according to Figure 11, if a lampholder is not re-assembled prior to test. This means that the metal part of a lampholder, intended to fix it in the appliance, has to be removed and consequently a lampholder becomes useless. When testing the protection against electric shock with gauge 7006-31 on the re-assembled lampholder, the test probe easily reaches a contact. However, in real situation, a contact with a lamp cap when inserting the lamp is not possible. What is the opinion of other Laboratories?0 q1 ~8 G# u3 I0 D! n: W
