In 2007, AWWA C900 PVC Pressure Standards were changed to reflect experience with PVC pipe products in municipal applications for over 30 years, current research into PVC performance and harmonizing various PVC pressure pipe standards. This article explains the new pressure classes of DR14-305 psi, DR18-235 psi and DR25-165 psi PVC pipe products. Pipe wall thicknesses and dimensions stayed the same with this change.
An article entitled "PVC Pressure Pipe Endures Over Ten Million Cycles" discusses research on PVC performance under cyclic loading.

Molecularly Oriented PVC Pipe — PVCO: light-weight, thinner-walled alternative with the same pressure capacity as thicker-walled PVC pipe.
Guide for PVC sewer force mains uses recently developed method for cyclic-fatigue design.
Recent hydraulic research on new and in-service PVC pipe has confirmed that industry-recommended flow coefficients are conservative for design of pressure and non-pressure pipes.
