This international standard describes method for determination of the the size distribution of particulate biofuels by the horizontally oscillating screen method. It applies to particulate uncompressed fuels with a nominal top size of 1 mm and above such as wood chips, hog fuel, olive stones etc. A sample is subjected to sieving through horizontally oscillating sieves, sorting the particles in decreasing size classes by mechanical means.The sieving operation shall be horizontally oscillating (one or two dimensional), using an appropriate stroke-frequency according to the type of material. The number of sieves and the aperture sizes of the sieves shall be chosen according to the size specification of the actual sample material.
