A novel accelerated fracture mechanics extrapolation procedure based on cyclic test with cracked round bar CRB)specimens was verified by a correlation of real pipe failure time to simulated failure times at a temperature of 60 8C. The procedure was applied to predict the long-term failure of modern PE 80 and PE 100 pipes 23 8C. Moreover, the used stress intensity factor concept also allows to consider the impact of arbitrary additional loading situations like soil loads or point loads and to assess pipe lifetime under complex loading situations.
