(Main)Solid recovered fuels - Determination of bulk density
Solid recovered fuels - Determination of bulk density
This Technical Specification specifies a method for the determination of bulk density of solid recovered fuels using a standard measuring container. This method is applicable to all solid recovered fuels with a nominal top size of maximal 100 mm.
NOTE 1 The reason for the limitation to maximal 100 mm is the practical maximum volume of a measurement container and thus dimensions of the aperture of the container. Particle dimension should not exceed 1/3 of this value.
NOTE 2 Bulk density of solid recovered fuels 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.
Feste Sekundärbrennstoffe - Bestimmung der Schüttdichte
Die Schüttdichte ist eine der Haupteigenschaften von festen Sekundärbrennstoffen (SRF, en: solid recovered fuels). Sie ist zum Beispiel wichtig bei der Probenahme (in Bezug auf das Volumen der Probenahme-einrichtung, das Volumen der Primärprobe), dem Abruf der Transportkapazität oder der erforderlichen Lagerfläche oder der Energiedichte (MWh/m3) eines SRF. Die Schüttdichte ist kein absoluter Wert; daher sollten die Bedingungen für die Bestimmung genormt sein, um vergleichbare Messergebnisse zu erreichen. Diese Technische Spezifikation legt die Bestimmung der Schüttdichte von festen Sekundärbrennstoffen fest, die in einem kontinuierlichen Materialfluss befördert werden können.
Aus praktischen Gründen sind für die Bestimmung zwei Standard-Messbehälter mit einem Nennvolumen von 5 l oder 50 l auswählbar.
Das in dieser Technischen Spezifikation festgelegte Verfahren beruht auf EN 15103 [1].

Foreword
This document (CEN/TS 15401:2010) has been prepared by Technical Committee CEN/TC 343 “Solid
recovered fuels”, the secretariat of which is held by SFS.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document differs from CEN/TS 15401:2006 mainly as follows:
a) results of interlaboratory tests supplemented as an informative Annex A;
b) whole document editorially revised.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria, Croatia, Cyprus,
Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,
Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia,
Spain, Sweden, Switzerland and the United Kingdom.
Introduction
Bulk density is one of the main quality parameters of solid recovered fuels (SRF). It is needed e.g. in a
sampling process (volume of sampling tools, volume primary sample), in assessing transport capacity or
storage space required or energy density (MWh/m ) of SRF. Bulk density is not an absolute value, therefore
conditions for its determination should be standardised in order to gain comparative measuring results. This
Technical Specification specifies the determination of bulk density of solid recovered fuels which can be
conveyed in a continuous material flow.
For practical reasons, two standard measuring containers with a volume of 5 l or 50 l are selectable for the
determination.
The method specified in this Technical Specification is based on EN 15103 [1].
1 Scope
This Technical Specification specifies a method for the determination of bulk density of solid recovered fuels
using a standard measuring container. This method is applicable to all solid recovered fuels with a nominal top
size of maximal 100 mm.
NOTE 1 The reason for the limitation to maximal 100 mm is the practical maximum volume of a measurement
container and thus dimensions of the aperture of the container. Particle dimension should not exceed 1/3 of this value.
NOTE 2 Bulk density of solid recovered fuels 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.
