Household Electrical Appliance Tester Cord Anchorage Strain and Twisting Test

Household Electrical Appliance Tester Cord Anchorage Strain and Twisting Test

  • Model:

Cord Anchorage Strain and Twisting Tester HJ0609




This device is used to check the cord anchorage of the appliances provided with a supply cord, and appliances intended to be permanently connected to fixed wiring by a flexible cord, shall relieve conductors from strain, including twisting, at the terminals and protect the insulation of the conductors from abrasion.

According to the standard Clause 25.15 of IEC 60335-1 Household and similar electrical appliances – Safety – Part 1: General requirements and etc.


Test sample: Household appliances, medical equipment, lamps, plugs and sockets and etc


Feature: The test equipment adopts Z-word structure, can be used to test the clamping terminal firmness of the refrigerators, washing machines and other large household appliances’ power cords.

The test method is that a mark is made on the cord at a distance of approximately 20 mm from the cord anchorage or other suitable point. Then the cord is then pulled, without jerking, for 1 s in the most unfavourable direction with the force specified. The test is carried out 25 times. The cord, unless on an automatic cord reel, is then subjected to a torque that is applied for 1 min. After above test, the cord shall not be longitudinally displaced by more than 2 mm.


Technical parameters:

Power supplyAC 220V 50Hz
Pull Force Weight20N*2,30N*2 (the pulling force of 30N,60N,80N,100N can be achieved)
Torque Weight5N*1, 12.5N*1, 17.5N*1 and a torque arm (0.1Nm,0.25Nm,0.35Nm can be achieved)
Pull Test Cycles0~999999, can be preset, default 25
Pull Speed1 cycles/s
Torque Time0.01S~99 hour 59 min 59 s

Tension fixture and torque fixture are combined, which coordinated in the middle through the bearing, reduce the friction during torque test.

StructureThe device adopts motor cam mandrel mechanism, Z-word connection, so that the fixture can hold the power cord which is on the appliance and 150mm above from the ground.
Temperature Alarm0~200℃ Adjustable
Temperature deviation±0.5℃
Temperature ControlIntelligent control
Temperature DisplayThermometer display
MaterialInside chamber is made of stainless steel and outer chamber is made of electrostatic spraying steel plate
