Schedule 40 NEMA vs. Sch 40 ASTM D1785 pipe in Concrete column

Schedule 40 NEMA vs. Sch 40 ASTM D1785 pipe in Concrete column

Schedule 40 NEMA vs. Sch 40 ASTM D1785 pipe in Concrete column

(OP)
A contractor placed a 3" schedule 40 NEMA pipe in a column for the drainage system. The specs call for ASTM D1785. Will this be a problem? What concerns would the client have with this type of error?

RE: Schedule 40 NEMA vs. Sch 40 ASTM D1785 pipe in Concrete column

Compare the 2 ASTM's to see if the pipes are equal.

RE: Schedule 40 NEMA vs. Sch 40 ASTM D1785 pipe in Concrete column

D1785 is considered a pressure pipe whereas NEMA is a conduit for wiring. Dimensionally they're both the same.
