6、ests using different failure criteria are not comparable; b) the definition of conventional criteria of fatigue for constant force has been deleted, leaving just constant displacement; c) the definitions of the average and standard deviations of the fatigue life of a series of specimens for the two-

8、of interpolation have been defined; g) an alternative criterion is given in a note; h) the requirement for checking (rather than calibration of) the test equipment has been moved from the annexes to the main text; i) a requirement has been added for the test report to include information on the test
9、 method, testing equipment, checking of the testing equipment and the age of the specimen at the time of testing; j) the tolerance for the displacement of the trapezoidal specimen has been extended; k) the measurements in the three-point bending test on prismatic specimens now start after fewer cycl
10、es; l) a note has been added on rotating the specimen in the four-point bending test on prismatic specimens; m) the optional requirement for choosing a frequency spectrum of initial complex (stiffness) moduli has been removed from the four-point bending test on prismatic specimens; n) the principle,
11、 equipment, procedure and calculations of the indirect tensile test on cylindrical specimens have been revised.

30、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 age of the specimen at the time of testing; the tolerance f
31、or 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; the optional requirement for choosing frequency spectrum of
32、initial complex (stiffness) moduli removed from the four-point bending test on prismatic specimens; the principle, equipment, procedure and calculations of the indirect tensile test on cylindrical specimens revised.
