Solid biofuels - Determination of bulk density (ISO 17828:2025)
This document specifies a method for determining the bulk density of solid biofuels using a standardized measuring container. This method is applicable to all pourable solid biofuels with a nominal top size of maximum 63 mm while the maximum particle length is 200 mm. For fuels with a nominal top size larger than 63 mm, a different method is described.
Bulk density is not an absolute value; therefore, conditions for its determination have to be standardized in order to gain comparative measuring results.
NOTE Bulk density of solid biofuels is subject to variation due to several factors such as vibration, shock, pressure, biodegradation, drying, and wetting. Measured bulk density can therefore deviate from actual conditions during transportation, storage, or transhipment.
Biogene Festbrennstoffe - Bestimmung der Schüttdichte (ISO 17828:2025)
Dieses Dokument legt ein Verfahren zur Bestimmung der Schüttdichte von biogenen Festbrennstoffen unter Verwendung eines genormten Messbehälters fest. Dieses Verfahren ist anwendbar auf sämtliche schüttbaren biogenen Festbrennstoffe mit einer nominellen Siebgröße von höchstens 63 mm bei einer maximalen Partikellänge von 200 mm. Für Brennstoffe mit einer nominellen Siebgröße von mehr als 63 mm wird ein anderes Verfahren beschrieben.
Die Schüttdichte ist kein absoluter Wert; daher müssen die Bedingungen für deren Bestimmung genormt sein, um vergleichbare Messergebnisse zu erreichen.
ANMERKUNG Die Schüttdichte von biogenen Festbrennstoffen unterliegt Schwankungen aufgrund mehrerer Faktoren, wie z. B. Erschütterung, Stoß, Druck, biologischer Abbau, Trocknen und Befeuchten. Die gemessene Schüttdichte kann daher von den tatsächlichen Bedingungen während des Transports, der Lagerung oder Umladung abweichen.
Biocombustibles solides - Détermination de la masse volumique apparente (ISO 17828:2025)
Le présent document spécifie une méthode pour déterminer la masse volumique apparente des biocombustibles solides à l’aide d’un récipient-mesure normalisé. Cette méthode s’applique à tout biocombustible solide versable dont la dimension nominale est inférieure ou égale à 63 mm, tandis que la longueur des particules est inférieure ou égale à 200 mm. Pour les combustibles dont la dimension nominale est supérieure à 63 mm, une méthode différente est décrite.
La masse volumique apparente n’étant pas une valeur absolue, il est indispensable de normaliser les conditions de sa détermination afin d’obtenir des résultats de mesure comparatifs.
NOTE La masse volumique apparente des biocombustibles solides est soumise à des variations aux causes diverses telles que vibrations, chocs, pression, biodégradation, séchage et mouillage. La masse volumique apparente mesurée peut, par conséquent, s’écarter de celle observée en conditions réelles lors du transport, du stockage ou du transbordement.

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 on the ISO list of
patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 238, Solid biofuels
This second edition cancels and replaces the first edition (ISO 17828:2016), which has been technically
revised.
The main changes are as follows:
— The introduction was changed;
— The dimensions of the small standardised container were modified to better reflect industry standard
equipment. The volume was not changed.
— The scope was expanded to cover coarse fuels having a nominal top size larger than 63 mm;
— A procedure for measuring bulk density of such coarse fuels was added;
— For such coarse fuels a new measuring container was defined;
— For fuels having a nominal top size of 63 mm and below, an optional use of an apparatus for controlled
shock exposure is described. An example of such apparatus is added as informative Annex B;
— An option to use a spill prevention aid was included;
— The rule for rounding of the reported result was changed;
— Changes were made in the test report section.
Any feedback or questions on this document should be directed to the user’s national standards body. A
