European foreword
This document (EN 12504-1:2019) has been prepared by Technical Committee CEN/TC 104 “Concrete
and related products”, the secretariat of which is held by SN.
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 December 2019, and conflicting national standards
shall be withdrawn at the latest by December 2019.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 12504-1:2009.
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 on testing concrete.
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.
This edition includes the following significant technical changes with respect to EN 12504-1:2009:
a) editorial revisions;
b) measurement of core dimensions;
c) core samples to be tested in an in situ or wet conditions;
d) procedures for preparation of specimens prior to testing.
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, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland,
Turkey and the United Kingdom.
