3、h Street, Suite 1847, Rosslyn, VA 22209 First Edition May 1998 American National Standard Approval of an American National Standard requires verification by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. An American Na
4、tional 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 directly and materially affected interests. Substantial agreement means
5、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 existence of an American National Standard does not in any respect preclude anyone, whether he has approve
6、d the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. It is intended as a guide to aid the manufacturer, the consumer, and the general public. The American National Standards Institute does not develop standards
7、 and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be a
8、ddressed to the Committee Secretariat referred to on the title page. CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time.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 reaffirm, revise, or withdraw this st

19、ensional limits and other physical characteristics required to ensure the interchangeability and to assist in the proper application of a specific category of lamps. This category is tungsten-halogen lamps with GZ9.5 two-pin . prefocus bases and 36.5mm (1.5 inches) nominal light center length. Lamps
20、 of various design voltages are included. Lamps with the specifications listed in this standard are intended for projector, stage and studio applications. The grouping of lamps in this standard is based on general physical characteristics. It does not imply that the lamps listed are interchangeable
21、with each other in particular application. 2 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this American National Standard.

25、 for assigning lamp designations as defined in ANSI C78.370 is commonly employed for the lamps described in this standard. 4 Physical Characteristics 4.1 Bulb Designations Bulb designations are defined in ANSI C79.1. In this standard bulbs are described by metric designations, with customary designa
26、tions in parentheses. 4.2 Base Specification Finished lamps employing the GZ9.5 two-pin prefocus base shall comply with the detailed base requirements given in ANSI C81.61. Base gauging procedures are found in ANSI C81.63. 4.3 Lamp Characteristics Physical (nominal), electrical, and other characteri
27、stics of standard- lamps are shown in Table l. 4.4 Dimensions 4.4.1 The lamp space drawing, Figure 1 shows the maximum limits of the space that may be occupied by any part of a bulb. The dimensions shown will accommodate the longest (MOL) and shortest lamps with maximum bulb diameters (D) and maximu
28、m bulb excursion (E) with respect to the base axis. A typical bulb is shown. 4.4.2 The light source dimensions, (W), (H), and (T) of Table 1 define a 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 pos
29、itions of the filament. Actual filament size may be significantlysmaller than the defined light source volume. 2 Copyright O 1997 by National Electrical Manufacturers Association 1300 North 17th Street, Suite 1847.

30、arked with the relevant code in. accordance with the photo lamp designation system, ANSI C78.370. 4.5.2 Durability The area of the marking on an unused lamp shall withstand, maintaining legibility, the application of a rubbing test. This test involves rubbing by hand with a smooth cloth, dampened wi
31、th water, for a period of 15 seconds. 5 Restrictions 5.1 Operating Position Lamp types in this standard may operate properly in any position or they may be restricted as to position. Such restrictions are indicated in the Operation Position column of Table l. 5.2 Seal Temperature in the lamps covere
32、d by this standard, the metal-to-envelop seal is intended for operation at temperatures not to exceed 400C. 5.3 Bulb Wall Temperature A lamps bulb wall temperature shall be maintained above 250C for proper operation of the halogen cycle. The upper limit is approximately 900C. To avoid high temperatu
33、res, a cooling system should be used. 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 and at i
34、nternal gas pressures above atmospheric pressure. Consequently, a lamp could shatter. Certain lamps may also emit some amount of ultraviolet radiation. Copyright O 1997 by National Electrical Manufacturers Association 1300 North 17th Street, Suite 1847, Rosslyn, VA 22209 3 Fit Edition May 1998 There
35、fore, a suitable protective shield, screening technique, or both shall be used with the luminaire to protect people and surroundings from both hazards. (2) Always read and observe the information contained in the lamp manufacturers caution notice. 6 Test Procedures 6.1 Life Lamps shall be tested in
36、open racks, at the base-down or horizontal operation position * with cooling to maintain temperature limits. Additional procedures are defined in ANSI C78.1450. 6.2 Seal (Pinch) Temperature The measurement procedure is defined in IEC 60682. 6.3 Operating Temperature Standard methods of measuring oth
37、er lamp operating temperatures (bulb and base) are under consideration. 7 Information for Luminaire Design Proper luminaire design must take into account the several aspects of lamp restrictions mentioned in Section 5, operating position, seal temperature, bulb wall temperature, and shielding. 4 Cop
