Testing concrete in structures - Part 2: Non-destructive testing - Determination of rebound number

This European Standard specifies a method for determining the rebound number of an area of hardened concrete using a spring-driven hammer.

Prüfung von Beton in Bauwerken - Teil 2: Zerstörungsfreie Prüfung - Bestimmung der Rückprallzahl

Diese Norm legt ein Verfahren zur Bestimmung der Rückprallzahl einer Fläche aus Festbeton bei Prüfung mit einem Federhammer fest. ANMERKUNG 1 Die nach diesem Verfahren bestimmte Rückprallzahl kann für den Nachweis der Gleichmäßigkeit von Ortbeton sowie für die Darstellung von Bereichen oder Flächen geringer Güte oder für beschädigten Beton in Bauwerken verwendet werden. ANMERKUNG 2 Das Prüfverfahren ist nicht als Alternative für die Bestimmung der Druckfestigkeit von Beton (EN 12390-3) vorgesehen; mit Hilfe geeigneter Korrelationen kann es jedoch einen Schätzwert für die Druckfestigkeit von Ortbeton liefern. Zur Bewertung der Druckfestigkeit von Ortbeton siehe EN 13791. ANMERKUNG 3 Der Hammer darf zur vergleichenden Prüfung eingesetzt werden, mit einem Beton bekannter Festigkeit oder mit einem Beton verglichen werden, der nachweislich von einem definierten Betonvolumen stammt, für dessen Grundgesamtheit die Übereinstimmung mit einer bestimmten Festigkeitsklasse nachgewiesen wurde.

Essais pour béton dans les structures - Partie 2: Essais non destructifs - Détermination de l'indice de rebondissement

La présente Norme européenne spécifie une méthode de détermination de l'indice de rebondissement d'une
surface de béton durci, à l'aide d'un marteau projeté par ressort.
NOTE 1 L'indice de rebondissement déterminé à l'aide de la présente méthode peut être utilisé pour évaluer
l'homogénéité du béton in situ, pour délimiter, dans des structures, des zones ou des surfaces de béton de qualité
médiocre ou détériorées.
NOTE 2 La présente méthode d'essai n'est pas destinée à être une autre méthode de détermination de la résistance à
la compression du béton (EN 12390-3), mais avec une corrélation fiable, elle peut fournir une estimation de la résistance à
la compression du béton in situ. Pour l'évaluation de la résistance à la compression in situ, voir l'EN 13791.
NOTE 3 Le marteau peut être utilisé pour des essais comparatifs, sur du béton dont la résistance est connue ou sur du
béton pour lequel on a démontré qu'il provient d'un volume défini de béton dont on a vérifié que l'ensemble est conforme à
une classe de résistance particulière.

EN 12504-2:2012 (E) 3 Foreword This document (EN 12504-2:2012) 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 March 2013, and conflicting national standards shall be withdrawn at the latest by March 2013. 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 12504-2:2001. This document is based on the International Standard ISO 1920-7, Testing of concrete – Part 7: Non-destructive tests on hardened concrete, and reference has been made to ASTM C805, Standard Test Method for Rebound number of hardened concrete. This document has been framed around the use of a Type N, spring driven steel hammer, originally designed by Schmidt. This European Standard is one of a series of test methods for concrete. The series EN 12504 "Testing concrete in structures" consists of the following parts:  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 main changes with respect to the previous edition are listed below: a) editorial revision; b) clarification to the procedure for carrying out the test and indicates the required specification of the equipment to be used; c) the option of using an electronic measuring device as well as the mechanical version. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania
