To be approved at the 49th CTL Plenary Meeting, in 2012
Question:
Consider a gear box of a down light with integrated GX 24 lampholders. In such a gear box the
lampholder housing and lamp retention are both parts of the gear box front. The lampholder contacts are
- s2 x! M$ |3 I" P/ Bthen fitted to the PCB of the electronic ballast.
How do we apply the needle flame test in this case:
2 ^- u$ b. k, r/ z6 \  y- On the PCB only?
- On the complete lampholder, i.e. on the lampholder housing?
Decision:
The needle flame is applied to the parts which retain current carrying parts in position. The surrounding
parts must be kept in place during the tests.
