Purpose目的：
To check the dimensions S1 minimum and S1 maximum of E27 caps on finished lamps.
检验成品灯上E27灯头尺寸S1的最大值和最小值。
Testing 测试方法：
When the cap on a finished lamp has been pushed into the gauge as far as it will go, the plunger surface “W” shall be co-planar with or project beyond surface “X” but it shall not project beyond surface “Y”.
当成品灯的灯头完全插入量规时，塞柱的W面应与X面共面或凸出X面，但不得凸出Y面。
