1 Scope This British Standard describes a method of cyclically loading a metallic specimen under strain control between set strain limits to determine its fatigue resistance. The fatigue resistance is measured in terms of cycles to failure as a function of the applied strain range and the associated variations in stress range , mean stress and plastic strain range . The method is restricted to uniaxially loaded parallel section specimens tested in air at ambient temperature and to metals where time-dependent deformation can be ignored. The method is applicable to both high-and low- cycle fatigue tests.
NOTE 1 Advice on the generation of data sets from individual specimen results determined using this method is given in Annex A.
NOTE 2 Users should assure themselves that the test conditions used and the specimen orientation are relevant to their application.
