NEMA RN 1:2005 (R2013) PDF Download

NEMA RN 1:2005 (R2013) standard is concerned with the specifications for PVC coatings applied to galvanized rigid steel conduit and intermediate metal conduit. The standard covers both the continuous PVC exterior coatings, which provide protection against external factors such as moisture and abrasion, as well as the corrosion-resistant interior coatings that safeguard the conduit against internal corrosive elements.

Moreover, the standard addresses the requirements for galvanized steel conduit and galvanized steel intermediate metal conduit itself. It includes specifications for threaded couplings and elbows to which the PVC coatings may be applied. These couplings and elbows play a crucial role in ensuring the durability and integrity of the conduit system.
