Solid recovered fuels - Determination of particle size distribution by screen method
This Technical Specification specifies the determination of particle size and particle size distribution of solid recovered fuels by a machine or manual sieving method. It applies to particulate agglomerated and non-agglomerated fuels, such as fluff, pellets, briquettes, pulverised solid recovered fuels.
NOTE For fine particles 1 mm (e.g. sludges), the use of other methods could give more representative results as e.g. an analyse with the laser diffraction method in accordance with ISO 13320-1 4 .

This Technical Specification (CEN/TS) was approved by CEN on 25 March 2006 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania,

1 Scope
This Technical Specification specifies the determination of particle size distribution of solid recovered fuels by
a machine or manual sieving method. It applies to particulate agglomerated and non-agglomerated fuels, such
as fluff, pellets, briquettes, pulverised solid recovered fuels.
NOTE 1 For fine particles < 1 mm (e.g. sludges), the use of other methods could give more representative results as e.g.
an analysis with the laser diffraction method in accordance with ISO 13320-1 [1].
NOTE 2 This Technical Specification is based on CEN/TS 15149-1 [2] but also applicable to particle sizes less than
3,15 mm.
2 Normative references

dated references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

3 Terms and definitions
For the purpose of this Technical Specification, the terms and definitions given in CEN/TS 15357:2006 apply.
4 Principle
A sample is subjected to sieving through horizontally oscillating sieves, sorting the particles in decreasing size
classes either manual or by machine sieving. For particles less than 25 mm, machine sieving is only used, for
particles greater than 25 mm, manual or machine sieving is applied.
5 Apparatus
5.1 Sieve
5.1.1 General
The sieve (e.g. the geometry of the apertures, the thickness of the sieve, hole distances) shall be in
accordance with ISO 3310-1 and ISO 3310-2. The geometry of the apertures shall be either circular or square
and shall be reported.

CEN/TS 15415:2006 (E)
NOTE For terms regarding sieves and test sieving, see ISO 2395 [3].
For a correct comparison of different sieve analysis, it is necessary to use the same type of sieve with the
same geometry of the apertures for each analysis.
The frame of the sieve shall have a height that enables the sieve to contain the sample and allows a free
movement of the sample during the sieving process.
5.1.2 Minimum sieve area
An appropriate number of either circular or rectangular certified test sieves is required for the test. For
2
particles greater than 10 mm, an effective sieve area of 0,12 m shall be observed. An effective sieve area of
2 2
less than 0,12 m and greater than 0,025 m is adequate for materials with a nominal top size of less than
10 mm.
The geometry of the apertures, the thickness of the sieves, the hole distances and the diameter of the holes
shall be in accordance with ISO 3310-1 and ISO 3310-2. The frame of the sieves shall have a height that
enables the sieves to contain the sample and allows a free movement of the sample during the sieving
process.
5.1.3 Number and size of the sieves
The number of sieves and the aperture sizes of the sieves shall be chosen according to the size specification
of the sample material.
NOTE 1 For solid recovered fuels > 3,15 mm, it is recommended to use sieves with hole diameters of 3,15 mm, 6,3 mm,
12,5 mm, 25 mm, 50 mm, 100 mm and 125 mm, and for solid recovered fuels < 3,15 mm, it is recommended to use sieves
with hole diameters of 200 µm, 400 µm, 800 µm, 1,6 mm and 3,15 mm.
NOTE 2 In order to obtain a complete characterisation of the size range of a sample, the number of sieves should be
such that no more than 25 % of the gross sample mass will be retained on any given sieve. On the biggest and the
smallest sieves no more than 5 % of the gross sample mass should be retained.
NOTE 3 For further resolution in the size distribution and for avoiding any overloading of one fraction, the addition of
sieves in accordance with ISO 565[4] (sieve mesh scale R 20) to the sieve set is also recommended.
5.2 Collecting pan
An adequate number of collecting pans is required for weighing the size classes.
5.3 Flat brush
A flat brush is required for cleaning the sieves, especially in case of fine grade solid recovered fuels.
5.4 Mechanical oscillating equipment
If a mechanical device is used, the shaking operation shall be horizontally oscillating (one or two dimensional),
using an appropriate stroke-frequency according to the type of material. The principle of a mechanical
oscillator is shown in Figure 1.
