20、ogram Administrator must be notified in writing within 42 days after 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 recorde
21、d characteristics be made, pending resolution by the Administrator in 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 meet
22、ing. If by the 61 day, no comments or objections are received, the lamp 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 questione
23、d during the 42 day comment period, and what detrimental effect the 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
24、 the nature of this work, 1 an additional 18 days is often granted.

35、(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 discussion by Subcommittee C78-5 has refined the interpretation of photo lamps as tho
36、se 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 applications. In actual practice some designation codes have been assigned to lamps for
37、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 more meaningful. Therefore, Accredited Standards Committee C78 on Electric Lamps pla
38、ns 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 of designation codes to display lamps. The scope and related sections of the stand
39、ard 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 annexes. Annexes A - D are normative and considered part of this standard; Annex E is i
40、nformative and is not considered pari of this standard.
