This paper presents experimental data for three Japanese polyolefin pipe grades exposed to chlorinated water. The chlorine concentrations used are 0.5, 1 and 3 ppm. Results are presented in creep rupture diagrams. The results are compared with hydrostatic pressure tests using 0 ppm of chlorine. Extrapolations using multiple linear regression are being demonstrated. Discussions about the failure mechanisms are presented illustrated by fractography and DSC analyses.
