Atkore’s PVC coated galvanized rigid steel conduit has earned ETL verification while also meeting Underwriters Laboratory 6 Safety Standards. ETL verification and UL 6 safety listing validate the adhesion of the conduit’s PVC coating and ensure long-term system protection in the harshest environments including bridges, tunnels, wastewater treatment, petrochemical and mining.
Intertek’s ETL SEMKO PVC001 tests subject conduit systems to extreme heat and humidity, two proven environmental factors that reduce the effectiveness of PVC coating adhesion and accelerate corrosion. With more than 200 hours of exposure to liquid at a temperature higher than 90°C +/-5°C and 95 percent relative humidity, the conduit systems’ adhesion and internal/external coatings are tested to confirm that the bond of the PVC coating to the steel substrate is not only suitable but made to last through extreme conditions.
The UL 6 listing entails a series of four tests simulating real-world weathering of PVC coated conduit. A protective coating of zinc must be evenly applied to the exterior surface of the galvanized rigid conduit, adhering firmly without any blistering or defects. Although PVC coating does not naturally bond to zinc, Atkore’s bonding agent ensures a secure seal between the zinc layer and PVC coating, eliminating chances for corrosion.
“We take pride in supplying the rigid-conduit market with a solution that is ETL verified for performance and UL listed for safety,” said Mike Lang, senior product manager of corrosion resistant conduit at Atkore. “Whether you’re a contractor, consultant or design engineer, now there is a choice when it comes to selecting ETL-verified PVC coated conduit.”
Atkore’s ETL-verified PVC coated conduit is available through a network of stocking distributors for its Calbond or Allied Tube & Conduit brands. For more information, visit https://www.calbond.com/pvc-coated-conduit/.
