scope:

This standard covers several wall types of high-density polyethylene (HDPE) conduit for use in providing a protective raceway for electrical cables or communication cables buried underground or concrete encased.

Note: Typical applications for HDPE conduit include power distribution, site lighting, signal and control and Supervisory Control and Data Acquisition (SCADA).

Wall types include the following:

EPEC-40 HDPE. This type represents the nominal dimensions for Schedule 40 conduit consistent with ASTM F2160, ASTM D3485 and UL 651B or UL 1990 for Cable-in-Conduit (CIC).

EPEC-80 HDPE. This type represents the nominal dimensions for Schedule 80 conduit consistent with ASTM F2160, ASTM D3485 and UL 651B or UL 1990 for CIC.

EPEC-11 HDPE. This type represents the nominal dimensions for SDR 11 conduit consistent with ASTM F2160, ASTM D3485 and is not currently covered by UL.

EPEC-13.5 HDPE. This type represents the nominal dimensions for DR 13.5 conduit consistent with ASTM F2160, ASTM D3485 and UL 651A or UL 1990 for CIC.

EPEC-15.5 HDPE. This type represents the nominal dimensions for DR 15.5 conduit consistent with ASTM F2160, ASTM D3485 and UL 651A or UL 1990 for CIC.

EPEC-17- HDPE This type represents the nominal dimensions for DR 17 conduit consistent with ASTM D3035, and UL 651A or UL1990 for CIC.

Note: The values stated in U.S. customary units are to be regarded as the standard.
