Fatigue performance

According to BS 4449:2005-A3:2016 Fatigue test is carried out on full section bars using a sinuso dal tensile load as follows:

	Diameter, mm	Max. stress,mpa	Min. stress,mpa	No. of cycle
>16	250	50	5.0 million
2	231	46	5.0 million
25	212	42	5.0 million
32	200	40	5.0 million
40	187.5	37.5	5.0 million
50	187.5	375	5.0 million

All tests are required to survive for 5 million stress cycles under these loading conditions. The procedure is carried out at room temperature with a frequency of up to 200Hz.

The test is continued until 5 million stress cycles have been reached or until the fracture of the test sample.
