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.
Combustibles solides de récupération - Détermination de l'humidité par la méthode de séchage à l'étuve - Partie 3: Humidité de l'échantillon pour analyse générale (ISO 21660-3:2021)
Le présent document spécifie une méthode de détermination de l'humidité d'un échantillon pour analyse générale en le séchant dans une étuve. Cette méthode convient à une utilisation pour des échantillons d'analyse généraux conformément à la norme CEN/TS 15414-1[3][1]. Elle s'applique à tous les combustibles solides de récupération.
Si les combustibles solides de récupération contiennent de grandes quantités de fractions d'huile, la méthode Karl-Fischer (par exemple ISO 760) est recommandée. Sinon, une température plus faible est recommandée (par exemple 50 °C ± 10 °C), ainsi qu'une durée de séchage plus importante jusqu'à l'obtention d'une masse constante.
NOTE Le terme «teneur en humidité», lorsqu'il est utilisé avec «matériaux de récupération», peut induire en erreur puisque des matériaux solides de récupération, par exemple de la biomasse, contiennent fréquemment diverses quantités de composés volatils (extractibles) qui peuvent s'évaporer lors de la détermination de la teneur en humidité de l'échantillon pour analyses générales par séchage en étuve.
[1] L'adoption de la série de normes EN 15414 en tant que série de normes ISO 21660 est prévue. L'ISO 21660‑3 est publié en parallèle au niveau CEN en tant qu`EN 21660-3.
