NOTE 1 The nominal top size is defined as the aperture size of the sieve where at least 95 % by mass of the material passes (see CEN/TS 15149‑1).

NOTE 2 Bulk density of solid biofuels is subject to variation due to several factors such as vibration, shock, pressure, biodegradation, drying and wetting. Measured bulk density can therefore deviate from actual conditions during transportation, storage or transhipment.
