Product Description
IEC 60968-figure 3 Test arrangement for bending moment imparted by the lamp at the lampholder
Samples and Restrictions:
Semi-luminaires intended for connection to Edison screw or bayonet lampholders
Application:
It is used to test the bending moment effect of the semi-luminaires on the lampholders, in order to prevent the damage of the lampholders from being damaged by excessive bending moment.
Test Principle:
Using a push-pull force gauge to connect with a semi-luminaire through a flexible cord, the force of the free bending of the luminaire is measured, and the actual bending moment value is calculated by multiplying the force arm, compared with the standard requirement.
Technical Parameters:
| Digital display force gauge | Digital display, force range: 0-100N, resolution 0.1N |
| Measurable length of semi-luminaires | 0-400mm |
