IEC 60598-2 Lampholder Copper Contacts Security Thrust Test Device For LED Test
Applied Standards For Lampholder Copper Contacts Security Thrust Test Device:
The test device is conformed to the IEC60598-2-20 clause 20.12.4, Fig 2.
Test Principle For Lampholder Copper Contacts Security Thrust Test Device:
It is used to check security of lampholder contacts, avoid the lamp holder contacts shifting and the live parts of the lamp string becoming accessible which are caused by the frictions.
Test method is: The incandescent lamp is removed and a force of 15 N is applied for 1 min to each of the conductors connected. Following this, a force of 30 N is applied for 1 min to the two conductors together. The forces are applied at a distance of 3 ± 0,8 mm from the insertion points in the lampholder so as to try to move the contacts from the lampholders. During the test the contacts shall not move more than 0.8 mm.
