Solid biofuels - Determination of moisture content - Part 3: Moisture in general analysis sample (ISO 18134-3:2023)
This document describes the method of determining the moisture content in the general analysis sample by drying in an oven. 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).
Since biofuels in small particle size are very hygroscopic, their moisture content will change with humidity in the atmosphere and, therefore, the moisture of the general analysis sample is determined simultaneously with the determination of other properties being measured (e.g. calorific value, volatile matter, metals, etc.).
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 3: Wassergehalt in allgemeinen Analysenproben (ISO 18134-3:2023)
Dieses Dokument beschreibt das Verfahren zur Bestimmung des Wassergehaltes in der allgemeinen Analysenprobe durch Trocknung in einem Ofen. Das in diesem Dokument beschriebene 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.
Da biogene Brennstoffe mit kleiner Partikelgröße stark hygroskopisch sind, ändert sich deren Wassergehalt bei Änderung der Luftfeuchte, und deshalb wird der Wassergehalt der allgemeinen Analysenprobe gleichzeitig mit der Bestimmung anderer zu messender Eigenschaften (z. B. Energiegehalt, flüchtige Bestandteile, Metalle usw.) ermittelt.
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 - Partie 3: Humidité de l'échantillon pour analyse générale (ISO 18134-3:2023)
Le présent document décrit la méthode de dosage de la teneur en humidité de l'échantillon pour analyse par séchage à l'étuve. 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).
Les biocombustibles constitués de particules de petite taille étant très hygroscopiques, leur teneur en humidité varie en fonction de l'humidité de l'atmosphère et, par conséquent, l'humidité de l’échantillon pour analyse générale est établie simultanément avec la détermination d’autres propriétés mesurées (par exemple, le pouvoir calorifique, la matière volatile, les métaux, etc.).
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 à l’étuve (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.
Trdna biogoriva - Določevanje vlage - 3. del: Vlaga v splošnem analiznem vzorcu (ISO 18134-3:2023)
Standard ISO 18134-3:2015 opisuje metodo določevanja vlage v analiznem vzorcu s sušenjem vzorca v peči. Uporablja se za splošne analizne vzorce v skladu s standardom EN 14780. Metoda, opisana v tem delu standarda ISO 18134-3:2015, se uporablja za vsa trdna biogoriva. Navedena vsebnost vlage v trdnih biogorivih (pri dobavi) vedno temelji na skupni masi preskusnega vzorca (mokra osnova).
Ker so biogoriva v majhnih zrnih zelo higroskopska, se vsebnost vlage v njih spreminja glede na vlažnost v okolju. Zaradi tega je treba vlažnost uporabljenega dela vzorca določiti sočasno z npr. kalorično vrednostjo, vsebnostjo ogljika in dušika.
OPOMBA: Izraz »vsebnost vlage« je lahko pri uporabi v zvezi z materiali iz biomase zavajajoč, saj neobdelana biomasa pogosto vsebuje različne količine hlapnih snovi (ekstraktov), ki lahko pri določevanju vsebnosti vlage s sušenjem vzorca v peči izhlapijo (glej vira [1] in [2]).

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 document 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).
