Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by dire

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

15、ard 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-committee, C78-1 for Incandescent Lamps
16、. 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 in excess of the actual space re
17、quired. (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 typical form. The essential dimensions
18、 are controlled by the “Go” gauge for P28 based lamps described in ANSI C81.63. 0 (5) All dimensions are in millimeters unless otherwise specified. 4.4.2 The light source dimensions, width (W), height (H), and thickness (T) in Table 1, define a maximum size volume centered on the Light Center Length
19、 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 Restrictions 5.1 Operating Positions Lamp types in this standard may operate p
20、roperly in any position or they may be restricted as to position. Such restrictions are indicated in the Operating Position column of Table 1.
