(ANSI) that the requirements for due process, consensus, and other criteria for approval have b

13、een 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 directly, and material

14、ly 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 existence of an American National Standard does not in

15、any respect preclude anyone, whether s/he has approved 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 Na

16、tional Standards Institute, Inc., does not develop standards 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 S

17、tandards Institute, Inc. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on this title page. CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute, Inc., r

24、ciation ANSI C78.1501-2016 Page 1 2016 National Electrical Manufacturers Association 1 Scope This standard defines the dimensional limits and other physical characteristics required to ensure interchangeability and assist in the proper application of a specific category of lamps. This category is tu

25、ngsten-halogen lamps with G22 bases and 63.5 mm (2 in.) nominal light center length. Lamps of various design voltages are included. Lamps with the specifications listed in this standard are intended for stage and studio applications. The grouping of lamps in this standard is based on general physica

26、l characteristics. It does not imply that the lamps listed are interchangeable with each other in a particular application. Other tungsten-halogen lamps for stage and studio applications are described in standards listed in Annex B. Certain lamps in this standard are compatible with IEC 60357. 2 Nor

27、mative References The following standards contain provisions that, through reference in this text, constitute provisions of this American National Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this A

This test involves rubbing by hand with a smooth cloth, dampened with water, for a period of 15 seconds. 4 Physical Characteristics 4.1 Bulb Designations Bulb designations are defined in ANSI C79.1. In this standard, bulbs are descri

33、bed by metric designations, with customary designations in parentheses. 4.2 Base Specification Finished lamps employing the G22 base shall comply with the detailed base requirements given in ANSI C81.61.

34、ical Manufacturers Association 4.3 Lamp Characteristics Physical, electrical, and other characteristics of standard lamps are shown in Table 1, with tolerances as appropriate. 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 par

35、t of a bulb. The space shown will accommodate the longest and shortest lamps with maximum bulb diameters, and maximum bulb excursion with respect to the base axis. A typical bulb is shown as a dashed line within the maximum space. The following general conditions apply to the construction of these d

36、rawings: a. Straight lines are used as much as possible to simplify the outline; all compromises with the actual space are in excess of the actual space required. b. All excursions of a lamp bulb are shown relative to a fixed-position base. c. Bulb “eccentricity” with respect to the base axis is a c

37、ombination of allowances for angular tilt and lateral displacement. d. The base shown in the drawing represents a typical form. The essential dimensions are controlled by the “Go” gauge for G22-based lamps described in ANSI C81.63. e. All dimensions are in millimeters (mm) unless otherwise specified

38、. 4.4.2 The light source dimensionswidth (W), height (H), and thickness (T)in Table 1, 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 s

39、ize may be significantly smaller than the defined light source volume. 5 Restrictions 5.1 Operating Positions 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 Operating Position column of Table 1. ANSI

40、C78.1501-2016 Page 4 2016 National Electrical Manufacturers Association 5.2 Seal Temperature In the lamps covered by this standard, the metal-to-envelope seal is intended for operation at temperatures not to exceed 400C. 5.3 Bulb Wall Temperature A lamps bulb wall temperature shall be maintained at

41、about 250C for proper operation of the halogen cycle. An upper limit of approximately 900C is recommended for maintaining 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

42、 use of the subject lamps, observe the following notices: a. Tungsten-halogen lamps operate at high temperature and 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 protec

43、tive shield, screening technique, or both shall be used with the luminaire to protect people and surroundings from both hazards. b. Always read and observe the information contained in the lamp manufacturers caution notice. 6 Test Procedures 6.1 Life Lamps shall be tested in open racks or fixtures i

44、n their specified operating position with cooling to maintain the bulb and seal temperature limits. Suggested test cycles and additional testing procedures are defined in ANSI C78.1450. It should be noted that life-test results from an open rack test procedure may not be representative of lamp life

45、in luminaires or projection equipment. Consult the lamp manufacturer for specific test criteria. 6.2 Seal (Pinch) Temperature The measurement procedure is defined in ANSI/IEC C78.682. ANSI C78.1501-2016 Page 5 2016 National Electrical Manufacturers Association 6.3 Operating Temperature Standard meth

46、ods of measuring other 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,

47、and shielding.
