oder für die Bohrstellen.
ANMERKUNG 2 Diese Europäische Norm enthält keine Verfahren für die Auswertung der Ergebnisse der Festigkeit von
Bohrkernen.

Essais pour béton dans les structures - Partie 1: Carottes - Prélèvement, examen et essais en compression
La présente Norme européenne spécifie une méthode permettant d'effectuer le prélèvement de carottes de
béton durci, leur examen, leur préparation avant l'essai et la détermination de leur résistance à la
compression.
NOTE 1 Elle ne définit pas de lignes directrices quant à la pertinence de l’extraction de carottes ni quant à la position
des carottages dans l’ouvrage.
NOTE 2 Elle ne préconise pas de méthode d’interprétation des résultats des essais de résistance effectués sur les

EN 12504-1:2009 (E) 3 Foreword This document (EN 12504-1:2009) has been prepared by Technical Committee CEN/TC 104 “Concrete and related products”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August 2009, and conflicting national standards shall be withdrawn at the latest by August 2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12504-1:2000. It is recognized good practice to include measurement of density prior to the determination of compressive strength, as a check on compaction of the concrete. In drafting the standard consideration has been given to the results of the research programme, part funded by the EC under the Measurement and Testing Programme, contract MAT1-CT94-0043. The standard includes simple guidance on the process of taking cores, but does not consider a sampling plan. It also provides procedures for visual examination and compressive strength testing, but not the interpretation of the results. This standard is one of a series concerned with testing concrete. This series EN 12504 includes the following parts: EN 12504 Testing concrete in structures Part 1: Cored specimens - Taking, examining and testing in compression;
Part 2: Non-destructive testing - Determination of rebound number; Part 3: Determination of pull-out force; Part 4: Determination of ultrasonic pulse velocity. The following amendments have been made to the 2000-03 edition of this standard: editorial revision compressive strength to be expressed to the nearest 0,1 MPa (N/mm²) instead of 0,5 MPa (N/mm²) According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

This document is currently submitted to the Unique Acceptance Procedure.
This document will supersede EN 12504-1:2000.
It is recognized good practice to include measurement of density prior to the determination of compressive
strength, as a check on compaction of the concrete.
In drafting the standard consideration has been given to the results of the research programme, part funded
by the EC under the Measurement and Testing Programme, contract MAT1-CT94-0043.
The standard includes simple guidance on the process of taking cores, but does not consider a sampling plan.
It also provides procedures for visual examination and compressive strength testing, but not the interpretation
of the results.
This standard is one of a series concerned with testing concrete.
This series EN 12504 includes the following parts:
EN 12504 Testing concrete in structures
Part 1: Cored specimens - Taking, examining and testing in compression;
Part 2: Non-destructive testing - Determination of rebound number;
Part 3: Determination of pull-out force;
Part 4: Determination of ultrasonic pulse velocity.
