(Main)Common rules for precast concrete products
Common rules for precast concrete products
This European Standard specifies the terminology, requirements, basic performance criteria, test methods and evaluation of conformity that will be referred to by specific product standards unless they are not appropriate. 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 products.
If a specific precast concrete product standard exists it takes precedence over this standard.
The precast products dealt with in this standard are factory produced for buildings 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 information about :
- the choice of partial safety factors defined by the Eurocode;
- the rules for applying calculations to high strength concrete ;
- the definition of requirements for prestressed concrete products.
This standard applies to concrete compacted so as to retain no appreciable amount of entrapped air other than entrained air and with a dry density equal to or greater than 800 kg/m3.
Allgemeine Regeln für Betonfertigteile
Anwendungsbereich
Diese Europäische Norm legt Begriffe, Anforderungen, grundlegende Leistungskriterien, Prüfverfahren
sowie Verfahren zur Konformitätsbewertung fest, auf die in speziellen Produktnormen Bezug zu nehmen
ist, sofern diese geeignet sind. Diese Norm kann auch für spezielle Produkte, für die es keine Produkt-
norm gibt, verwendet werden. Nicht alle Anforderungen dieser Norm (Abschnitt 4) sind für sämtliche
Betonfertigteile zutreffend.
Wenn eine spezielle Produktnorm für ein Betonfertigteil vorliegt, hat sie Vorrang gegenüber dieser Norm.
Die in der vorliegenden Norm behandelten Betonfertigteile sind werkmäßig hergestellte Teile für den
Hoch- und Ingenieurbau. Diese Norm kann auch für Produkte angewendet werden, die in temporären
Anlagen auf der Baustelle hergestellt werden, wenn die Herstellung gegen ungünstige Witterungs-
einflüsse geschützt ist und nach den Festlegungen in Abschnitt 6 kontrolliert wird.
Die Berechnung und Bemessung von Betonfertigteilen gehören nicht zum Anwendungsbereich der vor-
liegenden Norm. Es werden jedoch Informationen gegeben zu:
- Auswahl der Teilsicherheitsbeiwerte, die im Eurocode festgelegt sind;
- Regeln für die Durchführung von Berechnungen für hochfesten Beton;
- Festlegung der Anforderungen für vorgespannte Betonfertigteile.
Diese Norm gilt für Beton, der so verdichtet wurde, dass er außer den Luftporen keine nennenswerten
Lufteinschlüsse und eine Trockenrohdichte von U 800 kg=m 3 aufweist.

Regles communes pour les produits préfabriqués en béton
La présente Norme indique la terminologie, les prescriptions, les criteres relatifs aux performances de base, les méthodes de vérification et d'évaluation de la conformité qui doivent servir aux normes de produits spécifiques sauf si elles ne sont pas appropriées. Elle peut aussi etre utilisée pour spécifier des produits pour lesquels il n'existe pas de norme. Les prescriptions (chapitre 4) de la norme ne sont pas toutes applicables a l'ensemble des produits préfabriqués en béton.
Si une norme spécifique pour un produit préfabriqué en béton existe déja, elle a priorité sur la présente norme.
Les produits préfabriqués considérés dans la présente norme sont fabriqués en usine et destinés a des bâtiments ou des ouvrages de génie civil. La présente norme peut également etre appliquée a des éléments fabriqués dans des usines temporaires sur un chantier, si la fabrication est protégée contre les conditions environnementales néfastes et contrôlée suivant les exigences du chapitre 6.
L'analyse et la conception de produits préfabriqués en béton ne sont pas inclus dans cette norme mais elle donne des informations sur :
- le choix de coefficients de sécurité partiels définis par l'Eurocode ;
- les regles a appliquer pour les calculs concernant le béton a haute résistance ;
- la définition de prescriptions pour les produits en béton précontraint.
La présente norme s'applique au béton de densité seche égale ou supérieure a 800 kg/m3, compacté de maniere a ne pas retenir une quantité significative d'air autre que l'air occlus.

EN 13369:2001 (E)4ForewordThis European Standard has been prepared by Technical Committee CEN/TC 229 "Precast concrete products", thesecretariat of which is held by AFNOR.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by February 2002, and conflicting national standards shall be withdrawn at the latestby February 2002.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden,Switzerland and the United Kingdom.IntroductionThis standard is intended to outline the general common requirements applicable to a large number of precastconcrete products manufactured in a factory environment. It will act as a reference standard for other standards toenable a more consistent approach to standardisation in the field of precast concrete products and to reduce thevariations brought about by a large number of standards being 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 theyare required.This standard has been produced as part of the total CEN programme for construction and is in phase withassociated standards EN 206-1 for concrete and ENV 1992 for the design of concrete structures. As it is not amandated standard it cannot lead to CE marking.The design of structural products should be verified to ensure the fitness of their properties for the particularapplication, particular attention being paid to design co-ordination with other parts of the construction.SIST EN 13369:2002
