E26接触规IEC 7006-29-3/E26灯头量规
1) The value is for lamps fitted with E26/24 caps. For lamps fitted with E26/25 caps, dimension K is 29.3mm. 这里的值适用于E26/24灯头，如果是E26/25灯头，K应该为29.3mm.
2) The value is for lamps fitted with E26/24 caps. For lamps fitted with E26/25 caps, dimension M is 25.9mm. 这里的值适用于E26/24灯头，如果是E26/25灯头，M应该为29.3mm.
3) The gauge is shown in the test position. In the rest position the plunger shall be above plane V. 图中所示量规柱塞处于检验状态，当柱塞处于静止状态时，W面应比V面缩进更深些。
4) Only for E26/24,仅对E26/24

Purpose目的：
To check lamp dimensions for contact making in IEC holders.
检验灯在灯座中有关接触性能的尺寸。
Testing 测试方法：
The shape of the lamp with regard to the fit in the lampholder is assured to be correct. If the lamp can be pushed into the gauge till plane W reaches plane V or project beyond it.
如果灯插入量规时，W面可与应V面共面或凸出V面，则可认为灯的形状与灯座的配合是合格的。
For E26/24 capped lamps, when surfaces V and W are coincident, the top of the cap including any solder or conductive material, shall not extend above surface X.
对于E26/24灯头的灯，当V面与W面共面时，灯头顶部的焊锡或任何导电部分不能升出X面。
