EN 15359:2011 (E) 4 Introduction The objective of this document is to provide unambiguous and clear classification and specification principles for solid recovered fuels (SRF). The document aims at serving as a tool to enable efficient trading of SRF, promoting their acceptability on the fuel market and increasing the public trust. The document will facilitate a good understanding between seller and buyer, facilitate purchase, transborder movements, use and supervision as well as a good communication with equipment manufacturers. It will also facilitate authority permission procedures and ease the reporting on the use of fuels from renewable energy sources and on other environmental issues. SRF are produced from non hazardous waste. The input waste can be production specific waste, municipal solid waste, industrial waste, commercial waste, construction and demolition waste, sewage sludge etc. It is thus obvious that SRF are a heterogeneous group of fuels. A well defined system for classification and specification is therefore of great importance to reach the above mentioned objectives and intentions. This document covers all types of SRF and will thus have a wide field of application. The purpose of producing a solid recovered fuel is to use it for energy generation at the highest possible energy efficiency. SRF can according to Article 6 of the Waste Framework Directive (2008/98/EC) cease to be waste at Community or national level if certain criteria are fulfilled. Until such legal decisions are taken SFR can be used in plants covered by the Directive 2000/76/EC. This document describes the compliance rules which SRF has to meet to be classified according to the classification system. It also describes how the supplier can establish a declaration of conformity to the different EN standards for SRF. Figure 1 illustrates a simplified flow chain for SRF, from input of waste to end use of SRF. This document has an interface to all the stages in the chain, but SRF classification and specification are applicable at the point of delivery as shown in the figure. Requirements for how the input waste is collected and how to use the fuel are not part of this document. SIST EN 15359:2012

When no preparation of the laboratory sample is required, the laboratory sample is the test sample. A test portion is removed from the test sample for the performance of the test or for analysis. NOTE 2 The laboratory sample is the final sample from the point of view of sample collection but it is the initial sample from the point of view of the laboratory. NOTE 3 Several laboratory samples may be prepared and sent to different laboratories or to the same laboratory for different purposes. When sent to the same laboratory, the set is generally considered as a single laboratory sample and is documented as a single sample. 3.8 lot defined quantity of fuel for which the quality is to be determined NOTE 1 See also sub-lot.

The characteristics are chosen to give a stakeholder an immediate but simplified picture of the fuel in question. Only fuels derived from non hazardous waste that meet the SRF European Standards can be classified as SRF. The classification itself is not enough for an intending user. A user has to have a more detailed description of the fuel. Relevant fuel properties are thus to be further specified. Some of the fuel properties are so important that they are obligatory to specify whereas others can be recorded voluntarily, e.g. upon request of the user. SIST EN 15359:2012



EN 15359:2011 (E) 9 It is important that SRF meet specified quality requirements which are to be determined based on a defined lot size by a minimum number of measurements. 6 Requirements and declaration of conformity In conformity with this document, SRF shall comply with the following requirements: a) SRF shall be classified according to the system in Clause 7; b) SRF shall meet quality requirements according to given compliance rules in Clause 8; c) SRF properties shall be specified according to Clause 9. The producer/supplier of solid recovered fuel shall give a declaration of conformity to this document. The record shall be kept available for inspection. A model template for the declaration is given in Annex C. NOTE General criteria for a supplier’s declaration is given in EN ISO/IEC 17050-1:2010 and
EN ISO/IEC 17050-2:2004. 7 Classification The classification system (Table 1) for SRF is based on limit values for three important fuel characteristics. These are: a) the mean value for net calorific value (ar); b) the mean value for chlorine content (d); c) the median and 80th percentile values for mercury content (ar). Each characteristic is divided into 5 classes. The SRF shall be assigned a class number from 1 to 5 for each characteristic. A combination of the class numbers makes up the class code (see example below). The characteristics are of equal importance and thus no single class number determines the code. The class code shall be included in the specification as described in Clause 9. Due to the statistical distribution pattern of the characteristics the values shall be presented as:  net calorific value (NCV) mean (arithmetic);  chlorine content (Cl)
mean (arithmetic);  mercury content (Hg)
median and 80th percentile. The higher of the two statistical values (median and 80th percentile) in a Hg data set determines the class. EXAMPLE A SRF with a median value of 0,03 and a 80th percentile value of 0,07 belongs to Hg class 3 (according to Table 1). For the determination of NCV EN 15400, for Cl EN 15408 and for Hg EN 15411 shall be used. NOTE 1 80th percentile is the value on or below which 80 % of the observations fall. NOTE 2 For details on statistics see CEN/TR 15508 [5]. NOTE 3 The averages and percentiles are determined on the quantity of SRF as specified in Clause 8. SIST EN 15359:2012



EN 15359:2011 (E) 10 NOTE 4 The classes have been determined as a tool for identifying and pre-selecting SRF. However, the performances of the plant where SRF is used are depending on the properties of the SRF and more significantly on the design and operating conditions of such a plant. NOTE 5 Not all kinds of SRF are suited for all types of installation (see CEN/TR 15508) [5]. For example, if 100 % SRF is used as fuel and an emission limit for Hg is defined at 0,05 mg/m3, for cement and lime kilns as well as for power plants, Class Hg 1 fuels would fit to all types of these. Class Hg 5 fuels could only be used in these processes if this class of fuel is less than 100 % of the fuel mix. For other classes the specific transfer factor of a given process and the proportion of SRF will determine which classes can be used without improvement of the transfer conditions. Examples of transfer factors for existing processes are given in CEN/TR 15508. NOTE 6 SRF should not be used as a fuel if there is less thermal energy produced from the combustion of the SRF and available for the process of the installation, than the energy used by the combustion of the SRF (thus not available for the process). This can, for example, prevent the use of class NCV 5 in installations requiring a higher minimum NCV for energy recovery.

Example of classification: The class code of a SRF having a mean net calorific value of 19 MJ/kg (ar), a mean chlorine content of 0,5 % (d) and a median mercury content of 0,016 mg/MJ (ar) with a 80th percentile value of 0,05 mg/MJ (ar) is designated as: Class code NCV 3; Cl 2; Hg 2. 8 Compliance rules 8.1 Compliance rules for classification The compliance rules for classification are illustrated by examples in Annex D. For a considered 12 months period, for each characteristic specified in the classification system, the compliance of a particular SRF shall be established by demonstration that the measured properties conform to the limit values defined for that class. This shall be performed at a period in which a quality management system (QMS) is applied. The maximum weight of a lot for classification shall be no more than 1 500 tonnes. When the 12 month production is less than 15 000 tonnes the lot size for classification shall be one tenth of the amount produced in a 12 months rolling period. SIST EN 15359:2012



EN 15359:2011 (E) 11 If there are significant changes in the properties of input materials or in the production process conditions, the production shall be considered to be interrupted. Significant here means such a change that would result in a change of class code. NOTE 1 If the classification cannot be based on a 12 month period of actual production, an estimation of the planned production of the missing month should be included in the rolling 12 month period. NOTE 2 A quality management system is meant as any systematic procedure used for complying with this European Standard. For each lot, at least one measurement of each characteristic shall be performed. An additional laboratory sample shall be taken in case of a cross check is needed. The laboratory sample shall be kept for a period of minimum 12 months. The sampling and sample procedure are illustrated in Figure 2. For sampling and sample reduction EN 15442 shall be applied. The comparison for NCV and Cl with the limit values of the classes is made by taking the 95 % confidence interval of the arithmetic mean of 10 measurements into account. For the calculation of the lower and the upper limit of the 95 % confidence interval of the arithmetic mean the following equation shall be used: nsXX⋅±=96,1 where X is the lower/upper limit of the 95 % confidence interval of the arithmetic mean; X is the arithmetic mean (based on all measurements); 96,1 is the functional characteristic of the normal distribution (for the 95 % confidence interval); s is the standard deviation (based on all measurements); n is the number of measurements (here n = 10). Decisive for the categorisation of the characteristic NCV is the calculated lower limit of the 95 % confidence interval of the arithmetic mean and for Cl the corresponding upper limit. The class code for Hg is established using median and 80th percentile based on data sets of 10 consecutive measurements.
If, at the end of the 12 month period, an incomplete data set exists (with less than 10 data), these data shall be used in the following 12 month period and be completed with the consecutive measurements of that period to a full data set of 10 measurements. In the case that for one characteristic to be classified several analyses of a 12 month period lead to different classification results, always the highest class has to be used for the determination of the class of the SRF (see Example 2 in D.2). After the start of the production of SRF or after a significant change, the minimum of 10 measurement results can be obtained on one or several lots as defined above. When several combined samples are taken on the same lot they shall be taken independently. For process control reasons it is recommended to calculate the median and the 80 percentile value after the measurement of every lot (e.g. for data sets No. 1 to No. 10 / No. 2 to No. 11 / etc.) and to consider the short time variation of the analytical results. Within the characterisation period it is recommended to use as a prediction method for virgin producers the 50 % - rule for Hg classification. This prediction method is working according to the principle of a conservative classification (indirect safety margin). SIST EN 15359:2012



EN 15359:2011 (E) 12 NOTE 3 If production time is less than 12 months it can be considered and treated as an initial phase of the production. NOTE 4 The 50 % rule means that classification is determined by comparing the measurement results to 50 % of the class limits (median and/or 80-percentile). For more details see CEN/TR 15508 [5]. 8.2 Compliance rules for specification The SRF specification to be agreed upon by the supplier and the user may define the lot size up to a maximum of 1 500 tonnes as well as by the compliance rules. In case these elements are not defined in the SRF specification, then the lot size and compliance rules specified for the classification apply.

(see EN 15442) 9 Specifications 9.1 General The SRF shall be specified according to the template in Annex A. The template is divided in two parts: Part 1 consists of properties that are obligatory to specify and Part 2 of properties that are voluntary to specify. The list of properties in Part 2 may be altered (new properties added and existing removed). For specification of the properties in Part 1 determination shall be made according to CEN test methods (Technical Specifications or European Standards). For the properties in Part 2 CEN test methods is recommended but other relevant methods may be used. If other methods are used it shall be stated in the (fuel) specification. SIST EN 15359:2012

SIST EN 15359 : 2012
Uvod
Namen tega dokumenta je zagotoviti nedvoumna in jasna načela za klasifikacijo in specifikacijo trdnih
alternativnih goriv (TAG). Dokument naj bi se uporabljal kot orodje za omogočanje učinkovitega
trgovanja s trdnimi alternativnimi gorivi, spodbujanje njihove sprejemljivosti na trgu goriv ter krepitev
zaupanja javnosti. Dokument bo olajšal razumevanje med prodajalcem in kupcem in poenostavil
nakup, čezmejna gibanja, uporabo in nadzor ter dobro komunikacijo s proizvajalci opreme. Olajšal bo
tudi postopke za pridobivanje dovoljenj pristojnih organov ter poročanje o uporabi goriv iz obnovljivih
virov energije in drugih okoljskih vprašanjih.
Trdna alternativna goriva se proizvajajo iz nenevarnih odpadkov. Vhodni odpadki so lahko posebni
odpadki iz proizvodnje, komunalni trdni odpadki, industrijski odpadki, gospodarski odpadki, gradbeni
odpadki in odpadki pri rušenju objektov, blato iz čistilnih naprav itd. Iz tega je razvidno, da so trdna
alternativna goriva raznolika skupina goriv. Dobro opredeljen sistem za klasifikacijo in specifikacijo je
zato zelo pomemben za doseganje zgoraj navedenih ciljev in namenov.
Ta dokument zajema vse vrste trdnih alternativnih goriv in bo tako imel široko področje uporabe.
Namen proizvodnje trdnih alternativnih goriv je njihova uporaba za pridobivanje energije z najvišjo
možno energijsko učinkovitostjo. V skladu s 6. členom Okvirne direktive o odpadkih (2008/98/ES)
lahko trdna alternativna goriva prenehajo biti odpadki na ravni Skupnosti ali nacionalni ravni, če so
izpolnjeni določeni kriteriji. Dokler se ne sprejmejo takšne pravne odločitve, se lahko trdna alternativna
goriva uporabljajo v napravah iz Direktive 2000/76/ES.
Ta dokument opisuje pravila skladnosti, ki jih morajo izpolnjevati trdna alternativna goriva, da se lahko
klasificirajo v skladu s sistemom klasifikacije. Opisuje tudi, kako lahko dobavitelj sestavi izjavo o
skladnosti z različnimi standardi EN za trdna alternativna goriva.
Slika 1 prikazuje poenostavljeno verigo poteka za trdna alternativna goriva, od vhoda odpadkov do
končne uporabe trdnih alternativnih goriv. Ta dokument je povezan z vsemi fazami v verigi, vendar se
klasifikacija in specifikacija trdnih alternativnih goriv uporabljata v točki dostave, kot je prikazano na
sliki. Zahteve v zvezi z načini zbiranja vhodnih odpadkov in uporabo goriva niso del tega dokumenta.

SIST EN 15359 : 2012
5 Načela
Sistem klasifikacije temelji na treh pomembnih karakteristikah, ki se nanašajo na glavne karakteristike
trdnih alternativnih goriv: ekonomska karakteristika (spodnja kalorična vrednost, tehnična
karakteristika (vsebnost klora) in okoljska karakteristika (vsebnost živega srebra). Karakteristike so
izbrane zato, da zainteresirana stran dobi takojšnjo, vendar poenostavljeno sliko o zadevnem gorivu.
Samo goriva iz nenevarnih odpadkov, ki izpolnjujejo evropske standarde o trdnih alternativnih gorivih,
so lahko klasificirana kot trdna alternativna goriva.
Sama klasifikacija ni dovolj za zainteresiranega uporabnika. Uporabnik mora imeti podrobnejši opis
goriva. Ustrezne lastnosti goriva je zato treba dodatno navesti. Nekatere lastnosti goriva so tako
pomembne, da jih je treba obvezno navesti, druge pa se lahko navedejo prostovoljno, npr. na zahtevo
uporabnika.
Pomembno je, da trdna alternativna goriva izpolnjujejo določene zahteve v zvezi s kakovostjo, ki se
določijo na podlagi opredeljene velikosti serije z najmanjšim številom meritev.
6 Zahteve in izjava o skladnosti
V skladu s tem dokumentom morajo biti trdna alternativna goriva skladna z naslednjimi zahtevami:
a) trdna alternativna goriva morajo biti klasificirana v skladu s sistemom v točki 7;
b) trdna alternativna goriva morajo izpolnjevati zahteve za kakovost v skladu s pravili skladnosti,
podanimi v točki 8;
c) lastnosti trdnih alternativnih goriv se morajo določiti v skladu s točko 9.
Proizvajalec/dobavitelj trdnega alternativnega goriva mora predložiti izjavo o skladnosti k temu
dokumentu. Zapis mora biti na voljo za pregled. Vzorčna predloga za izjavo je podana v dodatku C.
OPOMBA: Splošna merila za izjavo dobavitelja so podana v standardih EN ISO/IEC 17050-1:2010 in EN ISO/IEC
17050-2:2004.
7 Klasifikacija
Sistem klasifikacije (preglednica 1) za trdna alternativna goriva temelji na mejnih vrednostih za tri
pomembne karakteristike goriva.
Te so:
a) povprečna vrednost za spodnjo kalorično vrednost (kp);
b) povprečna vrednost za vsebnost klora (s);
c) mediana in vrednost 80. percentila za vsebnost živega srebra (kp).
Vsaka karakteristika je razdeljena na 5 razredov. Trdnemu alternativnemu gorivu se dodeli številka
razreda od 1 do 5 za vsako karakteristiko. Kombinacija številk razreda sestavlja kodo razreda (glej
primer spodaj). Karakteristike so enako pomembne in tako nobena posamezna številka razreda ne
določa kode.
Koda razreda mora biti vključena v specifikacijo, kot je opisano v točki 9.
Zaradi vzorca statistične porazdelitve karakteristike morajo biti vrednosti predstavljene kot:
– spodnja kalorična vrednost (SKV) povprečje (aritmetično);
– vsebnost klora (Cl) povprečje (aritmetično);
– vsebnost živega srebra (Hg) mediana in 80. percentil.
8

---------------------- Page: 12 ----------------------

SIST EN 15359 : 2012
Višja izmed dveh statističnih vrednosti (mediana in 80. percentil) v podatkovnem nizu Hg določi
razred.
PRIMER: Trdno alternativno gorivo z mediano 0,03 in vrednostjo 80. percentila 0,07 spada v razred vsebnosti živega
srebra 3 (glede na preglednico 1).
Za določanje spodnje kalorične vrednosti se uporablja standard EN 15400, za določanje vsebnosti
klora standard EN 15408, za določanje vsebnosti živega srebra pa standard EN 15411.
OPOMBA 1: 80. percentil je vrednost, v katero ali pod katero pade 80 % opazovanj.
OPOMBA 2: Podrobnosti o statističnih podatkih najdete v CEN/TR 15508 [5].
OPOMBA 3: Povprečja in percentili so določeni na količini trdnega alternativnega goriva, kot je določeno v točki 8.
OPOMBA 4: Razredi so bili določeni kot orodje za identifikacijo in predhodni izbor trdnih alternativnih goriv. Vendar je
zmogljivost obrata, kjer se uporabljajo trdna alternativna goriva, odvisna od lastnosti trdnih alternativnih goriv in
še bolj od zasnove in delovnih pogojev obrata.
OPOMBA 5: Vse vrste trdnih alternativnih goriv niso primerne za vse vrste obratov (glej CEN/TR 15508) [5]. Na primer, če se
za gorivo uporablja 100 % trdnih alternativnih goriv, mejna vrednost emisij za vsebnost živega srebra pa je
3
določena pri 0,05 mg/m za cementne in apnene peči ter za elektrarne, je ustrezno gorivo iz razreda vsebnosti
živega srebra 1 za vse naštete vrste. Gorivo iz razreda vsebnosti živega srebra 5 se lahko v teh postopkih
uporablja samo, če gorivo iz tega razreda predstavlja manj kot 100 % mešanice goriva. Pri drugih razredih
poseben faktor prenosa danega procesa in delež trdnega alternativnega goriva določata, kateri razredi se lahko
uporabijo brez izboljšanja pogojev prenosa. Primeri faktorjev prenosa za obstoječe procese so podani v
CEN/TR 15508.
OPOMBA 6: Trdna alternativna goriva se ne smejo uporabljati kot goriva, če pri zgorevanju trdnih alternativnih goriv nastane
manj toplotne energije za delovanje obrata, kot se je porabi za zgorevanje trdnih alternativnih goriv (ki tako ni na
voljo za delovanje). To lahko na primer prepreči uporabo spodnje kalorične vrednosti razreda 5 v obratih, ki
zahtevajo višjo minimalno spodnjo kalorično vrednost za pridobivanje energije.

8.1 Pravila skladnosti za klasifikacijo
Pravila skladnosti za klasifikacijo so prikazana s primeri v dodatku D.
Za upoštevano 12-mesečno obdobje se za vsako karakteristiko, določeno v sistemu klasifikacije,
skladnost posameznega trdnega alternativnega goriva določi s prikazom, da so izmerjene lastnosti
skladne z mejnimi vrednostmi za ta razred. To se izvede v obdobju, v katerem se uporabi sistem
vodenja kakovosti. Največja teža serije za klasifikacijo ne sme biti večja od 1500 ton. Če je
proizvodnja v 12 mesecih manjša od 15 000 ton, je velikost serije za klasifikacijo ena desetina
količine, proizvedene v tekočem 12-mesečnem obdobju.
Če pride do znatnih sprememb lastnosti vhodnih materialov ali pogojev proizvodnega procesa, se
proizvodnja šteje za prekinjeno. Na tem mestu »znatne spremembe« pomenijo takšno spremembo, ki
povzroči spremembo kode razreda.
OPOMBA 1: Če klasifikacija ne more temeljiti na 12-mesečnem obdobju dejanske proizvodnje, je treba v tekoče obdobje
12 mesecev vključiti oceno načrtovane proizvodnje manjkajočega meseca.
OPOMBA 2: Sistem vodenja kakovosti je vsak sistematičen postopek, ki se uporablja za doseganje skladnosti s tem
evropskim standardom.
Za vsako serijo se izvede vsaj ena meritev vsake karakteristike. Če je potrebno navzkrižno
preverjanje, je treba vzeti dodaten laboratorijski vzorec. Laboratorijski vzorec je treba hraniti najmanj
12 mesecev. Vzorčenje in postopek vzorčenja sta prikazana na sliki 2. Za vzorčenje in zmanjševanje
vzorca se uporablja standard EN 15442.
Primerjava spodnje kalorične vrednosti in vsebnosti klora z mejnimi vrednostmi razredov se izvede z
upoštevanjem 95-odstotnega intervala zaupanja aritmetičnega povprečja desetih meritev. Za izračun
spodnje in zgornje meje 95-odstotnega intervala zaupanja aritmetičnega povprečja se uporabi
naslednja enačba:
1,96
s
X= X± ⋅

n
kjer so:
X spodnja/zgornja meja 95-odstotnega intervala zaupanja aritmetičnega povprečja
X aritmetično povprečje (na podlagi vseh meritev)

1,96 funkcionalna karakteristika normalne porazdelitve (za 95-odstotni interval zaupanja)
s standardni odmik (na podlagi vseh meritev)
n število meritev (tukaj n = 10)
Za kategorizacijo karakteristične spodnje kalorične vrednosti je odločilna izračunana spodnja meja
95-odstotnega intervala zaupanja aritmetičnega povprečja, za vsebnost klora pa ustrezna zgornja
meja.
Koda razreda za vsebnost živega srebra se določi glede na mediano in 80. percentil na podlagi
podatkovnega niza desetih zaporednih meritev.
Če po koncu 12-mesečnega obdobja obstaja nepopoln podatkovni niz (z manj kot 10 podatki), se ti
podatki uporabijo v naslednjem 12-mesečnem obdobju ter se dopolnijo z zaporednimi meritvami tega
obdobja, dokler ne nastane popoln podatkovni niz z 10 meritvami. V primeru, ko pri klasifikaciji ene
karakteristike več analiz v 12-mesečnem obdobju prinese različne rezultate klasifikacije, je treba za
določanje razreda trdnega alternativnega goriva vedno uporabiti najvišji razred (glej primer 2 v
točki D.2).

Introduction
The objective of this document is to provide unambiguous and clear classification and specification
principles for solid recovered fuels (SRF). The document aims at serving as a tool to enable efficient
trading of SRF, promoting their acceptability on the fuel market and increasing the public trust. The
document will facilitate a good understanding between seller and buyer, facilitate purchase,
transborder movements, use and supervision as well as a good communication with equipment
manufacturers. It will also facilitate authority permission procedures and ease the reporting on the use
of fuels from renewable energy sources and on other environmental issues.
)

SRF are produced from non hazardous waste. The input waste can be production specific waste,
municipal solid waste, industrial waste, commercial waste, construction and demolition waste, sewage
sludge etc. It is thus obvious that SRF are a heterogeneous group of fuels. A well defined system for
classification and specification is therefore of great importance to reach the above mentioned
objectives and intentions.
This document covers all types of SRF and will thus have a wide field of application. It supports the
objectives and implementation of the EU waste hierarchy as defined in article 3.1 of the waste
framework directive 2006/12/EC. [1]
This document describes the compliance rules which SRF has to meet to be classified according to
the classification system. It also describes how the supplier can establish a declaration of conformity to
the different EN standards for SRF.
Figure 1 illustrates a simplified flow chain for SRF, from input of waste to end use of SRF. This
document has an interface to all the stages in the chain, but SRF classification and specification are
applicable at the point of delivery as shown in the figure. Requirements for how the input waste is
collected and how to use the fuel are not part of this document.

Hazardous waste is defined in the Directive on hazardous waste (91/689/EEC) and its amendments, and are
elucidated and exemplified in the waste list ((Commission decision 2000/532) and its amendments, in particular
2001/118/EC).

5 Principles
The classification system is based on three important characteristics, referred to the main SRF
characteristics: an economic characteristic (net calorific value), a technical characteristic (chlorine
content) and an environmental characteristic (mercury content). The characteristics are chosen to give
a stakeholder an immediate but simplified picture of the fuel in question.
Only fuels derived from non hazardous waste that meet the SRF EN-standards can be classified as
SRF.
The classification itself is not enough for an intending user. A user has to have a more detailed
description of the fuel. Relevant fuel properties are thus to be further specified. Some of the fuel
properties are so important that they are obligatory to specify whereas others can be recorded
voluntarily, e.g. upon request of the user.
It is important that SRF meet specified quality requirements which are to be determined based on a
defined lot size by a minimum number of measurements.
6 Requirements and declaration of conformity
In conformity with this document, SRF shall comply with the following requirements:
a) SRF shall be classified according to the system in Clause 7;
b) SRF shall meet quality requirements according to given compliance rules in Clause 8;
c) SRF properties shall be specified according to Clause 9.
8

---------------------- Page: 10 ----------------------
oSIST prEN 15359:2009
prEN 15359:2009 (E)
The producer/supplier shall give a declaration of conformity to this document. The record shall be kept
available for inspection. A model template for the declaration is given in Annex C.
NOTE General criteria for a supplier’s declaration is given in EN ISO/IEC 17050-1:2004 and
EN ISO/IEC 17050-2:2004.
7 Classification
The classification system (Table 1) for SRF is based on limit values for three important fuel
characteristics. These are:
a) the mean value for net calorific value (ar);
b) the mean value for chlorine content (d);
th
c) the median and 80 percentile values for mercury content (ar).
Each characteristic is divided into 5 classes. The SRF shall be assigned a class number from 1 to 5 for
each characteristic. A combination of the class numbers makes up the class code (see example
below). The characteristics are of equal importance and thus no single class number determines the
code.
The class code shall be included in the specification as described in Clause 9.
Due to the statistical distribution pattern of the characteristics the values shall be presented as:
 net calorific value (NCV) mean (arithmetic);
 chlorine content (Cl) mean (arithmetic);
th
 mercury content (Hg) median and 80 percentile.
th
The higher of the two statistical values (median and 80 percentile) in a Hg data set determines the
class.
th
EXAMPLE A SRF with a median value of 0,03 and a 80 percentile value of 0,07 belongs to Hg class 3.
(according to Table 1).
For NCV, Cl and Hg the test methods in the corresponding EN-standards shall be used.
th
NOTE 1 80 percentile is the value on or below which 80 % of the observations fall.
NOTE 2 For details on statistics see CEN Report CEN/TR 15508 ”Key properties of solid recovered fuels to be
used for establishing a classification system”[6].
NOTE 3 The averages and percentiles are determined on the quantity of SRF as specified in Clause 8.
NOTE 4 The classes have been determined as a tool for identifying and pre-selecting SRF. However, the
performances of the plant where SRF is used are depending on the properties of the SRF and more significantly
on the design and operating conditions of such a plant.
NOTE 5 Not all kinds of SRF are suited for all types of installation (see CEN/TR 15508, Brussels, Belgium,
3
2006)[6]. For example, if 100 % SRF is used as fuel and an emission limit for Hg is defined at 0.05 mg/m , for
cement and lime kilns as well as for power plants, Class Hg 1 fuels would fit to all types of these. Class Hg 5 fuels
could only be used in these processes if this class of fuel is less than 100 % of the fuel mix. For other classes the
specific transfer factor of a given process and the proportion of SRF will determine which classes can be used
without improvement of the transfer conditions. Examples of transfer factors for existing processes are given in
CEN/TR 15508.

NOTE 6 SRF should not be used as a fuel if there is less thermal energy produced from the combustion of the
SRF and available for the process of the installation, than the energy used by the combustion of the SRF (thus
not available for the process). This can, for example, prevent the use of class NCV 5 in installations requiring a
higher minimum NCV for energy recovery.

0,05 mg/MJ (ar) is designated as:
Class code NCV 3; Cl 2; Hg 2.
8 Compliance rules
8.1 Compliance rules for classification
The compliance rules for classification are illustrated by examples in Annex D.
For a considered 12 months period, for each characteristic specified in the classification system, the
compliance of a particular SRF shall be established by demonstration that the measured properties
conform to the limit values defined for that class. This shall be performed at a period in which a quality
management system (QMS) is applied. The maximum weight of a lot for classification shall be no
more than 1 500 tonnes. When the 12 month production is less than 15 000 tonnes the lot size for
classification shall be one tenth of the amount produced in a 12 months rolling period.
NOTE 1 If the classification cannot be based on a 12 month period of actual production, an estimation of the
planned production of the missing month should be included in the rolling 12 month period.
NOTE 2 If there are significant changes in the properties of input materials or in the production process
conditions, the production shall be considered to be interrupted. Significant means such a change that would
result in a change of class code.
NOTE 3 A quality management system is meant as any systematic procedure used for complying with this
standard.

---------------------- Page: 12 ----------------------
oSIST prEN 15359:2009
prEN 15359:2009 (E)
For each lot, at least one measurement of each characteristic shall be performed. An additional
laboratory sample shall be taken in case of a cross check is needed. It shall be kept until the
measurement has been validated. The sampling and sample procedure are illustrated in Figure 2. For
sampling and sample reduction prEN 15442 shall be applied.
The comparison for NCV and Cl with the limit values of the classes is made by taking the 95 %
confidence interval of the arithmetic mean of 10 measurements into account. For the calculation of the
lower and the upper limit of the 95 % confidence interval of the arithmetic mean the following formula
shall be used:
s
X = X ±1,96⋅
n
X lower/upper limit of the 95 % confidence interval of the arithmetic mean;
X arithmetic mean (based on all measurements);
1,96 functional characteristic of the normal distribution (for the 95 % confidence interval);
s standard deviation (based on all measurements);
n number of measurements (here n=10).
Decisive for the categorisation of the characteristic NCV is the calculated lower limit of the 95 %
confidence interval of the arithmetic mean and for Cl the corresponding upper limit.
th
The class code for Hg is established using median and 80 percentile based on data sets of 10
consecutive measurements. If, at the end of the 12 month period, an incomplete data set exists (with
less than 10 data), these data shall be used in the following 12 month period and be completed with
the consecutive measurements of that period to a full data set of 10 measurements. In the case that
for one characteristic to be classified several analyses of a 12 month period lead to different
classification results, always the highest class has to be used for the determination of the class of the
SRF.
After the start of the production of SRF or after a significant change, the minimum of 10 measurement
results can be obtained on one or several lots as defined above. When several combined samples are
taken on the same lot they shall be taken independently.
For process control reasons it is recommended to calculate the median and the 80 percentile value
after the measurement of every lot (e.g. for data sets No. 1 to No. 10 / No. 2 to No. 11 / etc.) and to
consider the short time variation of the analytical results.
Within the characterisation period it is recommended to use as a prediction method for virgin
producers the 50 % - rule for Hg classification. This prediction method is working according to the
principle of a conservative classification (indirect safety margin).
NOTE 4 If production time is less than 12 months it can be considered and treated as an initial phase of the
production.
NOTE 5 The 50 % rule means that classification is determined by comparing the measurement results to 50 %
of the class limits (median and/or 80-percentile). For more details see CEN/TR 15508 “Key properties of solid
recovered fuels to be used for establishing a classification system“ [6].
8.2 Compliance rules for specification
The SRF specification to be agreed upon by the supplier and the user may define the lot size up to a
maximum of 1500 tonnes as well as by the compliance rules. In case these elements are not defined
in the SRF specification, then the lot size and compliance rules specified for the classification apply.

Particle form of the SRF shall be specified. Examples of forms are pellets, bales,
briquettes, chips, flakes, fluff and powder. Other forms may be used and
shall then be specified separately.
Particle size in the fuel shall be specified by sieving or equivalent techniques, and be
expressed as dx, where d is the particle size on the distribution curve
where x % passes according to prEN 15415, Solid recovered fuels -
Determination of particle dimensions and particle size distribution.
Ash content shall be specified on dry bases according to prEN 15403, Solid recovered
fuels - Methods for the determination of ash content.
Moisture content shall be specified as received according to prEN 15414, Parts 1, 2 and 3,
Solid recovered fuels — Methods for the determination of moisture content.
Net calorific value  shall be specified both as received and on dry bases according to
prEN 15400, Solid recovered fuels — Methods for the determination of
calorific values.
Chemical properties - the chlorine content shall be specified based on dry basis according to
prEN 15408.
- the content of each heavy metal separately as well as the sum thereof as
mentioned in Waste Incineration Directive [3] shall be specified on dry
basis according to prEN 15411. The heavy metals are antimony, arsenic,
cadmium, chromium, cobalt, copper, lead, manganese, mercury, nickel,
thallium and vanadium. Cadmium, mercury and thallium are not included in
the sum.
9.3 Properties non-obligatory to specify
The properties in Annex A, Part 2 are voluntary to specify. These properties are:
Biomass content of the SRF should be specified and shall then be measured according to
prEN 15440, Solid recovered fuels - Methods for the determination of the
biomass content. [12] The fraction of biomass can be expressed by weight,
by energy content or by carbon content. The biomass content in percent by
carbon content is necessary in order to calculate the emission of biomass
or fossil carbon dioxide per unit SRF.
NOTE 1 More information on biomass content is available in CEN/TR 14980. [7]
NOTE 2 More information on the emission factor and how to calculate it is
available in Commission Decision 2007/589/EC establishing guidelines for the
monitoring and reporting of greenhouse gas emissions pursuant to Directive
2003/87/EC of the European Parliament and of council of 18 July 2007 [14].
Composition is the weight percentage of main fractions of wood, paper, plastics, rubber,
textiles etc. The basis (dry or wet) should be specified.
