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.

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.
