This European Standard shall be given the status of a nation
19、al standard, either by publication of an identical text or by endorsement, at the latest by November 2012, and conflicting national standards shall be withdrawn at the latest by November 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of pate
20、nt rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12697-24:2004+A1:2007. The main changes with respect to the previous edition are as follows: clarification in the scope that tests using different failure criteria a

22、ed; symbols for the frequency of the sinusoidal load applications and angular speed revised; requirements on age and drying of specimens added in the main text and removed from the individual annexes; limits on interpolation defined; alternative criterion given in a note; requirement for checking (r
23、ather than calibration of) the test equipment added in the main text and removed from the individual annexes; requirement added for the test report to include information on the chosen test method, the used testing equipment, results of the last check on calibration of the testing equipment and the
24、age of the specimen at the time of testing; the tolerance for the displacement of the trapezoidal specimen widened; measurements on the three-point bending test on prismatic specimens started after fewer cycles; note added on rotating the specimen in four-point bending test on prismatic specimens; t
