Solid biofuels - Determination of water sorption and its effect on durability of thermally treated biomass fuels - Part 1: Pellets (ISO 23343-1:2021)
This document specifies a method for the determination of water sorption in a laboratory setting and provides a measure for how the durability is impacted as a result of immersion in water. Post-immersion durability reduction is calculated as the difference between the durability of the as-received sample and the durability of the wetted product.
Biogene Festbrennstoffe - Bestimmung der Wasseraufnahme und deren Auswirkung auf die Festigkeit von Brennstoffen aus thermisch behandelter Biomasse - Teil 1: Pellets (ISO 23343 1:2021)
Dieses Dokument legt ein Verfahren zur Bestimmung der Wasseraufnahme in einer Laborumgebung fest und stellt ein Maß dafür zur Verfügung, wie die Festigkeit infolge des Eintauchens in Wasser beeinflusst wird. Die Verringerung der Festigkeit nach dem Eintauchen wird als Differenz zwischen der Festigkeit der Probe im Anlieferungszustand und der Festigkeit des benetzten Produkts berechnet.

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.

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).

Introduction
Thermally treated biomass fuels, particularly in compressed form, are increasingly considered as a
replacement of fossil coal or for co-firing in large energy plants for production of heat and/or power.
Compressed biomass fuels which are not thermally treated easily absorb moisture; this compromises
the durability and generates fines. Thermally treated biomass fuels vary in their affinity to absorb
moisture (absorption and/or adsorption – here collectively called sorption) depending on the extent
and/or type of thermal treatment, feedstock used to make the product, compression, potential additives
used, etc. For this purpose, it is important to understand the degree to which thermally treated
compressed solid biofuels are resistant to moisture uptake and the degree to which they maintain
durability when exposed to moisture, primarily in the form of rain during outdoor storage.
Thermally treated biomass fuel such as pellets or briquettes may be classified based on these
characteristics as suitable or unsuitable to be handled and stored under conditions with limited or no
weather protection. This document was developed specifically for the classification of pellets and is not
intended to be applicable to other forms of densified fuel (e.g. briquettes). It is intended that other parts
will be developed as necessary to apply these principles to other forms of thermally treated biomass
fuels.
It should be noted that in large-scale storage of thermally treated biomass fuels the degree of
wetting will likely vary within the storage. Therefore, this document is not intended to be used to
draw conclusions on the average degree of wetting for any particular storage, but rather provides an
indication of the degree to which durability and/or moisture content can be affected under worst case
conditions. This method can be used for comparative purposes towards other pelletized thermally
treated biomass fuels.
