Steel -- Torsional stress fatigue testing
This standard has been revised by ISO 1352:2011
The tests are carried out at room temperature, in air, by applying to the test piece a pure couple about its longitudinal axid. Test piece diameters are between 5 mm and 12,5 mm. The proparation, form and testing of test pieces of circular cross-section are specified. Does not specify component testing and high strain torsional fatigue tests, which lead to failure in a few thousand cycles.
A standard is reviewed every 5 years
