This document specifies a method for the determination of the size distribution of particulate biofuels by the vibrating 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 uncompressed fuels with a nominal top size of 3,15 mm and below (for example, sawdust). A laboratory sample is subjected to sieving through vibrating sieves, sorting the particles in decreasing size classes by mechanical means. The determination of particle size distribution includes the following parts under the general title "Solid biofuels - Determination of particle size distribution for uncompressed fuels": - "Part 1: Oscillating screen method using sieves with apertures of 3,15 mm and above" and - "Part 2: Vibrating screen method using sieves with aperture of 3,15 mm and below". This document has been prepared by Technical Committee ISO/TC 238 "Solid biofuels" in collaboration with 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 "Biogene Festbrennstoffe" ("Solid biofuels") at DIN Standards Committee Materials Testing (NMP).
