Bibliography

This European Standard describes a method of determining bulk density of solid biofuels by the use of a standard measuring container. This method is applicable to all solid biofuels with a nominal top size of maximum 100 mm.Bulk density is not an absolute value, therefore conditions for its determination have to be standardised in order to gain comparative measuring results.NOTE 1The 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 2Bulk 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.
