产品设计：广东安规检测有限公司

设计标准：7006-26D-1 E17灯头量规是广东安规根据标准IEC60061-3,GB/T1483.1的要求设计制作而成。

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。

The plunger of the gauge is shown in the test position. When the plunger is at rest, surface W shall be retracted deeper than surface V.

产品用途：

检验灯在E17灯座中有关接触性能的尺寸。

To check lamp dimensions for contact-making in E17 lampholders.

使用方法：

如果灯插入量规时，W面可与V面共面或凸出V面，则可认为灯的形状与灯座配合是合格的。

The shape of the lamp with regard to the fit in the lampholder is assumed to be correct, if the lamp can be pushed into the gauge until plane W reaches plane V or projects beyond it.
