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text or by endorsement, at the latest by August 2009, and conflicting national standards shall be withdrawn at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 detem ination 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/mmr)instead of 0,5 MPa (N/mmr)
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, Gemany, Greece, Hungary, lceland, Ireland, ltaly,
Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,Poland,Portugal,Romania,Slovakia,
Slovenia, Spain, Sweden, Switzerland and the United Kingdom.
