EN 12390-5:2009 (E) 3 Foreword This document (EN 12390-5:2009) 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of an identical text or by endorsement, at the latest by August 2009, and conflicting national standards shall be withdrawn at the latest by August 2009.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 12390-5:2000. It is recognized good practice to include measurement of density prior to the determination of flexural strength, as a check on compaction of the concrete. The two-point method of loading has been taken as the reference method, but the use of centre-point loading has been included as a normative annex. An inter-comparison of the two-point and the centre-point methods has been made as part of a test programme, part-funded by the EC under the Measurement and Testing Programme, contract MAT I-CT-94-CO43. The centre-point method gave results which were consistently 13 % higher than those from the two-point method. This standard is one of a series concerned with testing concrete. The series EN 12390 includes the following parts: EN 12390 Testing hardened concrete –
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.
The following amendments have been made to the 2000-10 edition of this standard: editorial revision selected loading rate to be applied after the initial (not exceeding approx 20% of the anticipated failure load) 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, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, SIST EN 12390-5:2009
