Inter-laboratory comparison of fatigue test with evaluation of the participating laboratories calculations of measurement uncertainty (NT TR 533)

NT TR 533

  • In this paper a fatigue testing inter-laboratory comparison is presented. Six Nordic laboratories performed fatigue tests on steel specimens. The specimens were tested with different stress levels (460 MPa, 430 MPa and 400 MPa) and with the load ratio R=Smin/Smax =0.1. On each level four specimens were tested. The participating laboratories reported the results together with measurement uncertainty.
