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 volatile matter is determined as the loss in mass of the analysed sample, after moisture removal,

when material is heated up under specific conditions of temperature, time and in a reduced atmosphere

(anoxic conditions). The test is empirical and, in order to ensure reproducible results, it is essential that

the rate of heating, the final temperature and the overall duration of the test are carefully controlled. It

is also essential to exclude air from the solid recovered fuel during heating to prevent oxidation.

The moisture content of the sample is determined at the same time as the volatile matter so that the

appropriate correction can be made. Mineral matter associated with the sample can also lose mass

under the conditions of the test, the magnitude of the loss being dependent on both the nature and the

quantity of the minerals present.

This document is primarily geared toward laboratories, producers, suppliers and purchasers of solid

recovered fuels, but is also useful for the authorities and inspection organizations.

3 Terms and definitions

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

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

3.1
ash
ash content on dry basis
total ash

mass of inorganic residue remaining after combustion of a fuel under specified conditions, typically

expressed as a percentage of the mass of dry matter in fuel

Note 1 to entry: Depending on the combustion efficiency the ash may contain combustibles.

Note 2 to entry: If a complete combustion is realized, ash contains only inorganic, non-combustible components.

renumbered, and symbol "A" was italicized.]

3.2
removed ash contributor
rac

coarse inert material (i.e. metals, glass, stones, tiles etc.) removed from the pre-dried sample before

preparation, in order to avoid damage to the preparation equipment

Note 1 to entry: Removed ash contributors are included in the ash content calculations.

[SOURCE: ISO 21637:2020, 3.62, modified – Note 1 to entry was added.]
3.3
total organic matter

combustible part of solid recovered fuels, which consists of the sum of volatile matter and fixed carbon

Note 1 to entry: It is calculated as: 100 - moisture content - ash content.

Note 2 to entry: It is the mass fraction of the matter lost by ignition, also known as “Loss Of Ignition” (LOI).

3.4
volatile matter

relative part of the analysed sample, after moisture removal, that is lost when material is heated up

under specific conditions of temperature, time and in a reduced atmosphere (anoxic conditions)

3.5
fixed carbon

relative part of carbon contained in a material that can only be degraded in oxic conditions and high

temperature

Note 1 to entry: It is calculated as: 100 - moisture content - volatile matter content - ash content.

3.6
pre-drying

drying process to minimise moisture loss in the subsequent sample-division processes, to facilitate the

sample preparation processes, and to minimise biological activity
4 Principle

A test portion of the general analysis sample is heated out of contact with ambient air at (900 ± 10) °C

for 7 min. The percentage of volatile matter is calculated from the loss in mass of the test portion after

deducting the loss in mass due to moisture. The test is empirical and, in order to ensure reproducible

results, it is essential that the rate of heating, the final temperature and the overall duration of the test

are carefully controlled.

Automatic equipment (such as thermogravimetric analysers) may be used as long as the equipment is

validated by parallel measurements to the reference method. The automatic equipment shall fulfil all

the requirements regarding sample size, heating procedure, temperature, atmosphere and weighing

accuracy. Deviations from this paragraph shall be reported and justified.
5 Apparatus
5.1 Furnace

The furnace shall be heated electrically and capable of maintaining a temperature of (900 ± 10) °C. It

may be of the stop-ended type or fitted at the back with a flue with
