IEC 60238 Figure 4 Normal Operation Test Apparatus For Screw-Type Lamp Holder Test

Product information:

Standard: IEC60238:2016Edition 9.1 (2017) figure 4.

Sample and restrictions: Screw-type lamp holder.

Test purpose: Used to determine the stability and mechanical properties of the lamp holder.

Test principle: Mainly used for lamp holders that are used normally for 100 times and should not hinder continued use and should not weaken their anti-electric shock function. The electrical contact parts should not be loose, the connection between the shell and the top cover should not be loose, and the positioning screws of the threaded pipe mouth should not be loose, etc., which will cause harmful consequences.

Input power: AC220V 50Hz 0.75kW
