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.
