European foreword
This document (prEN 13383-1:2021) 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 13383-1:2002 and EN 13383-1:2002/AC:2004.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of EU
Regulation(s).
For relationship with Regulation (EU) No 305/2011 on construction products (CPR), see informative
Annex ZA, which is an integral part of this document.
In comparison with the previous edition, the following technical modifications have been made:
a) harmonization of vocabulary and Annex ZA to be consistent with Regulation (EU) No 305/2011 on
construction products (CPR);
b) description of Assessment and Verification Constancy of Performance (AVCP) — type testing and
factory production control;
c) the removal of the previous minimum density requirement and a change in the method of declaring
density;
d) 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;
e) inclusion of a new category CS 105 CS 130 for resistance to breakage and fragmentation/ crushing;
f) inclusion of a new category for resistance to wear MDE 15, to take account of the fact that very few
armourstone sources meet the highest quality category MDE 10;
g) removal of procedures for sample preparation for the Micro-Deval test (now found in
prEN 13383-2);
h) removal of informative Annexes for Guidance on gradings, Guidance on block integrity, Guidance on
the resistance of armourstone to freezing and thawing and to salt crystallization and Additional
explanatory information (now found in prEN 13383-2);
i) inclusion of new Clause 7 “Marking, labelling and packaging”.
The prEN 13383 Armourstone series consists of the following parts:
— Part 1: Characteristics;
— Part 2: Complementary information and test methods.
Provisions for other types of aggregates and their intended uses are specified in the following European
Standards:

The water absorption shall be determined in accordance with prEN 13383-2:2021, Clause 9. The
declaration shall be expressed as a value, stating the means of determination.
4.4.3 Resistance to freezing and thawing
The resistance to freezing and thawing shall be assessed, either:
a) without testing, if the performance of water absorption of such aggregates (not including recycled
aggregates and aggregates originating from blast furnace slag and unaltered porous basalt) is
declared, based on the assessment according to 4.4.2 and the value therein is not greater than 0,5 %;
or
b) based on determination in accordance with 5.1.2.
In case b), the results shall be evaluated against the criterion for the respective class in Table 11.
The results shall be expressed as a class:
1) in case a) as class FT 1/ (WT);
2) in case b) as a class in accordance with Table 11.
