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

Technical parameters:

Control system	PLC control, touch screen operation
Drive mode	Servo motor + transmission mechanism
Test station	Single station
Test item	Normal screw-in and screw-out test, screw out when the set torque value is reached
Fixture	The test lamp cap and lamp holder are clamped by chuck
Number of trials	0-999999, default 100 times
Test speed	15 times/minute
Torque	0.4, 1, 1.5, 3N.m, control servo motor output, torque sensor monitoring Torque sensor range 10N.m
