19、electric lighting xtures used for area lighting. 1.2 These requirements also cover receptacle devices equipped electrically and mechanically to receive the light-sensitive control units described in 1.1. 1.3 Shorting and open-circuit devices, used as substitutes, where necessary, for the light-sensi
20、tive control units described in 1.1, are also covered by the requirements in this standard, where applicable. 1.4 These requirements do not cover photoelectric switches, intended for residential, industrial or commercial use, of the non-plug-in, nonlocking type. 2 Components 2.1 Except as indicated
21、in 2.2, a component of a product covered by this standard shall comply with the requirements for that component. 2.2 A component is not required to comply with a specic requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered b
22、y this standard, or b) Is superseded by a requirement in this standard. 2.3 A component shall be used in accordance with its rating established for the intended conditions of use. 2.4 Specic components are incomplete in construction features or restricted in performance capabilities. Such components
23、 are intended for use only under limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic conditions.

24、its of Measurement 3.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 4 Undated References 4.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the
25、 latest edition of that code or standard. 5 Glossary 5.1 ACCESSIBLE PART A part so located that it can be contacted by a person, either directly or by means of a probe or tool. 5.2 CONTROL RECEPTACLE An outlet device equipped electrically and mechanically to receive a control unit having a standard

27、parts that have a potential difference with respect to ground or any other conductive part. 5.5 OPEN-CIRCUIT PLUG A device similar in construction to a shorting plug, but intended to maintain a lighting xture in the off mode of operation until removed. 5.6 SHORTING PLUG A plug-in, locking type devic
28、e, having the same standard 3-blade plug conguration as a control unit and which provides an electrical connection through the control receptacle of an outdoor electric lighting xture, without performing a control function. A shorting plug is used as a substitute, where necessary, for a control unit
29、 and maintains a lighting xture in the on mode of operation until removed. CONSTRUCTION ALL EQUIPMENT 6 General 6.1 The requirements detailed in Sections71 0a r eapplicable to all equipment covered by this standard. Requirements applicable to specic equipment only are detailed separately. MARCH 18,

The base shall be so constructed tha
31、t, considering the material used, it will withstand the most severe conditions likely to be encountered in service. 7.2 Insulating material, including barriers between parts of opposite polarity and material that may be subject to the inuence of the arc formed by the opening of contacts, shall be ac
32、ceptable for the particular application. 7.3 Vulcanized ber may be used for insulating bushings, washers, separators, and barriers, but not as the sole support for uninsulated live parts. 8 Corrosion Protection 8.1 Iron and steel parts, except for thermal elements, magnet-pole faces, hardened and po
33、lished parts such as latching surfaces, and the like where such protection is impractical, shall be protected against corrosion by enameling, galvanizing, plating, or other equivalent means. 8.2 Phosphate treatment with an oil or wax coating is acceptable as corrosion protection for magnets and arma
34、tures; oil treatment is acceptable as corrosion protection for steel springs; and stainless steel is acceptable without additional protection, if properly polished or treated. 8.3 All surfaces of a metal enclosure, and all attached metal parts of an enclosure, shall be protected against corrosion by
35、 one of the coatings described in 8.4 8.6, unless the metal is inherently resistant to corrosion. Metals shall not be used in combinations as to cause galvanic action that will adversely affect any part of the device. 8.4 A sheet steel enclosure shall be protected against corrosion by one of the coa
36、tings as specied in (a) (f). a) Hot-dipped mill galvanized sheet steel conforming with the coating Designation G90 in Table I of ASTM Designation A653/A653M, with not less than 40 percent of the zinc on any side, based on the minimum single spot test requirement in this ASTM Designation. The weight
37、of the zinc coating may be determined by an acceptable method; however, in case of question the weight of coating shall be established in accordance with the test method of ASTM Designation A90. b) A zinc coating, other than that provided on hot-dipped mill galvanized sheet steel, uniformly applied
38、to an average thickness of not less than 0.00061 inch (0.015 mm) on each surface with a minimum thickness of 0.00054 inch (0.014 mm). The thickness of the coating shall be established by the chromic acid dropping test as described in 8.5. An annealed coating shall comply with 8.6. c) A zinc coating
39、conforming with item 1 or 2 and with one coat of an organic nish of the epoxy or alkyd-resin type or other outdoor paint on both surfaces after forming. The acceptability of the paint may be determined by consideration of its composition or by corrosion tests if these are considered necessary. 1) Ho
40、t-dipped mill galvanized sheet steel conforming with the coating Designation G60 or A60 in Table I of ASTM Designation A653/A653M, with not less than 40 percent of the zinc on any side, based on the minimum single spot test requirement in this ASTM Designation. The weight of zinc coating may be dete
41、rmined by any acceptable method; MARCH 18, 2016 UL 773 7UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL however, in case of question the weight of coating shall be established in accordance with the test method of ASTM Designation A90. An A6
42、0 (alloyed) coating shall also comply with 8.6. 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 (0.010 mm) on each surface with a minimum thickness of 0.00034 inch (0.009 mm). The thickness
43、 of the coating shall be established by the chromic acid dropping test as described in 8.5. An annealed coating shall also comply with 8.6. d) A cadmium coating not less than 0.0010 inch (0.025 mm) thick on both surfaces. The thickness of coating shall be established by the chromic acid dropping tes
44、t as described in 8.5. 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 coa
45、ting shall be established by the chromic acid dropping test as described in 8.5 and the paint shall be as specied in (c). f) Other nishes, including paints, special metal nishes, or combinations of the two may be accepted when comparative tests with galvanized sheet steel (without annealing, wiping
46、or other surface treatment) as specied in (a), indicate they provide equivalent protection. Among the factors which are taken into consideration when evaluating the acceptability of such coating systems are exposure to salt spray, moist carbon dioxide-sulphur dioxide-air mixtures, moist hydrogen sul
47、phide-air mixtures, ultraviolet light, and water. 8.5 The method of determining the thickness of coating by the chromic acid dropping test as specied in (a) (h). a) The solution to be used for the chromic acid dropping test is to be made from distilled water and is to contain 200 g/L of chemically p
48、ure chromic acid (CrO 3 ) and 50 g/L of chemically pure concentrated sulphuric acid (H 2 SO 4 ). (The latter is equivalent to 27 mm/L of chemically pure concentrated sulphuric acid, specic gravity 1.84, containing 96 percent of H 2 SO 4 .) b) The test solution is to be contained in a glass vessel, s
49、uch as a separatory funnel, with the outlet equipped with a stopcock and a capillary tube of approximately 0.025 inch (0.64 mm) inside bore and 5.5 inches (140 mm) long. The lower end of the capillary tube shall be tapered to form a tip, the drops from which are to be about 0.05 mm each. To preserve an effectively constant level, a small glass tube is to be inserted in the top of the funnel through a rubber stopper and its position adjusted so that, when the stopcock is open, the rate of dro
