E12燈頭通規(guī):7006-27H-1
E12Go gauge for caps on finished lamps: 7006-27H-1
目的:
PURPOSE:
檢驗成品燈上E12燈頭螺紋尺寸和尺寸T1min。
To check the maximum dimension of the screw thread and dimension T1 minimum of E12 caps on finished lamps.
檢驗:
TESTING:
當(dāng)成品燈上的燈頭完全旋入量規(guī)內(nèi)時,燈頭中心觸點應(yīng)與量規(guī)X面接觸,當(dāng)從量規(guī)中取出時,至少應(yīng)旋轉(zhuǎn)兩圈才能脫離螺紋。
此量規(guī)僅與本部分中參數(shù)表7006-27J規(guī)定的量規(guī)配合使用。
When the cap on finished lamps has been screwed into the gauge as far as it will go, the centre contact shall touch surface X. When the lamp is being removed from the gauge, at least two full turns shall be required to disengage the threads. This gauge should be used only in conjunction with the gauge specified on sheet 7006-27J.

E12 Not Go gauge for caps on finished lamps 7006-28C-1
目的:
PURPOSE:
檢驗成品燈上E12燈頭螺紋外徑(尺寸d)。
To check the minimum outside (major) diameter of the screw thread, dimensiion d, of E12 caps on finished lamps.
檢驗:
TESTING:
當(dāng)量規(guī)套在成品燈(燈頭朝上)的燈頭螺紋上時,燈頭中心觸點不應(yīng)凸出量規(guī)的X面。
When the gauge is placed over the thread of the cap on a finished lamp, held cap uppermost, the centre contact shall not project beyond surface X. 檢驗僅利用量規(guī)自身重量進行。
Only the mass of the gauge itself shall be used in the test.
