European foreword
This document (EN 933-5:2022) 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 May 2023, and conflicting national standards shall be
withdrawn at the latest by May 2023.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 933-5:1998.
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association.
In comparison with the previous edition, the following technical modifications have been made:
a) The title has been revised to better reflect the scope;
b) Clause 1: Scope has been clarified to show that the standard applies to coarse and all-in natural
aggregates, but not to lightweight aggregates.
c) Clause 3: The definition of a crushed surface has been changed. The definitions of aggregate size and
a rounded particle have been deleted. The definition of a rounded surface has been added;
d) Clause 4: Principle has been amended;
e) Clause 5: Coloured pencil has been added as optional apparatus to facilitate the procedure of
estimating crushed and rounded parts of a particle surface;
f) Clause 6: Preparation of test portion has been revised;
g) Clause 7: Procedure has been amended and an illustrating figure has been added;
h) Clause 8: Calculation and expression of results has been amended;
i) Clause 9: The lists of required and optional data have been updated;
j) New informative Annex A, with guidance for estimated mass of various size fractions with about 100
particles, has been added;
k) New informative Annex B, with example of application of the test procedure, has been added;
l) Previous Annex A, with example of a test data sheet, has been revised and moved to Annex C.
This document forms part of a series of tests for geometrical properties of aggregates. Test methods for
other properties of aggregates are covered by the following European Standards:
— EN 932 (all parts), Tests for general properties of aggregates
— EN 1097 (all parts), Tests for mechanical and physical properties of aggregates
— EN 1367 (all parts), Tests for thermal and weathering properties of aggregates
— EN 1744 (all parts), Tests for chemical properties of aggregates
— EN 13179 (all parts), Tests for filler aggregate used in bituminous mixtures
The other parts of the EN 933 series include:
— 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 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 filler aggregates (air jet sieving)
— Part 11: Classification test for the constituents of coarse recycled aggregate
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and the United
Kingdom.
1 Scope
This document specifies the reference method, used for type testing and in case of dispute, for the
determination of the percentages of crushed particles, totally crushed particles and totally rounded
particles in coarse and all-in natural aggregates. Other methods can be used for other purposes, such as
factory production control, provided that an appropriate working relationship with the reference method
has been established.
NOTE 1 Examples of advanced test methods can be found in the Bibliography.
This document applies to coarse aggregates comprising particles within size fraction 4/63 mm. It does
not apply to lightweight aggregates.
NOTE 2 For coarse aggregate between 4 mm and 20 mm the percentages of crushed surfaces are linked to the
flow coefficient and can therefore be used in association with the test method specified in EN 933-6.
Clause 7.1 specifies the procedure for test portions consisting of one size fraction and Clause 7.2 specifies
the procedure for test portions consisting of two or more size fractions.
Guidance for the estimated mass of various size fractions with about 100 particles is given in informative
Annex A.
Examples of application of the test procedure and an example of a test data sheet are given in informative
Annexes B and C.
