Solid biofuels - Sample preparation (ISO 14780:2017)
ISO 14780:2017 defines methods for reducing combined samples (or increments) to laboratory samples and laboratory samples to sub-samples and general analysis samples and is applicable to solid biofuels.
The methods defined in this document can be used for sample preparation, for example, when the samples are to be tested for calorific value, moisture content, ash content, bulk density, durability, particle size distribution, ash melting behaviour, chemical composition, and impurities.
Biogene Festbrennstoffe - Probenherstellung (ISO 14780:2017)
Dieses Dokument legt Verfahren zur Reduktion von Gesamtproben (oder Einzelproben) auf Laboratoriums-proben und von Laboratoriumsproben auf Teilproben und allgemeine Analysenproben fest und gilt für biogene Festbrennstoffe.
Die in diesem Dokument festgelegten Verfahren können bei der Probenvorbereitung angewendet werden, zum Beispiel, wenn Proben im Hinblick auf Energiegehalt, Wasser- und Aschegehalt, Schüttdichte, mechanische Festigkeit, Partikelgrößenverteilung, Ascheschmelzverhalten, chemische Zusammensetzung und Verunreinigungen zu prüfen sind.
Biocombustibles solides - Préparation des échantillons (ISO 14780:2017)
ISO 14780:2017 définit les méthodes permettant de réduire les échantillons composites (ou les prélèvements élémentaires) en échantillons pour laboratoire et les échantillons pour laboratoire en sous-échantillons et en échantillons pour analyse générale. Elle s'applique aux biocombustibles solides.
Les méthodes définies dans le présent document peuvent être utilisées pour la préparation d'échantillons devant, par exemple, être soumis à des essais portant sur le pouvoir calorifique, le taux d'humidité, la teneur en cendres, la masse volumique apparente, la durabilité, la distribution granulométrique, le comportement des cendres en fusion, la composition chimique et les impuretés.
Trdna biogoriva - Priprava vzorcev (ISO 14780:2017)
Predlagani mednarodni standard opisuje metode za zmanjšanje kombiniranih vzorcev (ali vzorcev) na laboratorijske vzorce in laboratorijskih vzorcev na podvzorce ter splošne analizne vzorce, uporablja pa se tudi za trdna biogoriva. Metode, ki so opisane v tem predlaganem dokumentu, se lahko uporabijo za pripravo vzorcev, ko je potrebno preskusiti na primer kalorično vrednost, vsebnost vlage, vsebnost pepela, prostorninsko maso, odpornost, porazdelitev velikosti delcev, lastnosti pepela pri taljenju, kemično sestavo in nečistoče. Te metode niso namenjene za uporabo pri zelo velikih vzorcih, ki so potrebni za preskušanje premostitvenih lastnosti.
