UL 482 Standard For Portable Sun/Heat Lamps

5.7 During the examination of an appliance in connection with the requirements in paragraph 5.5, a part of the outer enclosure that may be removed, without the use of tools, by the user of the appliance (to permit the 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 electric shock.

5.8 The stability of a sun/heat lamp having a stand shall be such that it will not easily overturn under conditions of expected use.

5.9 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.

5.10 Except for parts needed to perform a working function, an edge, projection or corner of an enclosure, opening, frame, guard, handle or the like shall be smooth and well rounded and not sufficiently sharp to constitute a risk of personal injury in intended use or during user maintenance.

5.11 A guard that is not permanently secured in place is to be investigated to determine its acceptability for the application.

6.1 A sun/heat lamp shall have all parts secured in a substantial and reliable manner.

6.2 A switch that is housed in the enclosure of a lamp, and a l amp- or element-holder, shall be mounted securely and prevented from turning by means other than friction between surfaces.

6.3 A lock washer properly applied is acceptable as a means to prevent turning of a stem-mounted switch.

7.1 Iron and steel parts shall be protected against corrosion by galvanizing, plating, painting, enameling, or other equivalent means if the deterioration of such parts would be likely to result in an increased risk of fire, electric shock or personal injury.

7.2 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 surfaces of sheet steel and cast iron parts in an enclosure may not be required to be protected against corrosion. The requirement of paragraph 7.1 does not apply to bearings, laminations and the like.
