Ok, so if that is the case, where do you locate your transition? Typically we see that as happening at approx. 1'-0 AFF.
For PVC systems it is often customary to use a Ductile fitting at the base of the riser and come up through the slab with ductile, flange at 12" aff and then transition to steel. Craig L.

The variables of concern and related tests are based on the use and environment that the pipe is exposed to. Once you pass the plane of the floor, wouldn't a different set of concerns apply? Bottom line, it is Above Ground pipe and must be listed within that category.
