NSF international provides testing and certification of PVC and HDPE electrical conduit pipe, fittings, bends and telecommunications duct to UL and NEMA standards. Our Electrical Conduit Certification Program provides listing and labeling on electrical conduit to ANSI/UL 651 Schedule 40 and 80 Rigid PVC Conduit and Fittings as well as the Canadian counterparts CSA-C22.2 No. 211.1 and No. 211.2.

Acceptance of NSF’s listed and labeled electrical products is widespread and based on our designation as an OSHA Nationally Recognized Testing Laboratory (NRTL) for electrical safety and our accreditation by the Standards Council of Canada (SCC).

Conduit pipe, fittings and bends undergo an extensive evaluation process including product testing, materials testing and formulation review, facility inspection and annual review.
