Guangdong Product Quality Supervision and Inspection Research Institute Light String Winding Test Device DMS-UL

The light string winding test device of Guangdong Product Quality Supervision and Inspection Research Institute mainly assesses whether the sealed light string has sufficient mechanical strength.

Technical parameters of the light string winding test device at Guangdong Product Quality Supervision and Inspection Research Institute:

The qualification of the rigid light string shall be repeatedly tested using each of the following tests in rotation45Next inspection:

a ）60NThe tensile force is not suddenly applied to the end of the pipe, lasting for a period of time1min.

b ）0.15N·mtorque,In an unfavorable direction(Choose selectively when in doubt)Apply non abruptly to the end of the tube,duration1min.(Requires torque equipment to be used in conjunction)

The qualification of flexible light string is determined by the aboveaandbAfter the experiment, the following additional tests will be conducted using this device to verify.

Experiment: Apply60NPull the hose to a diameter of250mmOn the cylinder, the number of winding cycles and the ambient temperature of the test shall be as follows:

—IP20The string of lights 25℃±5℃ 10time

—IP20The above light string 25℃±5℃ 10time

Continuing -15℃±5℃ 10time

Equipment material: formed aluminum material

Round wood diameter:Ø250mm
