Our certification program for protective coatings covers test procedures and performance criteria for the evaluation of organic and metallic corrosion protection coatings of steel enclosures. Protective coatings that meet our requirements are certified as UL Recognized Components and are published in UL’s Product iQ Database.
The general use of these coatings is for protection of the metal against atmospheric corrosion when applied to surfaces of steel enclosures, typically in outdoor-use environments. Depending on a product’s intended usage, we might conduct a salt-spray (fog) test, moist carbon dioxide-sulfur dioxide-air test and/or a light and water test for clear coatings.
Traceability of protective coatings
We also offer a corrosion protection coating traceability program intended to eliminate the uncertainty of the protective coating identity and application process in an end-use product. The program provides traceability along the supply chain and verification of the correct application process for UL Recognized component organic coating systems.
DTHW covers metallic coatings — zinc, zinc-iron, aluminum-zinc, zinc-aluminum-magnesium and zinc-nickel alloy — and the substrates to which they are applied. Metallic coatings are intended to be applied to exterior and interior surfaces of steel enclosures of outdoor-use electrical equipment to protect the metal against atmospheric corrosion.
Products and Standards
Protective coatings are covered under multiple categories and corresponding category code numbers (CCNs) based on the type of coating and end-use application.
With expertise in safety science reaching back to 1894, UL is uniquely positioned to provide a complete view of how your products will function within a given system. This is particularly critical in the plastics and components industry. Interactions between substances, parts, systems and the environment can cause of a significant number of hazards and failures, which are rarely apparent when components are tested individually.
Our technical experts can also help you align your products to the appropriate UL Certification category and applicable Standards. This enables manufacturers of UL Certified products to easily source components that demonstrably meet their compliance needs and project specifications.
