目的：
檢驗成品燈具上BA9、B15、BA15和B22燈頭的尺寸Amax、Nmin、D1min和D1max，以及銷釘?shù)膹较蛭恢谩?/span>
檢驗：
將燈頭插入量規(guī)，直至其銷釘通過狹槽Q。然后，將燈頭轉(zhuǎn)動一微小的角度，并將其按壓，從而使其銷釘與S面緊密接觸。在此位置上形成接觸的面不應低于X面，也不應凸出Z面。
注：如果規(guī)定要求檢驗GB/T1406.5-7004-11所示尺寸Dmax,可采用類似的量規(guī)檢驗未組裝的B15燈頭。
Purpose:
To check dimension A max. , N min. , Di min. , Di max. , and the diametrical position of the pins of caps BA9, BA15 and B22 on finished lamps.
Testing:
The cap shall enter the gauge until the pins have passed through the slots Q. The cap is then turned through a small angle and is pressed so that the pins are in close contact with surface S. In this position, the contact-making surface shall not be below surface X nor shall it project beyond surface Z.
Note: A similar gauge may be used for checking unmounted caps B15 provided that provision is made for checking dimension D max. as shown on sheet 7004-11.

目的：
分別檢驗成品燈上BA9、B15、B22和BY22d燈頭的尺寸Amin.
檢驗：
如果量規(guī)僅靠其自身重量不能套進成品燈頭上，則該燈頭應視為合格。檢驗B15燈頭的量規(guī)也可用于檢驗未組裝的燈頭。
檢驗B15燈頭的量規(guī)也可用于檢驗未組裝的燈頭。
Purpose:
To check dimension A min. of caps BA9, B15, B22 and BY22d on finished lamps respectively.
Testing:
Caps on finished lamps shall be assumed to be correct if the gauge does not pass over the cap by its own weight.
The gauge for B15 may also be used for checking unmounted caps.
