European foreword
This document (prEN 206-1:2024) has been prepared by Technical Committee CEN/TC 104 “Concrete
and related products”, the secretariat of which is held by SN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 206:2013+A2:2021.
In particular, the following main items had been subject to revision when preparing prEN 206-1:2024:
a) Moving all aspects concerning conformity assessment and certification into a separate part
EN 206-2;
b) Annex D on concrete for geotechnical purposes has been moved to a separate part EN 206-3;
c) Opening for national provisions on exposure resistance classes;
d) Included new terminology for binder;
e) Annex M “Guidance on provisions valid in the place of use” moved to Introduction;
f) Annex L “Additional information for specific clauses” included in main text where appropriate;
g) Informative content in Clause 5.1 “Exposure classes” moved to informative Annex C;
h) New Clause 5.4 “Classes regarding CO emissions”;
i) General updates to align with revised EN 1992-1-1:2023;
j) General editorial changes.
This document forms part of three European Standards, written by CEN/TC 104 and covering
specification, performance, production and conformity of concrete.
— Concrete — Specification, performance, production and conformity — Part 1: Performance,
requirements, factory production control and assessment criteria for individual values.
— Concrete — Specification, performance, production and conformity — Part 2: Conformity
assessment and certification.
— Concrete — Specification, performance, production and conformity — Part 3: Additional
requirements for specification and conformity of concrete for special geotechnical works

0 Introduction
0.1 Introduction to EN 206-1
(1) This document defines tasks for the specifier, producer and user.
(2) If the concrete is in conformity with this document, the concrete in the structure is deemed to satisfy
the durability requirements for the intended use in the specific environmental condition, provided:
— the appropriate exposure classes were selected;
— the concrete has the minimum cover to reinforcement in accordance with the relevant design
standard required for the specific environmental condition, e.g. EN 1992-1-1;
— the concrete is properly placed, compacted and cured, e.g. in accordance with EN 13670 or other
relevant standards;
— the appropriate maintenance is applied during the service life.
(3) Concrete conforming to this document may be assumed to satisfy the basic requirements for materials
to be used in all three Execution Classes as defined in EN 13670.
(4) This document also covers the necessary exchange of information between the different parties.
Contractual matters are not addressed. Where responsibilities are given for parties involved, these are
technical responsibilities.
(5) Further explanations and guidance on the application of this document are given in other documents,
such as CEN Technical Reports.
(6) This standard is written in accordance with CEN policy based on the neutrality principle, which
requires that all documents to be written in a way such that conformity with the specified requirements
can be assessed by a manufacturer or supplier (first party), a user or purchaser (second party), or an
independent body (third party). In particular the CEN philosophy of writing 'Product Standards' is
adopted in that the standard gives normative requirements on the product, and not on any party involved
in the manufacturing, testing or distribution of the product.
(7) Figure 1 illustrates the relationships between EN 206 and standards for design and execution,
standards for constituents and test standards.

(9) Provisions for specific products e.g. precast products are given in other European standards for
specific products.
(10) Provisions for specific applications are given in other European Standards, for example:
— concrete to be used in roads and other trafficked areas (e.g. concrete pavements according to
EN 13877-1);
— special technologies (e.g. sprayed concrete according to EN 14487).
(11) Supplementing requirements or different testing procedures are given in some member states for
specific types of concrete and applications, for example:
— concrete for massive structures (e.g. dams);
— dry mixed concrete;
— concrete with a D of 4 mm or less (mortar);
max
— self-compacting concretes (SCC) containing lightweight or heavy-weight aggregates or fibres;
— concrete with open structure (e.g. pervious concrete for drainage).
0.2 Provisions valid in the place of use for EN 206-1
(1) This document will be applied under different climatic and geographical conditions, different levels
of protection and under different, well established, regional traditions and experience. Classes for
concrete properties have been introduced to cover these situations. Where such general solutions were
not possible, the relevant clauses contain permission for the application of provisions valid in the place
of use of the concrete.
(2) National choice is allowed in this document where explicitly stated that provisions valid in the place
of use may be given.

5 Classification
5.1 Exposure classes related to environmental actions
(1) The environmental exposure conditions are those chemical, physical and biological conditions to
which the structure is exposed (additional to the mechanical actions). See Annex C.
5.2 Classes for properties of fresh concrete
5.2.1 Consistence classes
(1) Where concrete is classified with respect to consistence, Tables 1, 2, 3 and 4 apply. In the case of SCC,
only the classes in Table 4 apply.
(2) Consistence may also be specified by a target value with tolerances as given in Table 25.
NOTE The classes of consistence in Tables 3 to 6 are not directly related. For earth moist concrete, i.e. concrete
with low water content designed to be compacted in special processes, the consistence is not classified.
