Clause 25.15 of IEC 60335-1 Household and similar electrical appliances - Safety - Part 1: General requirements and etc.
The power cord tensile and twist test machine features a Z shaped structure. It is used to measure the cord anchorage of appliances with a supply cord. 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.
Medical equipment, household appliances, lamps, plugs and sockets, etc.
|Parameters / Model|
|Input Power||AC220V 50HZ|
|Pull Force Weight||20N*2,30N*2 (the pulling force of 30N,60N,80N,100N can be achieved);|
|Torque Weight||5N*1, 12.5N*1, 17.5N*1 and a torque arm (0.1Nm,0.25Nm,0.35Nm can be acheived);|
|Pull Test Cycles||0~999999, can be preset, default 25|
|Pull Speed||1 cycles/s|
|Torque Time||0.01S~99 hour 59 min 59 s|
|Fixture||Tension fixture and torque fixture are combined, which coordinated in the middle through the bearing, reduce friction during the torque test.|
|Structure||The device adopts a motor cam mandrel mechanism, Z-shaped connection, so that the fixture can hold the power cord which is attached to the appliance and 150mm above from the ground.|
