Solid biofuels. Determination of particle size distribution - Vibrating screen method using sieve apertures of 3,15 mm and below

BS EN 15149-2:2010 Solid biofuels. Determination of particle size distribution. Vibrating screen method using sieve apertures of 3,15 mm and below

BS EN 15149-2 is a European Standard which specifies a method for the determination of the size distribution of particulate biofuels by the vibrating 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. This document applies to particulate uncompressed fuels with a nominal top size of 3,5 mm and below (e.g. sawdust).
