15、 (altitude) rating”, and altitude, maximum peak voltage in the basic document. 3. Cycle (or vary) the tube current between 1.5 and 3.5 mA. 4. Conditions for this test shall be those of ionization voltage (1), except testing shall be done in total darkness, and the tube shall not have conducted or ha
16、ve been exposed to light for at least 24 hours prior to testing. 5. Repeatability shall be defined as the maximum shift in tube voltage drop between successive firings of the tubs. The tube shall be tested in the following manner: (a) The voltage drop shall be read at, 2.5 mAdc drain. (b) The tube s
17、hall be turned off for 1 minute. (c) The tube shall be restarted and operated at the same current. (d) The voltage drop shall be read after 1 minute of operation. (e) The “on-off” cycle shall be repeated a minimum of five times. The maximum difference in tube voltage drop shall be taken as the measu
18、re of repeatability. 6. This test shall be conducted on the initial lot and thereafter on a lot approximately every 6-months. When one lot has passed, the 6-month rule shall apply. 7. Envelope temperature (TE) requirements, when measured in accordance with the temperature by conduction-band measurem
19、ent (method 1226), will be satisfied if a tube having bogey tube drop (Etd = 3 percent) under normal test conditions, is determined to operate at minimum specified temperature at any position in the life-test rack. 8.
