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
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).

ISO 21663:2020(E)
Introduction
The determination of total content of carbon, hydrogen, nitrogen and sulfur is usually performed
using instrumental methods. Depending on the amount of test portion used two different types of
instrumental methods can be used: micro methods require few milligrams of sample; macro methods
use grams of sample. Micro methods require a very careful preparation of the test sample for Solid
Recovered Fuel (SRF) analysis.
INTERNATIONAL STANDARD ISO 21663:2020(E)
Solid recovered fuels — Methods for the determination of
carbon (C), hydrogen (H), nitrogen (N) and sulphur (S) by
the instrumental method
1 Scope
This document specifies the determination of total content of carbon, hydrogen, nitrogen and sulfur
in solid recovered fuels by instrumental method. Depending on the amount of test portion, micro or
macro instrumental apparatus are used.
This method is applicable for concentrations on dry matter basis of C > 0,1 %, N > 0,1 %, H > 0,1 % and
S > 0,05 %.
