Polycarbonate parts for railway track fastenings fractured when they are continuously subjected to the stress in the condition of contacting with water-proof oil components. In this paper, the cause of the fracture has been studied. For the analysis, New C-type Creep Method established by the author is used taking S.S.C. Creep Index as a measure. The reason why polycarbonate fractured in the railway track was synergistic effect by the actions among DMP, glycol and the corrosion inhibitor (ether type) for the polymer, combined with the interaction between the stress and these reagents.
