Abstract

A comparative analysis of national standards of RF and the USA on test methods of low-cycle fatigue (LCF) and high-cycle fatigue (HCF) was carried out in this work. The following national standards were considered: RF standard GOST 25.502–79, last revi-sion in 1985, «Strength analysis and testing in machine building. Methods of mechanical testing of metals. Methods of fatigue testing» and two national standards of the USA – ASTM E466–07 «Standard Practice for Conducting Force Controlled Constant Am-plitude Axial Fatigue Tests of Metallic Materials» and ASTM E606–04 «Standard Prac-tice for Strain-Controlled Fatigue Testing». It was shown that there is no noticeable difference between gage sizes of specimens in the standards mentioned above. As compared with GOST, ASTM E standards specify additional high requirements to specimen surfaces and to loading errors. Thus, National standard of RF GOST 25.502–79, last revision in 1985, has to be essentially modified.
