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
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

Introduction
The objective of this document is to provide a common classification and specification system for solid
recovered fuels (SRF) to enable efficient trading of SRF, to promote their safe use in energy conversion
activities and to increase the public trust. The document facilitates a good understanding between
seller and buyer, supports purchase, trans border movements, use and supervision as well as an
effective communication with equipment manufacturers. The classification and specification system
support authority permission procedures and ease the reporting on 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 significant 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 aim of producing
a solid recovered fuel is to use it for energy purposes at th
