Common rules for precast concrete products
This European Standard specifies the requirements, the basic performance criteria and the evaluation of conformity for unreinforced, reinforced and prestressed precast concrete products made of compact light-, normal- and heavyweight concrete according to EN 206-1 with no appreciable amount of entrapped air other than entrained air. Concrete containing fibres for other than mechanical properties steel, polymer or other fibres is also covered. It does not cover prefabricated reinforced components of lightweight aggregate concrete with open structure. It may also be used to specify products for which there is no standard. Not all of the requirements (Clause 4) of this standard are relevant to all precast concrete products. If a specific product standard exists, it takes precedence over this standard. The precast concrete products dealt with in this standard are factory produced for building and civil engineering works. This standard may also be applied to products manufactured in temporary plants on site if the production is protected against adverse weather conditions and controlled following Clause 6 provisions. The analysis and design of precast concrete products is not within the scope of this standard but it does offer, for non-seismic zones, information about: - the choice of partial safety factors defined by the pertinent Eurocode; - the definition of some requirements for prestressed concrete products.
Allgemeine Regeln für Betonfertigteile
Diese Europäische Norm führt die Anforderungen an, die grundlegenden Leistungskriterien für und die Kon-formitätsbewertung von bewehrten und nicht bewehrten Spannbetonfertigteilen aus Leicht-, Normal und Schwerbeton (mit einer Dichte im ofentrockenen Zustand von 800 kg/m3 bis 2 000 kg/m3 bzw. 2 000 kg/m3 bis 2 600 kg/m3 bzw. von mehr als 2 600 kg/m3) auf, der so verdichtet wurde, dass er außer den Luftporen keine nennenswerten Lufteinschlüsse enthält. Sie gilt nicht für bewehrte Betonfertigteile aus haufwerksporigem Leichtbeton.
Diese Norm ist allgemein auf alle Arten von Fertigteilen anwendbar und kann als allgemeines Bezugsdoku-ment in speziellen Produktnormen herangezogen werden.
Wenn eine spezielle Produktnorm vorliegt, hat sie Vorrang gegenüber dieser Norm.
Die in der vorliegenden Norm behandelten Fertigteile sind werkmäßig in Serie oder in Einzelanfertigung her-gestellte Bauteile für den Hoch- und Ingenieurbau. Diese Norm kann auch auf Produkte angewendet werden, die in temporären Anlagen auf der Baustelle hergestellt werden, wenn die Herstellung gegen ungünstige Witterungseinflüsse geschützt ist und nach den Vorgaben in Abschnitt 6 kontrolliert wird.
Règles communes pour les produits préfabriqués en béton
La présente Norme Européenne spécifie les prescriptions, les critères relatifs aux performances de base et l’évaluation de la conformité des produits préfabriqués non armés, armés et précontraints en béton léger, normal et lourd conformément à l’EN 206-1, sans quantité notable d’air occlus autre que l’air entraîné. . Elle couvre également le béton contenant des fibres (acier, polymère ou autre) pour d’autres propriétés que les propriétés mécaniques. Elle ne couvre pas les produits préfabriqués armés en béton de granulats légers à structure ouverte
Elle peut aussi être utilisée pour spécifier des produits pour lesquels il n’existe pas de norme. Les prescriptions (Article 4) de la norme ne sont pas toutes applicables à l’ensemble des produits préfabriqués en béton.
Si une norme de produit spécifique existe, elle a priorité sur la présente norme.
Les produits préfabriqués en béton considérés dans la présente norme sont fabriqués en usine et destinés à des bâtiments ou des ouvrages de génie civil. La présente norme peut également être appliquée à des éléments fabriqués dans des installations provisoires sur chantier, à condition que la fabrication soit protégée contre les conditions environnementales néfastes et soit contrôlée selon les prescriptions de l’Article 6.
L’analyse et le calcul de produits préfabriqués en béton ne sont pas inclus dans cette norme mais elle donne, pour les zones non sismiques, des informations sur :
- le choix de coefficients de sécurité partiels définis par l’Eurocode correspondant ;
- la définition de quelques prescriptions pour les produits en béton précontraint.
Skupna pravila za montažne betonske izdelke
Ta evropski standard določa zahteve, osnovna merila učinkovitosti in vrednotenje skladnosti za montažne izdelke iz nearmiranega, armiranega in prednapetega kompaktnega betona, ki je lahek, normalen ali težek, v skladu s standardom EN 206-1 brez znatne količine ujetega zraka, razen primešanega zraka. Standard zajema tudi beton, ki vsebuje vlakna zaradi drugih razlogov, kot so mehanske lastnosti, jeklo, polimer ali druga vlakna. Standard ne zajema montažnih armiranih komponent iz lahkega betona za agregate z odprto konstrukcijo. Uporablja se lahko tudi za določanje izdelkov, za katere standard ne obstaja. Vse zahteve (točka 4) tega standarda ne veljajo za vse montažne betonske izdelke. Če obstaja poseben standard za izdelek, ima prednost pred tem standardom. Montažni betonski izdelki, obravnavani v tem standardu, so tovarniško proizvedeni za stavbe in gradbene inženirske objekte. Ta standard se lahko uporablja tudi za izdelke, proizvedene v začasnih obratih na delovišču, če je proizvodnja zaščitena pred negativnimi vremenskimi pogoji in nadzorovana v skladu z določbami iz točke 6. Analiza in načrtovanje montažnih betonskih izdelkov nista predmet tega standarda, vendar za območja, ki niso potresna, nudi informacije o: – izbiri delnih varnostnih dejavnikov, ki jih določa zadevni evrokod; – opredelitvi nekaterih zahtev za prednapete betonske izdelke.

EN 13369:2013 (E) 6 Introduction This document is intended to outline the general common requirements applicable to a large variety of precast concrete products manufactured in a factory environment. It acts as a reference standard for other standards to enable a more consistent approach to standardization in the field of precast concrete products and to reduce the variations brought about by a large number of standards produced in parallel by different groups of experts. At the same time, it allows those experts the flexibility to include variations in specific product standards where they are required. This standard has been produced as part of the total CEN programme for construction and refers to the relevant specifications of associated standards EN 206 (all parts) for concrete and EN 1992 for the design of concrete structures. The installation of some precast concrete products is dealt with by EN 13670.
As it is not a harmonised standard, it may not be used on its own for the purpose of CE marking of precast concrete products. The design of precast concrete products should be verified to ensure the fitness of their properties for the particular application, particular attention being paid to design co-ordination with other parts of the construction. SIST EN 13369:2013
EN 13369:2013 (E) 7 1 Scope This European Standard specifies the requirements, the basic performance criteria and the evaluation of conformity for unreinforced, reinforced and prestressed precast concrete products made of compact light-, normal- and heavyweight concrete according to EN 206-1 with no appreciable amount of entrapped air other than entrained air. Concrete containing fibres for other than mechanical properties steel, polymer or other fibres is also covered. It does not cover prefabricated reinforced components of lightweight aggregate concrete with open structure.
It may also be used to specify products for which there is no standard. Not all of the requirements (Clause 4) of this standard are relevant to all precast concrete products. If a specific product standard exists, it takes precedence over this standard. The precast concrete products dealt with in this standard are factory produced for building and civil engineering works. This standard may also be applied to products manufactured in temporary plants on site if the production is protected against adverse weather conditions and controlled following Clause 6 provisions. The analysis and design of precast concrete products is not within the scope of this standard but it does offer, for non-seismic zones, information about: the choice of partial safety factors defined by the pertinent Eurocode; the definition of some requirements for prestressed concrete products. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

For a particular material, the establishment of suitability may be based on a European Standard which refers specifically to the use of this material in concrete or in precast concrete products; in absence of a European Standard, it may also result, under the same conditions, from an ISO Standard. Where this material is not covered by a European or ISO Standard, or if it deviates from the requirements of these standards, the establishment of suitability may be based on: the provisions valid in the place of use of the precast concrete product which refer specifically to the use of this material in concrete or in precast concrete products; or a European Technical Approval specifically for the use of this material in concrete or precast concrete products. 4.1.2 Constituent materials of concrete 4.1.2.1 General EN 206-1:2000, 5.1 shall apply. 4.1.2.2 Reclaimed crushed and recycled coarse aggregates Reclaimed crushed and recycled coarse aggregates, mixed in concrete with other aggregates, shall not adversely alter the rate of setting and hardening of concrete, nor shall it be detrimental to the durability of the precast concrete product in the end use conditions. SIST EN 13369:2013
EN 13369:2013 (E) 11 The amount of crushed recycled aggregates obtained from precast concrete products manufactured in the same factory, can be used up to 10 % in weight of the total content of aggregates in the concrete mix with no further testing of the mechanical strength of the product or of hardened concrete properties other than testing of compressive concrete strength. Where required and for specific applications, the amount of reclaimed aggregates might be limited to 5 % in weight. More detailed recommendations on the use of reclaimed crushed and recycled coarse aggregates are given in Annex Q.
Alternative provisions are under development in the upcoming version of EN 206-1 and should be considered. 4.1.3 Reinforcing steel Reinforcing steel (bars, coils and welded fabric) shall comply with EN 10080. Other types of reinforcing steel may be used according to provisions valid in the place of use of the product (e.g. EN 1992-1-1:2004, 3.2). NOTE Recommendations on indented bars and wires are given in Annex N. 4.1.4 Prestressing steel Prestressing steel (wire, bars and strand) shall comply with prEN 10138-1, prEN 10138-2, prEN 10138-3 and prEN 10138-4. Other types of prestressing steel may be used according to provisions valid in the place of use of the product (e.g. EN 1992-1-1:2004, 3.3). 4.1.5 Inserts and connectors Mechanical inserts and connectors shall: a) resist the design actions; b) have the necessary ductility. Permanent connecting parts and fasteners shall maintain these properties for the design working life of the precast concrete product. Provisions valid in the place of use of the product shall be taken into account. NOTE Recommendations for the design of some anchors can be found in CEN/TS 1992-4 (all parts); recommendations for the design of lifting and handling devices, can be found in CEN/TR 15728. 4.2 Production requirements 4.2.1 Concrete production 4.2.1.1 General For concrete composition, type of cement, use of aggregates, additions and admixtures, and for resistance to alkali-silica reaction, chloride content, air content and concrete temperature, EN 206-1:2000, 5.2 and 5.3 shall apply. For specification of concrete EN 206-1 shall apply. SIST EN 13369:2013
EN 13369:2013 (E) 12 NOTE When concrete is specified by the manufacturer, basic requirements (EN 206-1:2000, 6.2.2) are given in the design documentation and additional requirements (EN 206-1:2000, 6.2.3) are normally not relevant for precast concrete. 4.2.1.2 Placing and compaction of concrete Concrete shall be placed and compacted so as to retain no appreciable amount of entrapped air other than entrained air (e.g. to achieve sufficient frost resistance) to avoid detrimental segregation and to ensure that the reinforcement shall be properly embedded. 4.2.1.3 Curing (protection against drying out) The concrete shall be protected during curing so that loss in strength and cracking due to temperature and shrinkage and that, if relevant, detrimental effects on durability, are avoided. All surfaces of newly cast concrete may be protected by one of the methods listed in Table 1 or by any other method applicable in the place of use, unless it is shown by tests and inspection on the finished product or on representative samples, that other means are relevant in the production environment. Table 1 — Protection against drying out Method Typical means of protection A - Without addition of water keeping the concrete in an environment with a relative humidity above 65 % for CEM I and CEM II/A, 75 % for all the other types of binders; keeping the formwork in place; covering the concrete surface with vapour-resistant sheets
B - Keep the concrete moist by addition of water maintaining wet coverings on the concrete surface; keeping the concrete surface visibly wet by spraying with water C – Use of curing compounds Curing compounds used shall conform to provisions valid in the place of use
For methods A and B, the protection shall be maintained until the compressive strength of the sample at the end of curing (fc,cure) is equal to or greater than the smallest value of the parameters Dd.fck and fc,L (cylinders or cubes). The parameters Dd et fc,L are defined in Table 2. fc,cure ≥ MIN (Dd.fck ; fc,L) (1) NOTE fck is the characteristic compressive strength of the concrete at the age of 28 days targeted by the manufacturer. The measure of the mean compressive strength fc,cure shall be done on concrete samples that are submitted to the same protection against drying out as the product. For design working life of more than 50 years, or for specific local environmental conditions, other values may be given following the requirements valid in the place of use. The degree of hardening in Table 2 may either be measured by testing a concrete sample or estimated by calculation using a hardening law based on initial type testing or the maturity concept. The test result shall be obtained from an individual specimen or the average of the results when two or more specimens made from one sample are tested at the same age. SIST EN 13369:2013

Other means than those defined in Table 2 may be employed if the value of the water absorption of the concrete, measured according to the test procedure defined in Annex G, does not exceed 10 % (in relative proportion) of the value of water absorption of the concrete complying with the requirements in Table 1. The water absorption test is run on (30 ± 1) mm thick samples that include the surface exposed to the environment. 4.2.1.4 Accelerated hydration by heat treatment Where heat treatment at atmospheric pressure is applied to concrete during production in order to accelerate its hardening, it shall be demonstrated by initial testing that the required strength is achieved for each concrete family concerned. Depending on material and climatic conditions, more restricting requirements may apply to the heat treatment of outdoor products in certain areas according to provisions valid in the place of use. The following conditions shall be fulfilled when the maximum mean temperature Tmean within the concrete exceeds 40 °C during the curing process unless previous positive experience has shown that special measures are not necessary to avoid micro cracking and/or durability defects: a preheating period shall be applied during which Tmean

Eurocodes are taken as a common reference for design aspects of structural products. The installation of
some structural precast concrete products is dealt with by EN 13670: Execution of concrete structures which
is at the moment under approval as a European Standard. In all countries it can be accompanied by
alternatives for national application and it should not be treated as a European Standard.

Introduction
This standard has been produced as part of the total CEN programme for construction and refers to the
relevant specifications of associated standards EN 206 for concrete and EN 1992 for the design of concrete
structures. Complementary design rules for structural elements are provided where necessary in Annex R and
Annex S.
The design of structural elements should be verified to ensure the fitness of their properties for the particular
application, particular attention being paid to design co-ordination with other parts of the construction.
The evaluation of conformity given in this European Standard refers to the completed precast elements which
are supplied to the market but cover all equipment, material, production process and finished product aspects.
This standard does not cover design rules for the works in which the concrete products are to be used. It is
required, however, to declare values for those parameters which are needed to design the interaction between
the product and the surrounding parts of the works unless design of the product is performed entirely by the
client. Such information can be given in the documentation, see clause 8.

1 Scope
This European Standard identifies the requirements, the basic performance criteria and evaluation of
conformity for unreinforced, reinforced and prestressed precast products made of compact light-, normal- and
3 3 3
heavyweight concrete (oven-dry density of 800-2000 kg/m , 2000-2600 kg/m and more than 2600 kg/m
respectively) with no appreciable amount of entrapped air other than entrained air. It does not cover
prefabricated reinforced components of lightweight aggregate concrete with open structure.
This standard is of general use for all types of precast products and it may be used as a common reference in
specific product standards (see Foreword).
If a specific product standard exists it takes precedence over this standard.
The precast products dealt with in this standard are factory produced for building and civil engineering works,
in series or individually. This standard may also be applied to products manufactured in temporary plants on
site if the production is protected against adverse weather conditions and controlled following clause 6
provisions.

4 Requirements
4.1 Material requirements
4.1.1 General
Only materials with established suitability shall be used.
For a particular material, the establishment of suitability may result from a European Standard which refers
specifically to the use of this material in concrete or in concrete products; in absence of a European Standard
it may also result, under the same conditions, from an ISO standard.
Where this material is not covered by a European or International Standard, or if it deviates from the
requirements of these standards, the establishment of suitability may result from:
the relevant national standards or provisions valid in the place of use of the concrete product which refer
specifically to the use of this material in concrete or in concrete products;
or
an European Technical Approval specifically for the use of this material in concrete or concrete products.
4.1.2 Constituent materials of concrete
4.1.2.1 General
EN 206-1:2000, 5.1 shall apply, including additional provisions in national annexes to EN 206-1.
4.1.2.2 Crushed recycled concrete aggregates
Crushed recycled concrete aggregates, mixed in concrete with other aggregates, shall not adversely alter the
rate of setting and hardening of concrete, nor shall it be detrimental to the durability of the concrete product in
the end use conditions.
In normal weight concrete only crushed recycled aggregates obtained from normal weight concrete shall be
used.
While using recycled concrete aggregates in percentage higher than 10% in weight the validity of hardened
concrete properties derived from compressive concrete strength according to Table 3.1 of EN 1992-1-1 shall
be verified if these properties are used for the calculation of the mechanical resistance of concrete products. If
the validity is not confirmed appropriate type testing shall be performed to determine these properties.
NOTE Recommendations on the use of crushed recycled concrete aggregates with other aggregates are given in the
Annex Q.
4.1.3 Reinforcing steel
Reinforcing steel shall meet the requirements in 3.2 of EN 1992-1-1, including R.3.2.
Other types of reinforcing steel may be used according to relevant national standards or national provisions
valid in the place of use of the product, provided they are fit for the intended purpose and have the required
properties. Suggestions are given in Annex N.

Mechanical inserts and connectors shall:
resist the design actions;
have the necessary ductility;
maintain these properties for the lifetime of the concrete product.
National standards or national provisions valid in the place of use of the product shall be taken into account.
4.2 Production requirements
4.2.1 Concrete production
4.2.1.1 General
For concrete composition, type of cement, use of aggregates, additions and admixtures, and for resistance to
alkali-silica reaction, chloride content, air content and concrete temperature, EN 206-1:2000, 5.2 and 5.3 shall
apply.
For specification of concrete EN 206-1:2000, 6.1 and 6.2 shall apply.
Additional provisions given in National annexes to EN 206-1 shall be taken into account.
4.2.1.2 Placing and compaction of concrete
Concrete shall be placed and compacted so as to retain no appreciable amount of entrapped air other than
entrained air and to avoid detrimental segregation. Within the concrete the reinforcement shall be properly
embedded.
4.2.1.3 Curing (protection against drying out)
The concrete shall be protected during curing so that loss in strength and cracking due to temperature and
shrinkage is avoided. All surfaces of newly cast concrete shall be protected by at least one of the methods
listed in Table 2, unless it can be shown by tests on the finished product or otherwise, that no loss in strength
or surface cracking will occur in the production environment without protection.
The protection shall be maintained until the standard structural strength at the end of curing expressed either
by the degree of hardening or by numerical values as given in Table 1 is reached. For bridge elements, design
working life more than 50 years, or specific to local environmental conditions, other values may be given
following the requirements of their destination as indicated in the design documentation.
The degree of hardening in Table 1 may either be measured by testing a concrete sample or estimated by
calculation using a hardening law based on initial type testing of the maturity concept.
