CTS CPVC ASTM D 2846 Dimensions and
Tolerances
FlowGuard Gold CTS CPVC pipe and fittings used in potable water systems are manufactured to the dimensions and specifica-
tions shown in ASTM D 2846. This product is tan in color, and the pipe has the same outside diameter as copper tubing. Pipe up
through nominal 2” size is manufactured to a standard dimension ratio (SDR) of 11. The standard dimension ratio represents
the ratio of the pipe O.D. to the pipe wall thickness. Consequently, all of the SDR 11 CPVC sizes have the same pressure rating.
