Solid biofuels - Determination of moisture content - Part 1: Reference method (ISO 18134-1:2022)

This document describes the method of determining the moisture content of a test sample of solid
biofuels by drying in an oven and can be used when high precision of the determination of moisture
content is necessary. The method described in this document 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).
NOTE Biomass materials can contain small amounts of volatile organic compounds (VOC) which can
evaporate when determining moisture content by oven drying (see References [1] and [2]). The release of
such compounds is quite small relative to the overall moisture content as determined by this method and is
disregarded in this document

Biogene Festbrennstoffe - Bestimmung des Wassergehaltes - Teil 1: Referenzverfahren (ISO 18134-1:2022)

Dieses Dokument legt das Verfahren zur Bestimmung des Wassergehaltes einer Versuchsprobe von biogenen Festbrennstoffen durch Trocknen in einem Ofen fest und kann angewendet werden, wenn eine hohe Präzision der Bestimmung des Wassergehaltes erforderlich ist. Das in diesem Dokument festgelegte Verfahren ist für alle biogenen Festbrennstoffe anwendbar. Der Wassergehalt von biogenen Festbrennstoffen (im Anlieferungszustand) wird immer bezogen auf die Gesamtmasse der Versuchsprobe (Bezugsbasis Feuchtmasse) angegeben.
ANMERKUNG   Biomasse-Materialien 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 - Méthode de séchage à l'étuve - Partie 1: Méthode de référence (ISO 18134-1:2022)

Le présent document décrit la méthode de dosage de la teneur en humidité d’un échantillon pour essai de biocombustibles solides par séchage à l’étuve. Cette méthode peut être utilisée lorsqu’une grande fidélité est nécessaire. La méthode décrite dans le présent document 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).
NOTE            Les matériaux de la biomasse peuvent contenir de petites quantités de composés organiques volatils (COV) qui peuvent s'évaporer lors du dosage de la teneur en humidité par séchage au four (voir Références [1] et [2]). La libération de ces composés est très faible par rapport à la teneur en humidité globale telle que déterminée par cette méthode et n'est pas prise en compte dans le présent document.
