Electrical Conduit

As an additional service for its plastic piping manufacturer clients, NSF provides electrical safety testing of PVC and HDPE electrical conduit and telecommunications duct. This program was founded in 2001 to help clients save time and resources by bundling both their health effects and electrical conduit testing. These services, however, are available to any client, existing or new, regardless of their need for health effects testing.

NSF performs electrical conduit testing entirely at its Ann Arbor, Michigan headquarters. The facility has been listed in the Federal Register as an OSHA Nationally Recognized Testing Laboratory (NRTL) for electrical safety and is also accredited by the Standards Council of Canada (SCC) to perform certifications to CSA standards.
