Solid recovered fuels - Methods for the determination of carbon (C), hydrogen (H), nitrogen (N) and sulphur (S) by the instrumental method (ISO 21663:2020)

This International Standard specifies a method for the determination of carbon (C), hydrogen (H),
nitrogen (N) and sulphur (S) by instrumental method. Depending on the amount of test portion used,
micro and macro instrumental apparatus are used.
An alternative method based on high temperature furnace combustion and IR detection is described in
Annex A.

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).

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.

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 %.

constitutes requirements of this document. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any amendments) applies.

For the purposes of this document, the terms and definitions given in ISO 21637 and the following apply.

coefficient of variation

estimate of the standard deviation of a population from a sample (3.10) of n results divided by the mean

of that sample
Note 1 to entry: Frequently stated as a percentage.
Note 2 to entry: Adapted from Eurachem/Citac Guide CG 4.

3.3
dry matter

[SOURCE: ISO 21637, 3.22]
3.4
general analysis sample

sub-sample of a laboratory sample having a nominal top size (3.7) of 1 mm or less and used for a number

of chemical and physical analyses
3.5
laboratory sample

combined sample received by the laboratory on which sample preparation procedures are undertaken

Note 1 to entry: When the laboratory sample is further prepared (reduced) by subdividing, mixing, grinding,

or by combinations of these operations, leading to a nominal top size ≤ 1mm, the result is the general analysis

sample. A test portion is removed from the general analysis sample for the performance of the test or for analysis.

When no preparation of the laboratory sample is required, the laboratory sample may become the test portion.

Note 2 to entry: 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 to entry: Several laboratory samples are 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.

moisture
water removable under specific conditions

nominal top size

smallest aperture size of the sieve used for determining the particle size distribution of solid recovered

fuels through which at least 95 % by mass of the total material passes through the sieve

3.8
particle size
size of the fuel particles as determined in a solid fuel
