Solid biofuels - Determination of particle size distribution - Part 1: Oscillating screen method using sieve apertures of 1 mm and above
This Standard specifies a method for the determination of the size distribution of particulate biofuels by the oscillating 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, e.g. olive stones, nut shells, grain, etc. This Standard applies to particulate compressed and uncompressed fuels with a nominal top size of 3,15 mm and over as e.g. wood chips, hog fuel, olive stones etc.

Ta evropski standard določa metodo za določevanje porazdelitev velikosti delcev določenih biogoriv s horizontalno nihalno zaslonsko metodo. Velja za trdne delce nestisnjenih goriv z nazivno največjo velikostjo 1 mm ali več, kot npr. lesni sekanci, neobdelana mešanica grobih sekancev iz lesenih vlaken in vlaken lubja, olivne koščice itd.

median value of the size distribution value [d50] that separates a distribution into two equal parts and that is graphically the intercept point of the cumulative size distribution curve with the 50 %-horizontal line 4 Principle A sample is subjected to sieving through horizontally oscillating sieves, sorting the particles in decreasing size classes by mechanical means. 5 Apparatus 5.1 Sieves. For the test an appropriate number of either circular or rectangular sieves with a minimum effective sieve area of 1 200 cm2 is required. The geometry of the apertures shall be in accordance with the requirements of
ISO 3310-1 and -2, respectively. The frame of the sieves shall have a height that enables the sieves to contain the sample and allows a free movement of the sample during the sieving process. SIST EN 15149-1:2011
EN 15149-1:2010 (E) 6 NOTE 1 For materials with a nominal top size of less than 10 mm, an effective sieve area of less than 1 200 cm2 is adequate. The number of sieves and the aperture sizes of the sieves shall be chosen according to the size specification of the actual sample material, see EN 14961-1. Sieves should correspond to ISO 3310-1 (1 mm) and
ISO 3310-2 (all aperture sizes above 1 mm). NOTE 2 For samples of wood chips e.g. the following set of sieves may apply: 3,15 mm, 8,0 mm, 16 mm, 31,5 mm, 45 mm, 63 mm. If experience shows that no particles are caught by the larger sieves, t
