This Technical Specification (CEN/TS) was approved by CEN on 19 March 2005 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia,
Slovenia, Spain, Sweden, Switzerland and United Kingdom.

Foreword
This Technical Specification (CEN/TS 15103:2005) has been prepared by Technical Committee CEN/TC 335
“Solid Biofuels”, the secretariat of which is held by SIS.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this CEN Technical Specification: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland
and United Kingdom.
Introduction
Bulk density is an important parameter for fuel deliveries on volume basis and together with the net calorific
value it determines the energy density. It allows conclusions on the required storage or transportation room
demand. This Technical Specification describes the determination of the bulk density of pourable solid
biofuels which can be conveyed in a continuous material flow.
For practical reasons two standard measuring containers with a volume of 5 litres or 50 litres were chosen for
the determination. Due to the limited volume of these containers, some fuels are therefore excluded from the
scope of this Technical Specification. This, for example, applies for chunk wood, uncomminuted bark or for
baled material and larger briquettes. A bulk density determination of such fuels can be conducted by applying
fuel quantities and transhipment containment (e.g. lorries, containers) as typical for the given site.
For conclusion on the actual storage room requirement of a solid biofuel the different storage conditions (e.g.
height of heap, moisture content), which usually differ largely from the sample volume of the standard
measuring container, have also to be taken into account.
1 Scope
This Technical Specification describes a method of determining bulk density of solid biofuels by the use of a
standard measuring container. This method is applicable to all solid biofuels with a nominal top size of
maximum 100 mm.
Bulk density is not an absolute value, therefore conditions for its determination have to be standardised in
order to gain comparative measuring results.
NOTE 1 The nominal top size is defined as the aperture size of the sieve where at least 95 % by mass of the material
passes (see normative reference 2a)
NOTE 2 Bulk density of solid biofuels is subject to variation due to several impacts such as vibration, shock, pressure,
biodegradation, drying and wetting. Measured bulk density can therefore deviate from practice conditions during
transportation, storage or transhipment.
