Purpose - To measure tensile strength of terminal wire at tension
Criteria - Change in electrode material
Testing Procedures
Step 1 -
Leave the test lamp for 2 hrs at 25±2°C, 35~85% R.H. windless environment and then measure the lamp voltage, starting voltage, brightness and chromaticity.
Step 2 -
Apply load weight 8kg in axial direction
Step 3 -
Place the lamp for 2 hrs in 25±2°C windless environment and then measure electrical characteristics, brightness, chromaticity and starting voltage again.
