Testing concrete in structures - Part 3: Determination of pull-out force

This document specifies a method for the determination of the pull-out force of hardened concrete using a cast-in disc insert and rod, or a similar device installed afterwards by drilling into the hardened concrete.
NOTE   The test method is not intended as an alternative for the determination of the compressive strength of concrete, but with suitable correlations it can provide an estimate of in situ strength.

Prüfung von Beton in Bauwerken - Teil 3: Bestimmung der Ausziehkraft

1.1   Diese Norm ein Verfahren zur Bestimmung der Ausziehkraft von Festbeton mit einer Einlage, die in den Frischbeton eingesetzt wird oder einer ähnlichen Einlage fest, die nachträglich in den Festbeton eingebohrt wird.
ANMERKUNG   Das Prüfverfahren gilt nicht als Alternative für die Bestimmung der Druckfestigkeit von Beton; bei geeigneten Korrelationen kann es jedoch zu einer Schätzung der Festigkeit im Bauwerk führen.

Essais pour béton dans les structures - Partie 3: Détermination de la force d'arrachement

La présente Norme européenne spécifie une méthode permettant de déterminer la force d'arrachement du béton durci à l'aide d'un insert coulé dans le béton, constitué d'un disque et d'une tige, ou d'une insertion similaire placée ultérieurement par forage à l'intérieur du béton durci.
NOTE   Cette méthode d'essai ne peut pas se substituer aux essais de détermination de la résistance du béton à la compression ; cependant, elle peut fournir une estimation de la résistance in situ du béton si des corrélations fiables sont établies.

This European Standard was approved by CEN on 4 September 2003.
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national
standards may be obtained on application to the Central Secretariat or to any CEN member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation
under the responsibility of a CEN member into its own language and notified to the Central Secretariat has the same status as the official
versions.

Foreword
This document (EN 12504-3:2005) 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 September 2005, and conflicting national standards shall be withdrawn at the
latest by September 2005.
This European Standard is based on ISO/DIS 8046 "Concrete hardened — Determination of pull-out strength".
This standard is one of a series of methods for testing concrete in structures.
A draft standard was submitted in 1996 to CEN enquiry as prEN 12399. It was one of a series of individually
numbered test methods for fresh or hardened concrete. For convenience it has now been decided to combine
these separate draft standards into three new standards with separate Parts for each method, as follows:
 Testing fresh concrete (EN 12350)
 Testing hardened concrete (EN 12390)
 Testing concrete in structures (EN 12504)
This series EN 12504 includes the following Parts where the brackets give the numbers under which particular test
methods were submitted to CEN enquiry:
EN 12504 Testing concrete in structures —
 Part 1: Cored specimens — Taking, examining and testing in compression (former prEN 12504:1996)
 Part 2: Non-destructive testing — Determination of rebound number (former prEN 12398:1996)
 Part 3: Determination of pull-out force (former prEN 12399:1996)
 Part 4: Determination of ultrasonic pulse velocity (former prEN 12396:1998)
The Annex A of this standard is informative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark,
Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
Introduction
A range of different methods of measuring pull-out force are available. ISO/DIS 8046 only refers to embedded
inserts. This document has been extended to include similar inserts which can be inserted into the hardened
concrete and expanded, but which do not create sideways stresses in the concrete.
There are methods which rely on gluing or on the production of sideways stresses to secure an insert, but it is not
yet clear whether these give the same results as the methods included in this part.
The measurement can be used to estimate in-situ strength, to determine when post tensioning can proceed, when
forms and props can be removed, when winter protection and curing can be terminated, or for comparative testing.
