Test device suitable for checking security of lampholder contacts (Model:SFT S2-1204)
Application
The device is used to check security of lampholder contacts, and conformto the IEC60598-2-20 Fig 2.
ConformsTo
IEC60598-2-20 clause 20.12.4 Fig 2
Specifications
Lampholder contacts in push-in lampholders shall be reliably secured inthe lampholder body by means other than friction to avoid a displacement of thelampholder contacts such that live parts of the chain become accessible eitherthrough the bottom or top of the lampholder.
NOTE :An example of an adequate securing method is by the provision ofears on the contacts of the lampholder.
Compliance is checked by inspection and by the following test.
Six lampholders are heated for 7 h according to the requirements ofClause 12.3 of Section 12 of IEC60598-1 in an orientation to reach the highesttemperature. After the lampholders have cooled down to room temperature, thelamps are removed and a force of 15 N is applied for 1 min to each of theconductors connected. Following this, a force of 30 N is applied for 1 min tothe two conductors together. The forces are applied at a distance of 3 mm ± 0,8mm from the insertion points in the lampholder so as to try to move thecontacts from the lampholders.
During the test the contacts shall not move more than 0,8 mm. An exampleof a device suitable
for this test is shown in Figure 2.
