BA9灯头通规|B15灯头通规|BA15灯头通规|B22灯头通规(GO GAUGE FOR BA9 B15, BA15 CAPS ON FINISHED LAMPS)7006-11-8
目的:
检验成品灯具上BA9、B15、BA15和B22灯头的尺寸Amax、Nmin、D1min和D1max,以及销钉的径向位置。
检验:
将灯头插入量规,直至其销钉通过狭槽Q。然后,将灯头转动一微小的角度,并将其按压,从而使其销钉与S面紧密接触。在此位置上形成接触的面不应低于X面,也不应凸出Z面。
注:如果规定要求检验GB/T1406.5-7004-11所示尺寸Dmax,可采用类似的量规检验未组装的B15灯头。
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.
