PVC Pipe and Fittings Materials – Testing Requirements

Posted By John Houle on Dec 6, 2017

In my three decades in the PVC pipe industry, I have noticed that many design engineers and utility personnel are surprised when they learn about the testing regimen that is followed by PVC pipe manufacturers. In addition to tests performed on finished products, there are requirements for the PVC materials themselves.


In fact, the PVC pipe industry follows a rigorous process to assure that its PVC materials meet the requirements of the PVC pipe-product standards. Before a PVC material can be used for pipe or fittings, it must pass a series of qualification tests. If the piping products are intended for pressure or drinking-water applications, additional tests are required to further qualify the materials.
