Overview

This pre-standard specifies a method for the determination of particle density of irregularly shaped pieces of compressed fuels such as pellets or briquettes. It is not applicable to soft or semi-soft pellets. For the determination of particle density both mass and volume of an individual particle or a group of particles are determined. The volume is measured by determining the buoyancy in a liquid. This procedure follows the physical principle that the buoyancy of a body is equal to the mass of the displaced volume of a liquid. The apparent loss in mass between a measurement in air and a subsequent measurement in liquid marks its buoyancy. The volume of the sample is calculated via the density of the applied liquid. Particle density is subject to variation due to the susceptibility of organic material to environmental or technical impacts such as air humidity, vibration, abrasion, biodegradation, changes. Therefore, particle density can vary during time; thus the measured values should be regarded as a momentary fuel property. CEN/TS 15405 which has been published as DIN SPEC 1152, has been prepared by Technical Committee CEN/TC 343 "Solid Recovered Fuels", the secretariat of which is held by SFS (Finland). At NMP the responsible German Working Committee is NA 062-05-83 AA "Sekundärbrennstoffe" ("Recovered fuels").
