E12燈頭通規：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:
當成品燈上的燈頭*旋入量規內時，燈頭中心觸點應與量規X面接觸，當從量規中取出時，至少應旋轉兩圈才能脫離螺紋。
此量規僅與本部分中參數表7006-27J規定的量規配合使用。
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.

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:
當量規套在成品燈（燈頭朝上）的燈頭螺紋上時，燈頭中心觸點不應凸出量規的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. 檢驗僅利用量規自身重量進行。
Only the mass of the gauge itself shall be used in the test.
