21、TRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 This Standard covers sun lamps, heat lamps and combination sun and heat lamps rated at not more than 125 V. A sun lamp is intended for production of ultraviolet radiation for skin tanning. A heat lamp is intended for production of infrare
22、d radiation. A combination sun and heat lamp is intended for production of both ultraviolet and infrared radiation. In the text of this Standard, the term sun/heat lamp is intended to cover all types. 1.2 This Standard covers portable sun/heat lamps intended for use by nontechnically qualied persons
23、 in homes, sports facilities, health spas and similar establishments and intended for connection to a power-supply circuit by a exible cord for use in accordance with the National Electrical Code, ANSI/NFPA 70. 1.3 This Standard does not cover lamps intended primarily to provide illumination (althou
24、gh some visible radiation may be produced during the operation of a sun/heat lamp). 1.4 This Standard does not cover sun or heat lamps intended for professional use. Professional use lamps are those for use by technically qualied persons in hospitals, nursing homes, medical care centers, clinics, me
25、dical offices, laboratories, and similar establishments for therapeutic purposes. The therapeutic lamps are covered by the requirements for medical and dental equipment. 1.5 Ultraviolet lamps intended for high intensity, short duration 2 minute maximum rst exposure time for most sensitive skin opera
26、tion will be subject to an appropriate investigation for any additional requirements as are applicable to a lamp with this feature. 1.6 This Standard does not cover bulbs alone but complete appliances. 2 Components 2.1 Except as indicated in 2.2, a component of a product covered by this Standard sha
27、ll comply with the requirements for that component. See Appendix A for a list of standards covering components generally used in the products covered by this Standard. 2.2 A component is not required to comply with a specic requirement that: a) Involves a feature or characteristic not required in th
28、e application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.3 A component shall be used in accordance with its rating established for the intended conditions of use. 2.4 Specic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
29、restricted in performance capabilities. Such components 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.

Values in parentheses are explanatory or approximate information. 3.2 Unless indicated otherwise all voltage and current values mentioned
31、in this Standard are root-mean-square (rms). 4 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 latest edition of that code or standard. CONSTRUCTION 5 General 5.1 Portable sun lamps are subject to the
32、Radiation Control for Health and Safety Act of 1968, and the Federal Food, Drug and Cosmetic Act, as amended by the Safe Medical Act of 1990 and the Medical Device Amendments of 1992. 6 Frame and Enclosure 6.1 A sun/heat lamp shall be so formed and assembled that it has the strength and rigidity nec
33、essary to resist the abuses to which it is likely to be subjected without increasing its risk of re, electric shock, or injury to persons due to total or partial collapse with resulting reduction of spacings, loosening or displacement of parts, or other serious defects. 6.2 A sun/heat lamp shall hav
34、e an enclosure of metal or of noncombustible, nonabsorptive insulating material such as glass, marble, phenolic composition, or of a material determined to be acceptable for the application. 6.3 Among the factors taken into consideration when determining the acceptability of a nonmetallic enclosure
35、are: a) The mechanical strength, b) Resistance to impact, c) Moisture-absorptive properties, d) Combustibility and resistance to ignition from electrical sources, e) Dielectric strength, insulation resistance, and resistance to arc tracking, and f) Resistance to distortion and creeping at temperatur
36、es to which the material may be subjected under conditions of intended or abnormal usage. The material is not to display a loss of these properties beyond the minimum acceptable level as a result of aging. See the requirements in the Standard for Polymeric Materials Use in Electrical Equipment Evalu

SEPTEMBER 2, 2005 PORTABLE SUN/HEAT LAMPS - UL 482 7UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 6.4 The continuity of the grounding system shall not rely on the dimensional integrity of the nonmetallic material. 6.5 Elec
38、trical parts of a sun/heat lamp shall be so located or enclosed that protection against unintentional contact with uninsulated live parts, other than the contacts of a lampholder, is provided. 6.6 An opening in an enclosure that contains live or current-carrying parts shall prevent entrance of a 1 i
39、nch (25.4 mm) diameter rod and is acceptable if a probe as illustrated in Figure 6.1, inserted through the opening, cannot touch any uninsulated live part or coated-magnet wire that may cause an electric shock. The probe shall be applied in all possible articulated positions before, during, and afte

41、MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 6.7 During the examination of an appliance in connection with the requirements in 6.5, a part of the outer enclosure that may be removed, without the use of tools, by the user of the appliance (to permit the
42、attachment of accessories, to allow access to means for making operating adjustments, or for another reason) is to be disregarded that is, it will not be assumed that the part in question affords protection against the risk of electric shock. 6.8 The stability of a sun/heat lamp having a stand shall
43、 be such that it will not easily overturn under conditions of expected use. 6.9 A sun/heat lamp shall be so constructed that it will not tip over when resting on an inclined plane having an angle of 8 degrees with the horizontal. 6.10 Except for parts needed to perform a working function, an edge, p
44、rojection, or corner of an enclosure, opening, frame, guard, handle, or the like shall be smooth and well rounded and not so sharp as to constitute a risk of injury to persons in intended use or during user maintenance. 6.11 A guard that is not permanently secured in place is to be investigated to d
45、etermine its acceptability for the application. 7 Mechanical Assembly 7.1 A sun/heat lamp shall have all parts secured in an effective manner. 7.2 A switch that is housed in the enclosure of a lamp, and a lamp- or element-holder, shall be mounted securely and prevented from turning by means other th
46、an friction between surfaces. 7.3 A lockwasher properly applied is acceptable as a means to prevent turning of a stem-mounted switch. 8 Corrosion Protection 8.1 Iron and steel parts shall be protected against corrosion by galvanizing, plating, painting, enameling, or other equivalent means if the de
47、terioration of such parts would be likely to result in an increased risk of re, electric shock, or injury to persons. 8.2 If the oxidation of iron or steel due to the exposure of the metal to air and moisture is not likely to be appreciable thickness of metal and temperature also being factors the s
48、urfaces of sheet steel and cast iron parts in an enclosure may not be required to be protected against corrosion. The requirement of 8.1 does not apply to bearings, laminations, and the like.

49、ODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 9 Electrical Potentials 9.1 If a sun/heat lamp employs an autotransformer, no part of the lamp shall exceed a potential of 150 V to ground or to either conductor of the power-supply cord, when it is connected to a supply circuit of maximum rated voltage under any condition of operation, including open-circuit winding. If such a lamp employs a 2-winding transformer, the maximum difference of potential in the secondary shall be 300 V or
