19、 ANSI C78.370-1997 7 ANSI C78.390-1998 7 Resolution Procedure If a manufacturer wishes to lodge an objection to the issuance of a new lamp code designation number, or to a proposed alternative or change to an existing number, The Program Administrator must be notified in writing within 42 days after

20、 distribution to the appropriate industry representatives. The Administrator shall then notify the participants that an objection has been filed, and no designation will be assigned to the request, nor will any change in the recorded characteristics be made, pending resolution by the Administrator i

21、n consultation with both parties. Should the Administrator be unable to resolve to both parties satisfaction, the item of dispute shall be deferred to the appropriate subcommittee for resolution at their next regularly convened meeting. If by the 61 day, no comments or objections are received, the l

22、amp code designation is considered approved, and any objection received after that time must go through an appeals process, during which the objecting manufacturer must explain in writing why the disputed lamp code was not questioned during the 42 day comment period, and what detrimental effect the

23、new code will have on that company. On/after the 60th day, the company making application for the new code may start using the new Lamp Code Designation . The 42 day comment period relates to the letter ballot period, but because of the nature of this work, 1 an additional 18 days is often granted.

33、22209 First Edition December 1997 ANSI C78.370-1997 Revision of ANSI C78.370-1982 (R1995) FOREWORD (This foreword is not part of ANSI C78.370-1987.) As stated in the scope of this standard, the intended application of the three letter code is only for photographic, stage and studio lamps. Recent dis

34、cussion by Subcommittee C78-5 has refined the interpretation of photo lamps as those whose primary applications are associated with the taking, processing, duplicating, viewing and projection of images. Such an interpretation does not encompass lamps for display, floodlighting or spotlighting applic

35、ations. In actual practice some designation codes have been assigned to lamps for display service. However, designation codes on such lamps do not appear to offer any advantage in controlling correct lamp replacement. Regular lamp ordering abbreviations such as those used on regular PAR lamps are mo

36、re meaningful. Therefore, Accredited Standards Committee C78 on Electric Lamps plans to cease the assignment of designation codes to display lamps after a suitable adjustment period. Three years from the approval date of this supplement to ANSI C78.370, the administrator will discontinue assignment

37、of designation codes to display lamps. The scope and related sections of the standard C78.370 will then be appropriately revised. During this period, lamp manufacturers should consider dual marking of lamp identification codes and revising the lamp catalogs as necessary. This standard contains annex

38、es. Annexes A - D are normative and considered part of this standard; Annex E is informative and is not considered pari of this standard.

48、1 Scope This standard describes a system for the designation of photographic, stage and studio lamps. A form is provided for the use of lamp manufacturers to request a designation assignment, altemative, or change. 1.2 Purpose The purpose of the designation system defined by this standard is to prov

49、ide a nationally applicable and convenient lamp identification that may be used for both manufacturing and ordering purposes. The designation will ensure, for the user, the interchangeability of lamps that bear the same designation. The lamp characteristics data given by a manufacturer on a Lamp Designation Request Form (Request Form) forms the basis for the assignment of a designation. They have not been approved by the American National Standards Institute (ANSI) and do not constitute an American National Standard. 2 Normative references The following standards contain provisio
