For the first time since 2000, NEMA releases standard on polyethylene conduit

NEMA recently released a new standard, TC 7-2005, “Smooth-Wall Coilable Electrical Polyethylene Conduit.” The standard provides guidelines for concrete-encased or direct burial applications of electrical high-density polyethylene (HDPE) conduit: EPEC-A, EPEC-B, EPEC-40, and EPEC-80. The Plastic Pipe Institute assisted with the coordination of NEMA TC-7 with ASTM F2160, “Solid Wall HDPE Conduit Based on Controlled Outside Diameter.”

TC 7-2005 is available at the NEMA Web site for $47 or by contacting Global Engineering Documents at (800) 854-7179.
