handling.

我的灯头如下图(我的灯就像是那些烧香的那种烛灯):

是里面一个螺旋灯泡座（内黑线框），再在外面用灯柱组合而成一个E10的灯头，E10泡子从上部旋进已组合的灯座。

我想请问，这个里面的灯泡座（黑线框）算不算是8.2.6提到的COVER？？？
若装进灯泡后，这个灯泡(红色椭圆状)又是不是8.2.6中所提到的other parts？？？

若答案是肯定的，那做拉力又该如何实施？我是直接拉灯泡来测试里面的灯泡座与外壳之间的稳定性可以吗？谢谢！

无人分享一下经验???自己先顶.

黑色线框不算是Cover，外面红色线框应该可以看成是Cover。我理解的Cover是包裹基本绝缘。按照你图片结构分析黑色线框部分它是一个基本绝缘整体。

至于测试你应该分清楚：你说的拉力测试？？？我想你在仔细的理解一下这个章节的意思。

楼主，根据我的理解，这项考核类似插头插座IEC 60884-1标准的条款。
这个COVER你所画出的都不属于，它应该类似于产品外壳，比方说墙壁插座，它有一个提供防触电的外盖板，这个盖板就是COVER，因为没有专门的固定装置（如螺钉），但要求这个盖板不能随便取下，但在力度较大时又必须取下，所以规定了两个力，施加小力时取不下，大力时必须取下。这里就是20和80N，灯具和插头插座标准不像家电那么考究，专门有个22.11的可拆卸部件试验。

还有一个分歧就是，此时是否考虑更换光源时打开产品的情况。如果考虑的话，那么后面的部分就类似COVER；如果不考虑，就只有产品外壳。

以下为IEC60884-1插头插座标准参考。
24.14.1 Verification of the retention of covers or cover-plates
Forces are gradually applied perpendicular to the mounting surface, in such a way that the
resulting force acting on the centre of the covers, cover-plates, or parts of them is
respectively
– 40 N, for covers, cover-plates or parts of them complying with the tests of 24.17 and
24.18, or
– 80 N, for other covers, cover-plates or parts of them.
The force is applied for 1 min. The covers or cover-plates shall not come off.
The test is then repeated on new specimens, the cover or cover-plate being fitted on the wall
after a sheet of hard material, (1 ± 0,1) mm thick, has been fitted around the supporting frame
as shown in figure 31.
NOTE The sheet of hard material is used to simulate wallpaper and may consist of a number of pieces.
After the test, the specimens shall show no damage within the meaning of this standard.
24.14.2 Verification of the removal of covers or cover-plates
A force not exceeding 120 N is gradually applied, perpendicular to the mounting/supporting
surfaces, to covers, cover-plates or parts of them by means of a hook placed in turn in each
of the grooves, holes, spaces or the like, provided for removing them.
The covers or cover-plates shall come off.

直接上照片，不要画这么个图，还不如照片来的清楚

20N when the opening of the cover will give access to basic insulated parts and 80 N when live parts will be accessible

适用的，接到过类似这样产品的欧盟投诉，同样的问题
拉力时灯座被拉出，直接能触及到灯座后面的带电部件
