CONSTRUCTION 5 General 5.1 Portable sun lamps are subject to the Radiation Control for Health and Safety Act of 1 968, and the Federal Food, Drug and Cosmetic Act, as amended by the Safe Medical Act of 1 990 and the Medical Device Amendments of 1 992. 6 Frame and Enclosure 6.1 A sun/heat lamp shall be so formed and assembled that it has the strength and rigidity necessary to resist the abuses to which it is likely to be subjected without increasing its risk of fire, 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 have 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.
6.7 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 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 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. 6.1 0 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 so sharp as to constitute a risk of injury to persons in intended use or during user maintenance. 6.1 1 A guard that is not permanently secured in place is to be investigated to determine its acceptability for the application.
