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 stressrange, meanstress 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.
