Foreword
This document (prEN 13383-1:2015) has been prepared by Technical Committee CEN/TC 154 “Aggregates”,
the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13381-1:2002.
This European Standard has been prepared under a mandate given to CEN by the European Commission
and the European Free Trade Association, and supports essential requirements of Construction Products
Regulation (EU) No. 305/2001.
For relationship with EU Regulation, see informative Annex ZA, which is an integral part of this document.
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.
The most significant technical changes compared to the previous edition include:
a) Harmonization of vocabulary and Annex ZA to be consistent with Construction Products Regulations
b) Description of assessment and verification of conformity of performance of aggregates (AVCP) – type
testing and factory production control in a separate new standard prEN 16236;
c) Inclusion of general sentences on dangerous substances and adding a new normative Annex A dealing
with all source materials considered;
d) The removal of the previous minimum density requirement and a change in the method of declaring
density;
e) Inclusion of a new coarse grading (32/90 mm) and a new light grading (15 kg to 120 kg) and guidance on
the declaration of non-standard heavy gradings;
f) Inclusion of a new category for resistance to wear MDE15, to take account of the fact that very few
armourstone sources meet the highest quality category MDE10;
g) Removal of procedures for sample preparation for the Micro-Deval test (now found in EN 13383-2);
In this document the terms ‘property’ and ‘characteristic’ have the same meaning.
Requirements for assessment and verification of constancy of performance are given in prEN 16236 on
Evaluation of conformity of aggregates.
EN 13383 Armourstone consists of the following parts:
— Part 1: Specifications
— Part 2: Test methods
Requirements for other end uses of aggregates are specified in the following European Standards:

1 Scope
This European Standard specifies the properties of aggregates obtained by processing natural, manufactured
or recycled materials and mixtures of these materials for use as armourstone.
A list of the source materials that have been considered and are within the scope of this European Standard is
given in Annex A (normative).
Requirements for the Assessment and Verification of the Constancy of Performance (AVCP) of armourstone
to this European Standard are given in prEN 16236.
Armourstone used in construction shouldl conform with all the requirements of this European Standard. The
standard includes specific requirements for natural armourstone, ferrous and steel making slag and recycled
armourstone.
Finer aggregates than specified in this European Standard are used in hydraulic structures. For such
aggregates European Standards for other end uses of aggregates should be applied.

4 General requirements
Where conformity with a category is based on a value of a property being less than or equal to a given value,
conformity with a more severe category (lower value) automatically confers conformity with all less severe
categories (higher values). Similarly for categories based on the value of a property being greater than or
equal to a given value, conformity with a more severe (higher value) automatically confers conformity with all
less severe categories (lower values).
When the value of a property is required but not defined by specified limits the value should be declared by
category, e.g. in Table 7 the percentage by number of pieces of armourstone
the manufacturer as an XX
Declared
with less than 50 % crushed or broken surfaces of say 7 corresponds to RO .
When a property is not required, a “No requirement” category may be used.
Sampling shall be carried out as specified in prEN 13383-2:2015, Clause 4.
5 Geometrical requirements
5.1 General
The necessity for testing and declaring all properties in this clause is limited according to the particular
application at end use or origin of the armourstone. When required, the tests specified in Clause 5 shall be
carried out to determine appropriate geometrical properties.
5.2 Gradings
5.2.1 Coarse gradings

use and when required, provisions valid at the place of use can be used to assess its suitability.
Sampling shall be carried out as specified in prEN 13383-2:2015, Clause 4.
7.2 Impurities
Armourstone shall not contain any foreign matter such as scrap metal, wood and plastic in a quantity that will

7.3 Water soluble constituents
When a determination of water soluble constituents is required, an eluate shall be prepared from a
representative sample of armourstone as specified in EN 1744-3. Where suitable aggregate representative of
the armourstone is not available, the test portion shall be obtained by crushing, using a laboratory jaw crusher,
at least six separate pieces of armourstone for which the masses do not differ by more than 25 %.
7.4 Dangerous substances
National regulations on dangerous substances may require verification and declaration on release, and
sometimes content, when construction products covered by this standard are placed on those markets.
In the absence of European harmonized test methods, verification and declaration on release/content should
be done taking into account national provisions in the place of use.
