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, e.g. wood chips, hog fuel, olive stones. The method is intended to characterize material up to a particle size class (P) of P63. For larger P-classes and PL-classes, the characterization is mainly done by hand sorting. NOTE            The definitions and specifications of P- and PL-classes are given in ISO 17225-1, ISO 17225-4 and ISO 17225-9.
