5 H9 a. Q; x  F4 vthe 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?
Decision:
Lampholder for specific use shall be tested according to the intended use.
