Solid biofuels - Determination of moisture content - Part 2: Total moisture - Simplified method (ISO/DIS 18134‑2:2023)

ISO 18134-2:2017 describes the method of determining the total moisture content of a test sample of solid biofuels by drying in an oven and is used when the highest precision is not needed, e.g. for routine production control on site. The method described in ISO 18134 (all parts) is applicable to all solid biofuels. The moisture content of solid biofuels (as received) is always reported based on the total mass of the test sample (wet basis).

Biogene Festbrennstoffe - Bestimmung des Wassergehaltes - Teil 2: Gesamtgehalt an Wasser - Vereinfachtes Verfahren (ISO/DIS 18134‑2:2023)

Dieses Dokument beschreibt das Verfahren zur Bestimmung des Gesamtgehalts an Wasser einer Versuchsprobe von biogenen Festbrennstoffen durch Trocknen in einem Ofen und wird angewendet, wenn nicht die höchste Präzision erforderlich ist, z. B. zur routinemäßigen Produktionskontrolle im Betrieb. Das in ISO 18134 (alle Teile) beschriebene Verfahren ist auf alle biogenen Festbrennstoffe anwendbar. Der Wassergehalt von biogenen Festbrennstoffen (im Anlieferungszustand) wird immer bezogen auf die Gesamtmasse der Versuchsprobe (Bezugsbasis Feuchtmasse) angegeben.
ANMERKUNG   Biomassematerialien können geringe Mengen an flüchtigen organischen Verbindungen (VOC, en: volatile organic compounds) enthalten, die bei der Bestimmung des Wassergehaltes durch Ofentrocknung verdampfen können (siehe Literaturhinweise [1] und [2]). Die Freisetzung derartiger Verbindungen ist im Verhältnis zum Gesamtgehalt an Wasser, der mit diesem Verfahren bestimmt wird, verhältnismäßig gering und wird in diesem Dokument vernachlässigt.

Biocombustibles solides - Dosage de la teneur en humidité - Partie 2: Humidité totale - Méthode simplifiée (ISO/DIS 18134‑2:2023)

ISO 18134-2:2017 décrit la méthode de détermination de la teneur en humidité totale d'un échantillon pour essai de biocombustibles solides par séchage à l'étuve. Cette méthode est utilisée lorsque la fidélité maximale n'est pas nécessaire, par exemple, pour un contrôle de routine de la production in situ. La méthode décrite dans l'ISO 18134 (toutes les parties) est applicable à l'ensemble des biocombustibles solides. La teneur en humidité des biocombustibles solides (à réception) est toujours rapportée à la masse totale de l'échantillon pour essai (base humide).

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
