NEMA RN 1:2018 PDF Download

The NEMA RN 1:2018 standard outlines specifications for the protection and durability of galvanized rigid steel metal conduit and intermediate metal conduit. The standard covers the application of continuous PVC exterior coatings and corrosion-resistant interior coatings on these conduits.

The PVC exterior coating serves as a protective layer that provides resistance against environmental factors such as moisture, chemicals, and extreme temperatures. This coating helps to prolong the lifespan of the conduit by preventing corrosion and damage. The interior coating is designed to resist corrosion, ensuring the conduit's longevity and ensuring reliable performance.

The standard also encompasses specifications for threaded couplings and elbows that may be used with the coated conduit. It ensures that these components meet the necessary requirements for compatibility and functionality with the PVC-coated galvanized steel conduit.
