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.
