EN ISO 17828:2025

This document specifies a method for determining the bulk density of solid biofuels using a standardized measuring container. This method is applicable to all pourable solid biofuels with a nominal top size of maximum 63mm while the maximum particle length is 200mm. For fuels with a nominal top size larger than 63mm, a different method is described.Bulk density is not an absolute value; therefore, conditions for its determination have to be standardized in order to gain comparative measuring results.NOTE 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.
