Solid biofuels - Fuel specifications and classes - Part 6: Graded non-woody pellets (ISO 17225-6:2014)
EN ISO 17225-6 determines the fuel quality classes and specifications of graded non-woody pellets. This part of ISO 17225 covers only non-woody pellets produced from the following raw material (see ISO 17225-1, Table 1): - 2 Herbaceous biomass - 3 Fruit biomass - 4 Aquatic biomass - 5 Biomass blends and mixtures. Blends are intentionally mixed biofuels, whereas mixtures are unintentionally mixed biofuels. The origin of the blend and mixture is to be described using ISO 17225-1, Table 1. If solid biofuel blend or mixture contains chemically treated material it shall be stated.
Feste Biobrennstoffe - Brennstoffspezifikationen und - klassen - Teil 6: Einteilung von nicht-holzartigen Pellets (ISO 17225-6:2014)
Dieser Teil der ISO 17225 legt die qualitätsbezogenen Brennstoffklassen und spezifikationen für klassifizierte nicht-holzartige Pellets fest. Dieser Teil der ISO 17225 umfasst nur nicht-holzartige Pellets, die aus folgenden Rohmaterialien hergestellt wurden (siehe ISO 17225-1, Tabelle 1):
- 2 halmgutartige Biomasse;
ANMERKUNG 1 Halmgutartige Biomasse stammt von Pflanzen mit einem nicht verholtztem Stängel, die am Ende der Wachstumssaison absterben. Dazu gehören Getreide oder Saatgutpflanzen aus der Lebensmittel herstellenden oder verarbeitenden Industrie und deren Nebenprodukte, wie z. B. Getreide.
- 3 Biomasse von Früchten;
- 4 aquatische Biomasse;
- 5 definierte und undefinierte Mischungen von Biomasse.
ANMERKUNG 2 Gruppe 5 Definierte und undefinierte Mischungen umfasst definierte und undefinierte Mischungen aus den auf der Herkunft beruhenden Hauptgruppen fester Biogene Brennstoffe holzartige Biomasse, halmgutartige Biomasse, Biomasse von Früchten und aquatische Biomasse.
Definierte Mischungen sind absichtlich gemischte biogene Brennstoffe, während undefinierte Mischungen zufällig gemischte biogene Brennstoffe sind. Die Herkunft der definierten und undefinierten Mischungen ist unter Anwendung von ISO 17225-1, Tabelle 1, zu beschreiben.
Wenn eine definierte oder undefinierte Mischung von festen biogenen Brennstoffen chemisch behandeltes Material enthält, muss dies angegeben werden.
ANMERKUNG 3 Thermisch behandelte Biomassepellets (z. B. torrefizierte Pellets) fallen nicht in den Anwendungs-bereich dieses Teils der ISO 17225. Torrefizierung ist eine milde Vorbehandlung von Biomasse bei einer Temperatur zwischen 200 °C und 300 °C.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of

Introduction
The objective of the ISO 17225 series is to provide unambiguous and clear classification principles for
solid biofuels and to serve as a tool to enable efficient trading of biofuels and to enable good understanding
between seller and buyer as well as a tool for communication with equipment manufacturers. It will also
facilitate authority permission procedures and reporting.
This part of ISO 17225 supports the use of graded non-woody pellets for residential, small commercial
and public buildings as well as industrial energy generation applications, which require classified pellet
quality.
The residential, small commercial and public building applications require higher quality fuel for the
following reasons:
• Small-scale equipment does not usually have advanced controls and flue gas cleaning
• Appliances are not generally managed by professional heating engineers
• Appliances are often located in residential and populated districts
Non-woody pellets have high ash, chlorine, nitrogen and sulfur content and major element contents, so
non-woody pellets are recommended to be used in appliances, which are specially designed or adjusted
for this kind of pellet.
NOTE 1 Pellets produced according to this part of ISO 17225 may be used in pellet burners tested according to
[1] [2]
EN 15270 and pellet boilers or integrated-pellet burner systems tested according to EN 303–5 .
NOTE 2 When using non-woody materials for combustion special attention should be paid to the risk of
corrosion in small and medium scale boilers and flue gas systems. Be aware that herbaceous or fruit biomass may
influence the fuel ash composition differently depending on growth and soil conditions. The content of chlorine,
phosphate and potassium in the material may form chlorides and phosphates and other chemical compounds
resulting in high hydrochloric emissions and chemically active ash with low melting temperature causing
corrosion.
NOTE 3 In general non-woody biomass materials have higher content of ash forming elements and produces
ashes with lower melting temperature compared to most woody biomass. This may result in fouling, slagging
and corrosion inside boilers. These problems are especially related to materials that contain high content of
potassium (K) and silicate (Si) and low content of calcium (Ca).
NOTE 4 For individual contracts ISO 17225-1 can be used.
Although these product standards may be obtained separately, they require a general understanding of
the standards based on and supporting ISO 17225-1. It is recommended to obtain and use ISO 17225-1
in conjunction with these standards

INTERNATIONAL STANDARD ISO 17225-6:2014(E)
Solid biofuels — Fuel specifications and classes —
Part 6:
Graded non-woody pellets
1 Scope
This part of ISO 17225 determines the fuel quality classes and specifications of graded non-woody
pellets. This part of ISO 17225 covers only non-woody pellets produced from the following raw material
(see ISO 17225-1, Table 1):
– 2 Herbaceous biomass
NOTE 1 Herbaceous biomass is from plants that have a non-woody stem and which die back at the end of the
growing season. It includes grains or seeds crops from food production or processing industry and their by-
products such as cereals.
– 3 Fruit biomass
– 4 Aquatic biomass
– 5 Biomass blends and mixtures
NOTE 2 Group 5 Blends and mixtures include blends and mixtures from the main origin-based solid biofuel
groups woody, herbaceous biomass, fruit biomass and aquatic biomass.
Blends are intentionally mixed biofuels, whereas mixtures are unintentionally mixed biofuels. The
origin of the blend and mixture is to be described using ISO 17225-1, Table 1.
If solid biofuel blend or mixture contains chemically treated material it shall be stated.
NOTE 3 Thermally treated biomass pellets (e.g. torrefied pellets) are not included in the scope of this part of
ISO 17225. Torrefaction is a mild pre-treatment of biomass at a temperature between 200 °C to 300 °C.
