Solid recovered fuels - Terminology, definitions and descriptions
This European Standard defines terms and definitions concerned in all standardisation work within the scope of CEN/TC 343, i.e. terms used in the field of production and trade of solid recovered fuels that are prepared from non-hazardous waste.
NOTE Solid biofuels are covered by the scope of CEN/TC 335.
The embedding of the scope within the waste/solid recovered fuels field is given in Figure 1.
Definitions in other standards with a scope different from the scope of this European Standard can be different from the definitions in this European Standard.

EN 15357:2011 (E) 6 Introduction The drafting of this European Standard, that aims to provide a comprehensive solid recovered fuel glossary, has been performed in accordance with ISO 10241:1992 [1]. Terms are arranged in alphabetic order. Attention is drawn to the fact that the terms: biomass, biodegradable, co-incineration plant, emission, incineration plant, renewable energy source, waste, waste supplier listed in this European Standard are defined, amongst others, also in the following Directives, Decisions (see Bibliography): Council Directive 1999/31/EC of 26 April 1999 on the landfill of waste [3]; Directive 2001/77/EC of the European Parliament and of the Council of 27 September 2001 on the promotion of electricity produced from renewable energy sources in the internal electricity market [4]; Directive 2000/76/EC of the European Parliament and of the Council of 4 December 2000 on the incineration of waste [5]; Directive 2008/98/EC of the European Parliament and of the Council of 19 November 2008 on waste and repealing certain directives [6]; Commission Decision (2007/589/EC) of 18 July 2007 establishing guidelines for the monitoring and reporting of greenhouse gas emissions [16]. NOTE Legislation can change. DG XI Director General communicated to CEN in 1996 that "when a definition exists in a Directive, it not only applies strictly for the purposes of the Directive, but also to all adjacent work such as that of CEN. No other definition can be used if not agreed by the Council". As a consequence, definitions given in European Standards, Technical Specifications or Technical Reports cannot contradict definitions contained in European Legislation. Many terms defined by EN ISO 9000 are used in the standardisation work within the scope of CEN/TC 343, especially in EN 15358 [17]. Therefore an informative list of terms defined by EN ISO 9000 is given in Annex A. SIST EN 15357:2011

Introduction
The drafting of this European Standard, that aims to provide a comprehensive solid recovered fuel glossary,
has been performed in accordance with ISO 10241:1992 [1]
Terms are arranged in alphabetic order.
Attention is drawn to the fact that the terms:
biomass, biodegradable, co-incineration plant, emission, incineration plant, renewable energy source,
waste, waste supplier
listed in this European Standard are defined, amongst others, also in the following Directives, Decisions (see
Bibliography):
Council Directive 1999/31/EC of 26 April 1999 on the landfill of waste [3]
Directive 2001/77/EC of the European Parliament and of the Council of 27 September 2001 on the
promotion of electricity produced from renewable energy sources in the internal electricity market [4]
Directive 2000/76/EC of the European Parliament and of the Council of 4 December 2000 on the
incineration of waste [5]
Council Directive 75/442/EEC of 15 July 1975 on waste and its following amendments [6]
Commission Decision (2007/589/EC) of 18 July 2007 establishing guidelines for the monitoring and
reporting of greenhouse gas emissions [16]
NOTE: Legislation may change
DG XI Director General communicated to CEN in 1996 that "when a definition exists in a Directive, it not only
applies strictly for the purposes of the Directive, but also to all adjacent work such as that of CEN. No other
definition can be used if not agreed by the Council"
As a consequence, definitions given in European Standards, Technical Specifications or CEN reports cannot
contradict definitions contained in European Legislation.
Many terms defined by ISO 9000 are used in the standardisation work within the scope of CEN/TC 343,
especially in the CEN/TS 15358 Solid recovered fuels – Quality management systems – Particular
requirements for their application to the production of solid recovered fuels .
Therefore an informative list of terms defined by ISO 9000 is given in Annex A.

1. Scope
This European Standard defines terms concerned in all standardisation work within the scope of CEN/TC 343,
i.e. terms used in the field of production and trade of solid recovered fuels that are prepared from non-
hazardous waste.
NOTE Solid biofuels are covered by the scope of CEN/TC 335.
The embedding of the scope within the waste/solid recovered fuels field is given in Figure 1.

Definitions in other standards with a scope different from the scope of this European Technical Specification
can be different from the definitions in this technical specification.

3. Terms and definitions
3.1
as received, as received basis
calculation basis for material at delivery
3.2
ash deformation temperature
temperature at which first signs of rounding due to melting, of the tip or edges of the test piece occur
NOTE: Adapted from ISO 540:1995 [2]
3.3
ash flow temperature
temperature at which the ash is spread out over the supporting tile in a layer, the height of which is one-third
of the height of the test piece at the ash hemisphere temperature
NOTE: Adapted from ISO 540:1995
3.4
ash fusibility ; ash melting behaviour
characteristic physical state of the ash obtained by heating under specific conditions
NOTE 1 Ash fusibility is determined under either oxidizing or reducing conditions.
NOTE 2 See also ash deformation temperature, ash flow temperature, ash hemisphere temperature, and ash
sphere temperature
NOTE 3 Adapted from ISO 540:1995
3.5
ash hemisphere temperature
temperature at which the height of a test piece, prepared from ash by a specific procedure, is equal to half the
width of the base, and its shape becomes approximately hemispherical
NOTE: Adapted from ISO 540:1995
3.6
ash sphere temperature
temperature where the height of a pyramidal and truncated-cone test pieces is equal to the width of the base,
or the edges of a cubical or cylindrical test pieces are completely round with the height remaining unchanged
NOTE: Adapted from ISO 540:1995

1)
biodegradable
3.8
biogenic
produced by living organisms in natural processes but not fossilised or derived from fossil resources
NOTE 1 The term biogenic is used to denote CO -neutral material when degraded under aerobic conditions (e.g.

combustion, incineration)
