Question:
. @& @: t5 ~7 Q& I1 S* t: {Some lampholders intended to be built into appliance are of such construction (see the photos below) that
0 F# F8 y. F/ e, S5 git 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 according to Figure 11, if a lampholder is not re-assembled prior to test. This means that
+ {" r* a% C3 J% f, ]" h. lthe metal part of a lampholder, intended to fix it in the appliance, has to be removed and consequently a
$ R- R9 h: ^# v* Klampholder becomes useless. When testing the protection against electric shock with gauge 7006-31 on
$ }- l) V% Z, Mthe 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.
