【正文】 ic or electrostatic fields need not ply with this requirement. Where loosening or breaking of electrical connections involves a risk of fire or electric shock, the connections shall be soldered, welded, or otherwise securely connected. A soldered joint shall be mechanically secure before soldering.Exception: A surface mount ponent with a maximum dimension of 13 mm ( inch) need not ply with this requirement. An insulated conductor shall have insulation rated for the voltage, temperature, and conditions of intended use. A device lampholder not plying with shall ply with Section, Lamp Starting and Operating Measurements. A device lampholder or device base shall ply with the appropriate requirements of the Standard for EdisonBase Lampholders, , and the Standard for Lampholders, Starters, and Starter Holders for Fluorescent Lamps,. Provided with strainrelief means that plies with the Strain Relief Test For Circular Fluorescent Lamps, Section. Free of burrs, sharp edges, and the like, that may abrade the insulation, andc) Close fitting to the emerging leads,b) A hole in an enclosure through which wires emerge to connect with a lamp connector shall be:a) An enclosure shall not have openings wider than 2 mm ( inch), unless they do not permit a 2 mm ( inch) diameter rod of any length to contact live parts.Exception: The uninsulated live parts of a lampholder into which a lamp connects are not required to ply. a Uncoated sheet steel with a minimum of mm ( inch) is acceptable if the ballast part of the device is filled with potting pound. ()Nonferrous sheet metal ()Minimum thickness, mm (inch) An enclosure shall be of metal or of a polymeric material that plies with Section, Polymeric Materials. 5 Enclosure 4 Assembly and Packaging References If a unit of measurement is followed by a value in other units in parentheses, the second value may be only approximate. The first stated value in International System (SI) units is the requirement. Specific ponents are recognized as being inplete in construction features or restricted in performance capabilities. Such ponents are intended for use only under limited conditions, such as certain temperatures not exceeding specified limits, and shall be used only under those specific conditions for which they have been recognized. Is superseded by a requirement in this standard. Involves a feature or characteristic not needed in the application of the ponent in the product covered by this standard, orb) A ponent need not ply with a specific requirement that:a) Components Figure Sample device SUPPLY LAMPHOLDER The Edisonbase lampholder of an incandescent lighting fixture or portable electric lamp that can acmodate and supply power to a selfballasted lamp or lamp adapter. For powerfactor correction across the input leads of the ballast or across an extension of the primary winding. In series with a lamp or lamps and provides the ballast impedance for the lamp current, orb) POWER CAPACITOR A capacitor used with a magnetic ballast that is connected:a) b) DRY LOCATION A location not normally subject to dampness, but may include a location subject to temporary dampness as in the case of a building under construction, provided ventilation is adequate to prevent an accumulation of moisture. LOCATION LAMP CONNECTOR A set of contacts attached to flexible conductors which provide a removable means for electrical connection to a lamp but does not provide mechanical support. ELECTRONIC BALLAST A ballast, generally involving high frequency switching that is controlled by active ponents (transistors, thyristors, and the like), and with the lamp ballasting impedance provided by a series capacitive or inductive reactance appropriate for the high switching frequency. DEVICE LAMPHOLDER The lampholder provided for the replaceable fluorescent light source. The term device is used to denote fluorescent selfballasted lamps and fluorescent lamp adapters covered by this standard. The name of the device is used if a requirement applies to only one of them. 2 Glossary These devices are not intended for use with emergency exit fixtures or emergency exit lights. These devices incorporate resistance, reactance, or electronic (solid state) type ballasts. 1 Scope s OnLine Collaborative Standards Development System (CSDS) at ISBN 0762912472COPYRIGHT 169。s puter system.If a singleuser version electronic Standard was purchased, one copy of this Standard may be stored on the hard disk of a single personal puter, or on a single LAN fileserver or the permanent storage device of a multipleuser puter in such a manner that this Standard may only be accessed by one user at a time and for which there is no possibility of multiple concurrent access.If a multipleuser version electronic Standard was purchased, one copy of the Standard may be stored on a single LAN fileserver, or on the permanent storage device of a multipleuser puter, or on an Intranet server.
