Rosslyn, VA 22209 ANSI C78.1505-2001 Revision of ANSI C78.1505-1993 Am e rica n National Standard Approval of an American National Standard requires verification by 0 ANSI that the requirements for due process, consensus, and other criteria f
4、or approval have been met by the standards developer. An American National Standard implies a consensus of those substantially concerned with its scope and provisions. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by dire
5、ctly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. The use of American National Standards is
6、completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not deve
7、lop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the righ or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations
8、 should be addressed to the Committee Secretariat whose name appears on the title page of this standard. CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to r

14、ns for improvement of this standard should be submitted to the Secretariat C78, National Electrical Manufacturers Association, 1300 North 17th Street, Suite 1847, Rosslyn, VA 22209. This standard was processed and approved by Accredited Standards Committee on Electric Lamps, C78, and its Sub-Committ
15、ee, C78-1 for Incandescent Lamps. Committee approval of the standard does not necessarily imply that all committee members voted for that approval. At the time this standard was published, the C78 Committee had the following members: AI Rousseau, Chair, C78 all compromises with the actual space are
16、in excess of the actual space required. (2) All excursions of a lamp bulb are shown relative to a fixed-position base. (3) Bulb ?eccentricity? with respect to the base axis is a combination of allowances for angular tilt and lateral displacement. (4) The base shown in the drawing represents a typica
17、l form. The essential dimensions are controlled by the ?Go? gauge for G38 based lamps described in ANSI C81.63. (5) All dimensions are in millimeters unless otherwise specified. 4.4.2 The light source dimensions, diameter (D) and height (H) in Table 1 and width (W), height (H), and thickness (T) in
18、Table 2, define a maximum size volume centered on the Light Center Length and base axis within which all luminous parts of the filament are located. This volume accounts for all positions of the filament. Actual filament size may be significantly smaller than the defined light source volume. 5 Restr

Such restrictions are indicated in the Operating Position column of Tables 1 and 2. Copyright O 2001 by American National Standards Lighting Group in Affiliation

21、ed 35OOC for lamps with rated life of 500 hours and 4OOOC for lamps with a rated life of 500 hours or less. 5.3 Bulb Wall Temperature A lamps bulb wall temperature shall be maintained about 25OOC for proper operation of the halogen cycle. An upper limit of approximately 900C is recommended for maint
22、aining the integrity of fused silica bulbs. 5.4 Shielding A protective shield shall be provided relevant to the following cautionary notice. To assure maximum safety during handling and use of the subject lamps, observe the following notices: (1) Tungsten-halogen-lamps operate at high temperature an
23、d at internal gas pressures above atmospheric pressure. Consequently, a lamp could shatter. Certain lamps may also emit some amount of ultraviolet radiation. Therefore a suitable protective shield, screening technique, or both shall be used with the luminaire to protect people and surroundings from
