This European Standard specifies the determination of particle size distribution of solid recovered fuels. It establishes a manual method for the determination of the maximum projected length for large dimension particles. It applies to both agglomerated and non agglomerated solid recovered fuel pieces exhibiting an irregular shape, such as shredded end-of-life tyres and demolition woods.
This document does not apply to filaments protruding from the SRF pieces.

This European Standard specifies the determination of particle size distribution of solid recovered fuels using an image analysis method. It applies to both agglomerated and non-agglomerated solid, recovered, fuel pieces exhibiting an irregular shape, such as shredded end-of-life tyres and demolition woods. It provides the determination of the maximum projected length as well as parameters such as equivalent diameter. It also gives a characterisation of the filaments protruding from the SRF pieces.

This European Standard specifies three methods of digestion for solid recovered fuels: a) microwave assisted digestion with hydrofluoric, nitric and hydrochloric acid mixture; b) hot water bath digestion of with hydrofluoric, nitric and hydrochloric acid mixture, after ashing of the SRFs sample; c) oven digestion with nitric, perchloric and hydrofluoric acid mixture. Instrumental determination of Si, Al, K, Na, Ca, Mg, Fe, P, and Ti is performed by Inductively Coupled Plasma Spectrometry with optical detection or other suitable spectroscopic techniques such as Flame Atomic Spectroscopy. The effectiveness of the digestion can be verified by qualitative X-ray fluorescence (XRF) analysis on the remaining residue. If necessary an alternative digestion method (among those proposed) needs to be used. XRF can be used for the analysis of Si, Al, K, Na, Ca, Mg, Fe, P, Ti, after ashing (550 °C) of the sample: other elements can be analysed by XRF providing that the concentration levels are above the instrumental detection limits of the XRF instrumentation and after proper preliminary testing. Method a) is recommended for general use, but the amount of the test portion can be very low in case of high concentration of organic matter. Method b) is recommended for SRFs with high organic matter concentration that can be difficult to digest with the other methods. Method c) is recommended for SRFs samples for which the other methods leave a significant insoluble residue. All the listed methods are suitable for the determination of Si, provided that closed containers are used for sample dissolution. XRF is highly recommended for Si, P and Ti analysis.

machine or manual sieving method. It applies to particulate agglomerated and non-agglomerated fuels, such
as fluff, pellets, briquettes, pulverised solid recovered fuels.
This sieving method is not applicable to large pieces with irregular shape such as the pieces of shredded tyres

e.g. an analysis with the laser diffraction method in accordance with ISO 13320.

NOTE 1   The term soft pellet is defined in CEN/TS 15639.
NOTE 2   Particle density is subject to variation due to the susceptibility of organic material to environmental or technical impacts such as air humidity, vibration, abrasion or biodegradation. Therefore, particle density can vary during time thus the measured values should be regarded as a momentary fuel property.
NOTE 3   At the time of preparing this document, the production of briquettes of solid recovered fuels could not be identified in the European market.

NOTE 1   The total moisture content of recovered fuels is not an absolute value and therefore standardised conditions for its determination are indispensable to enable comparative determinations.
NOTE 2   The term moisture content when used with recovered materials can be misleading since solid recovered materials, e.g. biomass, frequently contains varying amounts of volatile compounds (extractives) which can evaporate when determining moisture content by oven drying.

This Technical Specification specifies a method for the determination of bulk density of solid recovered fuels using a standard measuring container. This method is applicable to all solid recovered fuels with a nominal top size of maximal 100 mm.
NOTE 1   The reason for the limitation to maximal 100 mm is the practical maximum volume of a measurement container and thus dimensions of the aperture of the container. Particle dimension should not exceed 1/3 of this value.
NOTE 2   Bulk density of solid recovered fuels is subject to variation due to several impacts such as vibration, shock, pressure, biodegradation, drying and wetting. Measured bulk density can therefore deviate from practice conditions during transportation, storage or transhipment.
