PVC Technical Information
Because of its versatility and good balance of properties, PVC has found applications in many different markets. By far the largest of these is the building and construction market, with pipe being the largest single application. The PVC Technical Committee of PIPA provides on this page test methods and technical reports on PVC pipeline systems which can be read on the screen or printed for future reference.

This technical note on temperature derating is based on ISO4422 but with these alterations:
Also provided is a table with both the numerical derating factors tabulated and a simple graph of derating factor versus temperature.
This technical note on life expectancy for plastics pipes dismisses the myth that plastics pipe systems have a life expectancy of 50 years. In reality, such systems can reasonably be expected to last 100 years or more. Everything is pointing to at least 100 years practical service life for today's buried sewer pipes made of high quality virgin PVC-U and PE resins, on condition that the pipes are used in accordance with the prevalent national standard installation instructions.
This technical note on PVC pressure pipes operating at low temperatures tells us that although at temperatures above 20°C the strength is reduced and at temperature below 20°C the strength increases, the decrease in the impact resistance of PVC pipes at low temperatures is only a concern for those installations where impact might occur in service.
This technical note is based on the low pressure air test nominated in the WSAA Sewerage Code of Australia (WSA 02-2002 V2.3). The purpose of the test is to identify leaks in non pressure pipe installations.
