A.

Emissionen aus stationären Quellen - Ermittlung der Staubmassenkonzentration bei geringen Staubkonzentrationen - Teil 1: Manuelles gravimetrisches Verfahren

Diese Europäische Norm legt das Standardreferenzverfahren (SRM) zur Messung geringer Staubkonzentrationen in geführten Gasströmen im Konzentrationsbereich unterhalb von 50 mg/m3 bei Normbedingungen fest.
Diese Europäische Norm wurde in erster Linie zur Untersuchung der Abgasströme von Abfallverbrennungsanlagen entwickelt und validiert. Darüber hinaus kann sie auch auf Abgase von anderen stationären Quellen und bei höheren Konzentrationen angewandt werden.
Falls die Abgase instabile, reaktive oder halbflüchtige Stoffe enthalten, hängt die Messung von den Bedingungen der Probenahme und Filterbehandlung ab.
Dieses Verfahren wurde in Feldversuchen insbesondere für den Konzentrationsbereich um 5 mg/m3 validiert. Die Ergebnisse der Feldversuche sind in Anhang A dargestellt.

Emissions de sources fixes - Détermination de la faible concentration en masse de poussières - Partie 1 : Méthode gravimétrique manuelle

La présente Norme européenne spécifie la méthode de référence normalisée (SRM) pour le mesurage de faibles concentrations de poussières, inférieures à 50 mg/m3 dans les conditions normales, dans des effluents gazeux canalisés.
La présente Norme européenne est principalement élaborée et validée pour les effluents gazeux d’incinérateurs de déchets. De manière plus générale, elle peut s'appliquer aux gaz émis par d’autres sources fixes et à des concentrations plus élevées.
Lorsque les gaz contiennent des substances instables, réactives ou semi-volatiles, le mesurage dépend des conditions de prélèvement et de traitement des filtres.
Cette méthode a été validée lors d’essais sur site, qui ont porté plus particulièrement sur les concentrations en poussières voisines de 5 mg/m3. Les résultats des essais sur site sont présentés à l'Annexe A.

Emisije nepremičnih virov - Določevanje nizkih masnih koncentracij prahu - 1. del: Ročna gravimetrijska metoda

Ta evropski standard določa referenčno metodo za merjenje nizke koncentracije prahu v odvodnikih plinskih tokov pri koncentracijah, nižjih od 50 mg/m3, pri standardnih pogojih. Ta evropski standard je bil razvit in potrjen predvsem za plinske tokove sežigalnic odpadkov. Na splošno se lahko uporablja za pline nepremičnih virov in pri večjih koncentracijah prahu. Če plini vsebujejo nestabilne, reaktivne ali polhlapne snovi, je meritev odvisna od pogojev vzorčenja in obdelave filtra. Ta metoda je bila potrjena s terenskimi preskusi, pri čemer je bila posebna pozornost namenjena koncentracijam prahu okoli 5 mg/m3. Rezultati terenskih preskusov so predstavljeni v dodatku A.

This European Standard is primarily developed and validated for gaseous streams emitted by waste

incinerators. More generally, it can be applied to gases emitted from other stationary sources, and to

higher concentrations.

If the gases contain unstable, reactive or semi-volatile substances, the measurement depends on the

5 Principle

A sample stream of the gas is extracted from the main gas stream at representative measurement points

for a measured period of time, with an isokinetically controlled flow rate and a measured volume. The

dust entrained in the gas sample is separated by a pre-weighed plane filter, which is then dried and re-

weighed. Deposits upstream of the filter in the sampling system are also recovered and weighed. The

increase of mass of the filter and the deposited mass upstream the filter are attributed to dust collected

from the sampled gas, which allows the dust concentration to be calculated.

Two different configurations of the sampling system may be used depending on the characteristics of

gases to be sampled (see 7.2.2).
Valid measurements can be achieved only when:

a) the gas stream in the duct at the measurement site (sampling location) has a sufficiently steady

velocity profile (see EN 15259);

b) sampling is carried out without disturbance of the gas stream with a sharp edged nozzle facing into

the stream under isokinetic conditions;
---------------------- Page: 12 ----------------------
SIST EN 13284-1:2018
EN 13284-1:2017 (E)

c) samples are taken at a pre-selected number of stated positions in the measurement plane, to allow

for a non-uniform distribution of dust in the duct;

d) the sampling system is designed and operated to avoid condensation, chemical reactions and to

minimize dust deposits upstream of the filter and to be leak free;

e) sampling is carried out at an appropriate filtration temperature, e.g. stack temperature or at least the

recommended temperature of 160 °C (see Annex H);
f) dust deposits upstream of the filter are taken into account;

g) the field blank value does not exceed 10 % of the lowest emission limit value set for the process or

0,5 mg/m , whichever is greater;

h) the sampling and weighing procedures are adapted to the expected dust quantities;

i) the expanded uncertainty calculated by means of an uncertainty budget does not exceed the

corresponding specification in the measurement objective. For regulatory purposes the expanded

uncertainty shall not exceed 20 % of the emission limit value specified by the authorities unless

specified otherwise by the competent authorities.

NOTE The IED e.g. specifies a maximum permissible uncertainty of 30 % of the daily emission limit value (ELV)

for automated dust measuring systems. This requires that the expanded uncertainty of the SRM is lower for

calibration purposes.

Annex D provides a summary of the requirements for the application of this measurement method.

6 Measurement planning and sampling strategy
6.1 Measurement planning

Emission measurements at a plant shall be carried out such that the results are representative of the

emissions from this plant for operating conditions specified in the measurement objective and

comparable with results obtained for other comparable plants. Therefore, dust measurements shall be

planned in accordance with EN 15259.

Before carrying out any measurements, the purpose of the sampling and the sampling procedures shall

be discussed with the plant personnel concerned. The nature of the plant process, e.g. steady-state or

cyclic, can affect the sampling programme. If the process can be performed in a steady-state, it is

important that this is maintained during sampling.

Dates, starting times, duration of survey and sampling periods as well as plant operating conditions

during these periods shall be agreed with the plant management.

Preliminary calculations shall be made on the basis of expected dust concentration in order to verify that

expected sampled dust quantities are consistent with attainable field blank values, and that no

overloading of the filter occurs (see Annex E).

For sampling duration limited to 30 min, required for certain trial or regulatory purposes, the uncertainty

of measurement can increase due to the limited sample volume. Furthermore, completion of sampling

along two diameters within 30 min, even for medium size ducts, can require simultaneous sampling with

two or more sampling systems.

Where possible, the sampling duration can be extended, which decreases the quantification limit and

improves the measurement uncertainty (see Annex E). The sampling duration should be selected, to

minimize the effect of non-steady-state conditions of the stationary source.
