When the gauge is placed over the thread of the cap on a finished lamp, held cap uppermost, the center contact shall not project beyond surface “X”. Only the weight of the gauge itself shall be used in the test.

當(dāng)量規(guī)套在成品燈的燈頭螺紋上時(shí)，燈頭中心觸點(diǎn)不應(yīng)凸出量規(guī)的X面，見(jiàn)嚴(yán)禁利用量規(guī)的自身重量進(jìn)行。
