This document specifies a method for the determination of the size distribution of particulate biofuels by the horizontally oscillating screen method. It applies to particulate uncompressed fuels with a nominal top size of 3,15 mm and above, such as wood chips, hog fuel, olive stones, etcetera. A laboratory sample is subjected to sieving through horizontally oscillating 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).
