2) A zinc coating, other than that provided on hot-dipped, mill-galvanized sheet steel, uniformly applied to an average thickness of not less than 0,00041 inch (0.013 mm) on each surface with a minimum thickness of 0.00034 Inch (0.009 mm). The thickness of the coating shall be established by the test indicated in 62.1 An annealed coating shall also comply with 13.9.
d) A cadmium coating not less than 0.0010 inch (0.025 mm) thick on both surfaces. The thickness of the coating shall be established by the test indicated in 62.1.
e) A cadmium coating not less than 0.00075 inch (0.019 mm) thick on both surfaces with one coat of outdoor paint on both surfaces, or not less than 0.00051 inch (0.013 mm) thick on both surfaces with two coats of outdoor paint on both surfaces. The thickness of the cadmium
coating shall be established by the test indicated in 62.1, and the paint shall be as described in 13.8(c).
f) Other finishes, including paints, special metallic finishes, and combinations of the two may be accepted when comparative test with galvanized sheet steel (without annealing, wiping, or
other surface treatment) conforming with 13.8(a) indicate that they provide equivalent resistance to corrosion. Among the factors that are taken into consideration when evaluating such coating systems are exposure to salt spray, moist carbon dioxide-sulfur dioxide mixtures, moist
hydrogen sulfide-air mixtures, ultraviolet light, and water. Organic coatings shall comply with the Standard for Organic Coatings for Steel Enclosures for Outdoor Use Electrical Equipment. UL

13.9 An annealed coating on sheet steel that is bent or similarly formed or extruded, or rolled at edges of holes after annealing shall be additionally painted in the affected areas if the process damages the zinc coating. When flaking or cracking of the zinc coating at the outside radius of the bent or formed section is visible at 25 power magnification, the zinc coating is considered to be damaged. Sheared or cut edges and punched holes are not required to be additionally treated.
14 Power Supply Connections — Cord-Connected and Convertible Spas and Equipment Assemblies
14.1 A non-detachable power supply cord shall be provided on each cord-connected and convertible spa and equipment assembly. When intended for indoor use, or both indoor and outdoor use, the electrical rating shall not exceed 20 amperes. When marked “For outdoor use only,” this restriction does not apply.
14.2 The cord mentioned in 14.1 shall be Type SW, SEW, SOW, STW, SEOW, SEOOW, STOW, STOOW or equivalent hard-service cord that is suitable for use outdoors and immersion in water with a grounding conductor and an attachment plug. The cord shall extend at least 10 feet (3.05 m) but no more than 15 feet (4.57 m) from the product to the face of the attachment plug.UL 1563-2017 pdf free download.
