Foreword
This document (EN 933-11:2009) has been prepared by Technical Committee CEN/TC 154
“Aggregates”, the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by October 2009, and conflicting national standards
shall be withdrawn at the latest by October 2009.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such
patent rights.
This European Standard is one of a series of standards for tests for geometrical properties of
aggregates. Test methods for other properties of aggregates are covered by parts of the following
European Standards:
EN 932 Tests for general properties of aggregates
EN 1097 Tests for mechanical and physical properties of aggregates
EN 1367 Tests for thermal and weathering properties of aggregates
EN 1744 Tests for chemical properties of aggregates
EN 13179 Tests for filler aggregate used in bituminous mixtures
The other parts of EN 933 are:
Part 1: Determination of particle size distribution - Sieving method
Part 2: Determination of particle size distribution - Test sieves, nominal size of apertures
Part 3: Determination of particle shape - Flakiness index
Part 4: Determination of particle shape - Shape index
Part 5: Determination of percentage of crushed and broken surfaces in coarse aggregate particles
Part 6: Assessment of surface characteristics - Flow coefficient of aggregates
Part 7: Determination of shell content - Percentage of shells in coarse aggregates
Part 8: Assessment of fines - Sand equivalent test
Part 9: Assessment of fines - Methylene blue test
Part 10: Assessment of fines - Grading of fillers (air jet sieving)
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania,
Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

1 Scope
This European Standard describes a simple method for the examination of coarse recycled
aggregates for the purpose of identifying and estimating the relative proportions of constituent
materials. This reference test method should be used for type testing and in case of dispute. For other
purposes, in particular factory production control, other methods may be used provided that an
appropriate working relationship with the reference method has been established.
NOTE 1 This method is not appropriate for lightweight aggregates covered by EN 13055 series.
NOTE 2 If dangerous substances are found in while carrying out this method, they should be dealt with in
accordance with regulations in the place of use.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
EN 932-1, Tests for general properties of aggregates – Part 1 – Methods for sampling
EN 932-2, Tests for general properties of aggregates – Part 2 – Methods for reducing laboratory
samples
EN 932-5, Tests for general properties of aggregates – Part 5 – Common equipment and calibration
EN 933-2, Tests for geometrical properties of aggregates – Part 2: Determination of particle size
distribution – Test sieves, nominal size of apertures
3 Terms and Definitions
For the purpose of this standard, the following terms and definitions apply:
3.1
aggregate size
designation of aggregate in terms of lower (d) and upper (D) sieve sizes expressed as d/D
NOTE This designation accepts the presence of some particles which will be retained on the upper sieve
(oversize) and some which will pass the lower sieve (undersize).
3.2
particle size fraction d /D
i i
fraction of an aggregate passing the larger (D ) of two sieves and retained on the smaller (d)
i i
3.3
constant mass
successive weighings after drying at least 1 h apart not differing by more than 0,1 %
NOTE In many cases constant mass can be achieved after a test portion has been dried for a pre-
determined period in a specified oven at (110 ± 5) °C. Test laboratories can determine the time required to
achieve constant mass for specific types and sizes of sample dependent upon the drying capacit
