In this paper, results of short and long time internal pressure tests on a number of PVC pipe samples are pre- sented. Modes of failure of the pipe specimens consisting of ductile rupturing and brittle fracturing have been do- cumented. The results of long time tests have been extra- polated by means of Standard Extrapolation Method (SEM) to 50 years of PVC pipe performance. Presented are also the results of rated loading tests and their comparisons with constant pressure tests. Based on a more refined theoretical modeling of the pipe samples, it has been concluded that the currently used relation should undergo a proposed modification.
