This European Standard specifies the determination of particle size distribution of solid recovered fuels by a machine or manual sieving method. It applies to particulate agglomerated and non-agglomerated fuels, such as fluff, pellets, briquettes, pulverised solid recovered fuels. This sieving method is not applicable to large pieces with irregular shape such as the pieces of shredded tyres or of demolition wood. In the case, of large pieces of irregular shape, prEN 15415-2 and prEN 15415-3 are applicable. NOTE 1 For fine particles < 1 mm (e.g. sludges), the use of other methods could give more representative results as e.g. an analysis with the laser diffraction method in accordance with ISO 13320. NOTE 2 This European Standard is based on EN 15149-1 applicable to particle sizes less than 3,15 mm.
