Standard:
Clause 25.15 of IEC 60335-1 Household and similar electrical appliances - Safety - Part 1: General requirements and etc.
Application:
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.
Test sample:
Medical equipment, household appliances, lamps, plugs and sockets, etc.
Parameters:
| 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. |
