提供能够从供给由插头或全极开关的方法分离的工具。然而，插入或移除它们位于可拆卸盖后面的灯的过程中，防止与灯头的带电部件接触应被确保。<br>这不包括使用螺杆型熔断器和螺旋型微型断路器，其是不用工具的辅助下可访问的。<br>图1的试验指施加而没有明显的力，该工具在每一个可能的位置中。<br>通孔，所述试验指施加到任何深度手指将允许，并且它被旋转或在成角度前，和插入之后的任何位置。<br>如果开口不允许手指的进入，对在直位置的手指上的力增大到20 N和与手指弯曲重复该测试。<br>它应不可能与仅用清漆，搪瓷，普通纸，棉，氧化膜，珠或密封剂保护的试验指带电部件或带电部件接触。

provided the tool can be isolated from the supply by means of a plug or an all-pole switch. However, during insertion or removal of lamps which are located behind a detachable cover, protection against contact with live parts of the lamp cap shall be ensured.<br>This excludes the use of screw type fuses and screw-type miniature circuit breakers which are accessible without the aid of a tool.<br>The test finger of Figure 1 is applied without appreciable force, the tool being in every possible position.<br>Through openings, the test finger is applied to any depth that the finger will permit, and it is rotated or angled before, during, and after insertion to any position.<br>If the opening does not allow the entry of the finger, the force on the finger in the straight position is increased to 20 N and the test with the finger bent repeated.<br>It shall not be possible to touch with the test finger live parts or live parts protected only by lacquer, enamel, ordinary paper, cotton, oxide film, beads or sealing compound.

如果工具可以通过插头或全极开关与电源隔离。但是，在插入或拆卸位于可拆卸盖后面的灯具时，应确保防止与灯头的带电部件接触。<br>这不包括使用无需工具即可接近的螺旋式保险丝和螺旋式微型断路器。<br>图1中的试验指在没有明显力的情况下施加，工具处于每个可能的位置。<br>通过开口，将测试指施加到手指允许的任何深度，并在插入任何位置之前、期间和之后旋转或成角度。<br>如果开口不允许手指进入，则手指在直线位置上的力增加到20 N，并重复弯曲手指的试验。<br>不得接触试验手指带电部件或仅由油漆、搪瓷、普通纸、棉花、氧化膜、珠子或密封剂保护的带电部件。<br>
