Question: - B/ j/ q2 `: ^; B6 k
Some lampholders intended to be built into appliance are of such construction (see the photos below) that it is impossible to test them by use of some gauges, e.g. a gauge according to the standard sheets 7006-30 and 7006-31, and3 j% i1 u! v" a- g' z s' d" ^5 B9 H
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?+ D }4 H# @9 j, @1 O
