Article 352 has been renamed in the 2008 NEC because there is more than one type of rigid nonmetallic conduit. (See Article 353, and new to the 2008 Article 355)
The new title of Article 352 is "Rigid Polyvinyl Chloride Conduit: Type PVC."

Not mentioned as a specific conduit material, but it would fall under 344 RMC - Rigid Metal Conduit.
Several RMC base types are mentioned, but the PVC would fall under an "approved supplementary corrosion protection" method.
From 2008 NEC, 344 - RMC:
344.10 Uses Permitted.
(A) Atmospheric Conditions and Occupancies.
(1) Galvanized Steel and Stainless Steel RMC. Galvanized steel and stainless steel RMC shall be permitted under all atmospheric conditions and occupancies. (2) Red Brass RMC. Red brass RMC shall be permitted to be installed for direct burial and swimming pool applications.
(3) Aluminum RMC. Aluminum RMC shall be permitted to be installed where judged suitable for the environment. Rigid aluminum conduit encased in concrete or in direct contact with the earth shall be provided with approved supplementary corrosion protection.
(4) Ferrous Raceways and Fittings. Ferrous raceways and fittings protected from corrosion solely by enamel shall be permitted only indoors and in occupancies not subject to severe corrosive influences.
(B) Corrosive Environments.
(1) Galvanized Steel, Stainless Steel, and Red Brass RMC, Elbows, Couplings, and Fittings. Galvanized steel, stainless steel, and red brass RMC elbows, couplings, and fittings shall be permitted to be installed in concrete, in direct contact with the earth, or in areas subject to severe corrosive influences where protected by corrosion protection and judged suitable for the condition.
(2) Supplementary Protection of Aluminum RMC. Aluminum RMC shall be provided with approved supplementary corrosion protection where encased in concrete or in direct contact with the earth.

How about 344.2?
"RMC is generally made of steel with protective coatings..."

PVC coated Rigid Metal Conduit is regulated under Article 344.
