European foreword
This document (EN 12390-1:2021) 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 January 2022, and conflicting national standards shall
be withdrawn at the latest by January 2022.
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 12390-1:2012.
The following amendments have been made to the former edition:
— editorial revision;
— increases in the allowable tolerances for flatness of moulds and the dimensions of the specimens
which reflect current industry practice.
This document is one of a series on testing concrete.
EN 12390, Testing hardened concrete, consists of the following parts:
— Part 1: Shape, dimensions and other requirements for specimens and moulds;
— Part 2: Making and curing specimens for strength tests;
— Part 3: Compressive strength of test specimens;
— Part 4: Compressive strength – Specification for testing machines;
— Part 5: Flexural strength of test specimens;
— Part 6: Tensile splitting strength of test specimens;
— Part 7: Density of hardened concrete;
— Part 8: Depth of penetration of water under pressure;
— Part 10: Determination of the carbonation resistance of concrete at atmospheric levels of carbon
dioxide;
— Part 11: Determination of the chloride resistance of concrete, unidirectional diffusion;
— Part 12: Determination of the potential carbonation resistance of concrete: Accelerated carbonation
method;
— Part 13: Determination of secant modulus of elasticity in compression;
— Part 14: Semi-adiabatic method for the determination of heat released by concrete during its hardening
process;
— Part 15: Adiabatic method for the determination of heat released by concrete during its hardening
process;
— Part 16: Determination of shrinkage of concrete;
— Part 17: Determination of creep of concrete in compression;
— Part 18: Determination of the chloride migration coefficient (in preparation).
This document recognizes alternative approaches towards obtaining test specimens of the correct sizes
and shapes. The first is to use moulds whose lives are limited and to measure the specimens to ensure
conformity. The second is to cast specimens in calibrated metal moulds which meet tighter tolerances
than for specimens. The use of calibrated moulds allows relaxation on the requirement for measuring the
specimens.
Annex A gives the application of EN ISO 1101 to measuring the shapes of concrete test specimens and
moulds.
Annex B gives a method to measure the flatness of specimens and moulds.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
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, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United
Kingdom.

4.1 General
For application of EN ISO 1101 to the measurement of concrete test specimens and moulds in respect to
flatness, perpendicularity and straightness, see Annex A.
For each shape of test specimen, cube, cylinder and prism, the nominal size d (Figures 1, 2 and 3) should
be chosen to be at least three and a half times the maximum aggregate size (D according to EN 206)
max
in the concrete.

4.2.2 Designated sizes
Designated sizes may be selected within ± 10 % of the nominal size.
4.2.3 Tolerances
4.2.3.1 Between moulded surfaces the tolerance on the designated size (d) is 1,0 %.
4.2.3.2 Between the top trowelled face and the moulded bottom face the tolerance on the designated
size is 1,5 %.
4.2.3.3 The tolerance on the flatness of the potential load bearing surfaces is 0,000 6d mm
(see Annex B).
4.2.3.4 The tolerance on the perpendicularity of the sides of the cube, with reference to the base, as
cast, is 0,5 mm.
