Solid biofuels- Determination of particle size distribution - Part 2: Vibrating screen method using sieve apertures of 3,15 mm and below; German version EN 15149-2:2010
Feste Biobrennstoffe - Bestimmung der Partikelgrößenverteilung - Teil 2: Rüttelsiebverfahren mit Sieb-Lochgrößen von 3,15 mm und darunter; Deutsche Fassung EN 15149-2:2010
Overview
This standard specifies a method for the determination of the size distribution of particulate biofuels by the vibrating screen method. The method specified 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 uncompressed fuels with a nominal particle size of 3,5 mm and below (for instance, sawdust). For the method specified, a sample is subjected to sieving through vibrating sieves, sorting the particles in decreasing size classes by mechanical means. A manual sieving is excluded due to the fact that small sieve holes can easily be clogged by particles. The standard has been prepared by Technical Committee CEN/TC 335 "Solid biofuels", the secretariat of which is held by SIS (Sweden). The responsible German Committee is Working Committee NA 062-05-82 AA "Feste Biobrennstoffe" ("Solid biofuels") at NMP.
