This European Standard was approved by CEN on 30 December 2011.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national
standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN member.

This European Standard exists in three official versions (English, French, German). A version in any other language made by translation
under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has the same
status as the official versions.

Foreword
This document (EN 932-5:2012) 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text or by endorsement, at the latest by August 2012, and conflicting national standards shall be withdrawn at
the latest by August 2012.
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 document supersedes EN 932-5:1999.
This standard forms part of a series of standards for general properties of aggregates. Test methods for other
properties of aggregates are covered by the following European Standards:
EN 933, Tests for geometrical 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 932, Tests for general properties of aggregates are:
 Part 1: Methods for sampling;
 Part 2: Methods for reducing laboratory samples;
 Part 3: Procedure and terminology for simplified petrographic description;
 Part 6: Definitions of repeatability and reproducibility.
In the bibliography, reference is made to the International Organization for Legal Metrology (OIML)
classification, which this standard has adopted for the purposes of establishing a frequency of calibration for
balance weights.
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, Croatia, 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, Turkey and the United Kingdom.

1 Scope
This European Standard specifies general requirements for common equipment, calibration and checking
procedures and reagents for the testing of the properties of aggregates.
In the case of checking, other procedures than the ones described in this standard may be used provided that
appropriate working relationships with the corresponding methods described in this standard have been
established. In case of dispute, the checking methods described in this standard shall be used.
