Solid recovered fuels - Determination of moisture content using the oven dry method - Part 3: Moisture in general analysis sample (ISO 21660-3:2021)

This International Standard specifies a method for the determination of moisture in an analysis sample
by drying the sample in an oven. It is applicable to all solid recovered fuels.

Feste Sekundärbrennstoffe - Bestimmung des Wassergehaltes unter Verwendung des Verfahrens der Ofentrocknung - Teil 3: Wassergehalt in gewöhnlichen Analysenproben (ISO 21660-3:2021)

Dieses Dokument legt ein Verfahren zur Bestimmung des Wassergehaltes in einer allgemeinen Analysenprobe durch Trocknen der Probe in einem Ofen fest. Das Verfahren ist für die Anwendung bei allgemeinen Analysenproben nach CEN/TS 15414 1 [3]  geeignet. Es gilt für alle festen Sekundärbrennstoffe.
Wenn feste Sekundärbrennstoffe große Mengen an Ölfraktionen enthalten, ist das Karl-Fischer-Verfahren (z. B. ISO 760) empfehlenswert. Andernfalls werden eine niedrigere Temperatur (z. B. 50 °C ± 10 °C) und eine längere Trocknungszeit empfohlen, bis eine konstante Masse erreicht ist.
ANMERKUNG Der Begriff Wassergehalt kann bei der Anwendung im Zusammenhang mit Sekundärrohstoffen irreführend sein, weil Sekundärrohstoffe, z. B. Biomasse, oft unterschiedliche Mengen an flüchtigen Verbindungen (Extraktstoffen) enthalten, die bei der Bestimmung des Wassergehaltes einer allgemeinen Analysenprobe durch Ofentrocknung verdampfen können.

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).

Solid recovered fuels — Determination of moisture content
using the oven dry method —
Part 3:
Moisture in general analysis sample
1 Scope

This document specifies a method for the determination of moisture in a general analysis sample by

drying the sample in an oven. This method is suitable for use for general analysis samples in accordance

[3]1)
with CEN/TS 15414-1 . It is applicable to all solid recovered fuels.

If solid recovered fuels contain large amounts of oil-fractions the Karl-Fischer-Method (for example

ISO 760) is advisable. Otherwise, a lower temperature is recommended (e.g. 50 °C ± 10 °C) and a longer

drying time until constant mass is achieved.

NOTE The term moisture content, when used with recovered materials, can be misleading since solid

recovered materials, e. g. biomass, frequently contain varying amounts of volatile compounds (extractives)

which can evaporate when determining the moisture content of the general analyses sample by oven dr
