Solid biofuels - Determination of particle density of pellets and briquettes (ISO 18847:2024)
This document specifies a method for determining the particle density of compressed fuels such as pellets or briquettes. Particle density is not an absolute value and conditions for its determination have to be standardized to enable comparative determinations to be made.
Biogene Festbrennstoffe - Bestimmung der Partikeldichte von Pellets und Briketts (ISO 18847:2024)
Dieses Dokument legt ein Verfahren zur Bestimmung der Partikeldichte von gepressten Brennstoffen, wie z. B. Pellets oder Briketts, fest. Die Partikeldichte ist kein absoluter Wert, und die Bedingungen für deren Bestimmung müssen genormt werden, um vergleichbare Bestimmungen vornehmen zu können.
Biocombustibles solides - Détermination de la masse volumique unitaire des granulés et des briquettes (ISO 18847:2024)
Le présent document spécifie une méthode de détermination de la masse volumique unitaire des combustibles comprimés tels que les granulés ou les briquettes. La masse volumique unitaire n'est pas une valeur absolue et les conditions nécessaires à sa détermination doivent être normalisées afin de pouvoir comparer les différentes déterminations.
Trdna biogoriva - Določevanje gostote delcev peletov in briketov (ISO 18847:2024)
Standard ISO 18847:2016 določa metodo za določevanje gostote delcev v stisnjenih gorivih, kot so peleti in briketi. Gostota delcev ni absolutna vrednost in pogoje za njeno določitev je treba standardizirati, da se omogoči primerjalno določevanje.

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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
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, in collaboration with
the European Committee for Standardization (CEN) Technical Committee CEN/TC 335, Solid biofuels, in
accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 18847:2016), which has been technically
revised.
The main changes are as follows:
— editorial changes made;
— ISO 21945 inserted as a normative reference;
— method for the determination of particle density is specified in more detail;
— informative Annex B on a liquid displacement method to estimate the particle density of pellets added.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.
