Nema Releases Revised Polyethylene Conduit Standard
ROSSLYN, Va., August 24, 2005"oNEMA, the National Electrical Manufacturers Association, has released TC 7-2005, Smooth-Wall Coilable Electrical Polyethylene Conduit, revised for the first time since 2000. This standard covers the following types of electrical high-density polyethylene (HDPE) conduit designed for applications below ground, either concrete encased applications or direct burial: EPEC-A, EPEC-B, EPEC-40, and EPEC-80.
Members of the Plastic Pipe Institute (PPI) worked with NEMA members to harmonize NEMA TC-7¡Xfor electrical, communication, and signaling applications¡Xwith ASTM F2160, Solid Wall High Density Polyethylene (HDPE) Conduit Based on Controlled Outside Diameter.
¡§NEMA TC-7 is used by utility and communication companies when specifying HDPE raceways,¡¨ says David Kendall, director of industry affairs for Carlon, Lamson & Sessions, and chairman of NEMA¡¦s Polymer Raceway Section. ¡§This standard is vital because it includes technical information supplied to the members by users and inspectors to ensure that the HDPE Raceway is safe and durable.¡¨
TC 7-2005 may be purchased for $47.00 by visiting www.nema.org/stds/tc7.cfm, or by contacting Global Engineering Documents at (800) 854-7179 (within the U.S.), (303) 397-7956 (international), or (303) 397-2740 (fax).
NEMA is the leading trade association in the United States representing the interests of electroindustry manufacturers. Founded in 1926 and headquartered near Washington, D.C., its 400 member companies manufacture products used in the generation, transmission and distribution, control, and end-use of electricity. Domestic shipments of electrical products within the NEMA scope exceed $100 billion.
