2、 li - EIA TEP333-A bb W 3234b00 0008373 5 SCOPE This publication provides the criteria for television picture bulbs and implosion panels. The individual items specified herein are, for the most part, those which are of some comercial interest within the United States at this time. Other television p
3、icture bulbs are being produced, new bulbs undoubtedly will be pro- duced after this is issued, and the amount of commercial interest in different bulbs has been known to fluctuate considerably. Therefore, no deductions should be drawn from the inclusion or exclusion of a particular bulb from this d
4、ocument. This publication was initially intended as a revision of JEDEC Publication 10, Cathode-Ray Tube Bulb Criteria, dated November 19, 1956. However, the Committee on Cathode-Ray Tubes, JT-6, concluded that it would be ad- vantageous to divide the CRT bulb criteria into two unique publications -
5、 this one and a subsequent publica- tion restricted to the criteria of bulbs for industrial and military CRT, This publication is therefore a re- placement of that part of Publication 10 dealing with television picture bulbs. -2- i EIA TEPL3L-A bb = 3234600 0008174 7 GENERAL INDEX PAGE - SUBJECT Sco
