16、 This document (EN 12390-1:2012) 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

17、 latest by March 2013, and conflicting national standards shall be withdrawn at the latest by March 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights other than those identified above. CEN and/or CENELEC shall not be held respo

18、nsible for identifying any or all such patent rights. This document supersedes EN 12390-1:2000. This standard 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

19、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;

20、 Part 8: Depth of penetration of water under pressure; Part 9: Freeze-thaw resistance Scaling (technical specification); Part 10: Determination of the relative carbonation resistance of concrete (technical specification); Part 11: Determination of the chloride resistance of concrete, unidirectional

21、diffusion (technical specification). The following amendments have been made to the former edition: editorial revision; increases in the allowable tolerances for the dimensions of the specimens which reflect current industry practice. This standard recognises alternative approaches towards obtaining

22、 test specimens of the correct sizes and shapes. The first is to use moulds whose life is 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 relaxa

23、tion on the requirement for measuring the specimens. DIN EN 12390-1:2012-12 EN 12390-1:2012 (E) 4 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. According to the CEN/C

24、ENELEC Internal Regulations, the national standards organizations 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,

25、 Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. DIN EN 12390-1:2012-12 EN 12390-1:2012 (E) 5 1 Scope This European Standard specifies the shape, dimensions a

26、nd tolerances of cast concrete test specimens in the form of cubes, cylinders and prisms, and of the moulds required to produce them. NOTE The tolerances specified in this European Standard are based on the needs of strength testing, but they can be applicable to tests for other properties. 2 Normat
