Purpose目的：

To check protection against accidental contact during insertion of caps E27 on finished lamps.

检验成品灯上E27灯头在插入时防止意外接触性能。

Testing 测试方法：

 The shape of the lamp with regard to protection against accidental contact is assumed to be correct if, when the lamp is pushed as far as possible into the gauge, surface W does not protrude beyond surface V.

如果灯头*插入量规时，W面没有凸出V面，则可认为灯的防意外接触性能是合格的。

产品图纸：

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.

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。
