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, and* G; p5 y. o1 j* t0 ~% _
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?  f/ j* o* P; ]6 o0 n( H) A
