Re: PVC Supply piping
Not to my knowledge.
It was 'not looked at closely enough' in many areas as the codes used to use one chart for both water service pipe and water distribution pipe, and one had to go through the additional step of looking at the referenced sections to determine what was allowed or not.
For example, the old Standard Plumbing code referenced Section P608, which only required "The minimum working pressure of plastic piping installed outside of the foundation walls shall be 160 psi (1103 kPa) at 73ºF (23ºC), with permanent identification markings." - which equals PVC, whereas water distribution piping referenced P611, which required "P611.1.1 Minimum working pressure for plastic hot and cold piping material shall be 100 psi (689.5 kPa) at 180ºF (82ºC)." - which equals CPVC.
If all you did was look at the table, PVC was listed in the table as suitable for use - you also needed to verify its 'suitability for WHAT use', which many did not think of doing.
