Solid biofuels - Methods for the determination of particle size distribution - Part 2: Vibrating screen method using sieve apertures of 3,15 mm and below

This Technical Specification specifies a method for the determination of the size distribution of particulate biofuels by the oscillating screen method. The method described is meant for particulate biofuels only, namely materials that either have been reduced in size, such as most wood fuels, or are physically in a particulate form. This document applies to particulate fuels with a nominal top size less than 3,15 mm (e.g. sawdust).

This Technical Specification (CEN/TS) was approved by CEN on 4 June 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, Romania,
Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

Foreword
This Technical Specification (CEN/TS 15149-2:2006) has been prepared by Technical Committee
CEN/TC 335 “Solid Biofuels”, the secretariat of which is held by SIS.
CEN/TS 15149 consists of the following parts under the general title Solid biofuels - Methods for the
determination of particle size distribution:

Part 2: Vibrating screen method using sieve apertures of 3,15 mm and below
Part 3: Rotary screen method
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, 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 United Kingdom.

Introduction
Part 1 describes the reference method for size classification of samples with a nominal top size of 3,15 mm
and over.
Part 2 describes the reference methods for all samples with a nominal top size below 3,15 mm.
Part 3 describes an innovative method, by which the degree of overestimating the fine particle fractions is
reduced. As it is currently not generally available, it is here proposed, for research and development purposes
or for individual quality management processes, that the quality requirements are bilaterally defined between
the suppliers and consumers based on this method.
NOTE The nominal top size is defined as the aperture size of the sieve where at least 95 % by mass of the material
passes (see bibliography)
