Precast concrete products - Ribbed floor elements - Part 1 : Essential characteristics
This document identifies the essential characteristics of ribbed floor elements. These elements are precast elements made of reinforced or prestressed normal weight or light weight concrete, used in floors or roofs. They consist of a top and/or bottom slab and one or more (usually two) ribs; transverse ribs may also be present. The concrete does not contain more than 1 % of homogeneously distributed organic material, by mass or by volume (whichever is the most onerous).
When used in roofs, these elements are used in the same way as for a floor, the difference being in the type of covering and the loads they support.
This document specifies procedures for assessment and verification of constancy (AVCP) of performance of characteristics of the ribbed floor elements as well as marking and labelling of these elements.
NOTE This document does not cover load-bearing capacity determined by testing.
Betonfertigteile - Deckenplatten mit Stegen - Teil 1: Wesentliche Merkmale
Dieses Dokument gibt die wesentlichen Merkmale für Deckenplatten mit Stegen an. Diese Betonfertigteile werden aus bewehrtem oder vorgespannten Normalbeton oder Leichtbeton hergestellt und für Boden- und Dachelemente verwendet. Sie bestehen aus einer oberen Platte und/oder einer unteren Platte sowie einem Steg oder mehreren (üblicherweise zwei) Stegen; Querstege können ebenfalls vorhanden sein. Der Beton enthält nicht mehr als 1 % Massenanteil oder Volumenanteil gleichmäßig verteilten organischen Materials (je nachdem was ungünstiger ist).
Bei der Verwendung in Dächern werden diese Bauteile in gleicher Weise verwendet, wie in Decken, wobei der Unterschied in der Art der Deckung (en: covering) und den von ihnen aufgenommenen Lasten besteht.
Dieses Dokument legt Verfahren für die Bewertung und Überprüfung der Leistungsbeständigkeit (AVCP) von Merkmalen von Deckenplatten mit Stegen sowie deren Kennzeichnung und Etikettierung fest.
ANMERKUNG Dieses Dokument deckt Traglastermittlung durch Prüfung nicht ab.
Produits préfabriqués en béton - Eléments de planchers nervurés - Partie 1 : Caractéristiques essentielles
Le présent document identifie les caractéristiques essentielles des éléments de plancher nervurés. Ces éléments sont des éléments préfabriqués en béton de granulats courants ou légers armé ou précontraint, utilisés pour les planchers ou les toitures. Ils sont composés d’une dalle supérieure et/ou inférieure et d’une ou de plusieurs (généralement deux) nervures ; des nervures transversales peuvent également être présentes. Le béton ne contient pas plus de 1 % de matières organiques réparties de façon homogène (en masse ou en volume selon la valeur la plus élevée).
Ces éléments sont utilisés de la même façon pour les toitures que pour un plancher, à la différence du type de revêtement et des charges supportées.
Le présent document spécifie les procédures d’Évaluation et de Vérification de la Constance des Performances (EVCP) des caractéristiques des éléments de plancher nervurés ainsi que de marquage et d’étiquetage de ces éléments.
NOTE Le présent document ne couvre pas la capacité portante déterminée par les essais.

such that the results are applicable to the product in question.
For the purposes of assessment, the products may be grouped into families, where it is considered that
the results for one or more characteristics from any one product within the family are representative for
that same characteristic for all products within that same family.
