IEC 60884-1 Figure 20 Rewirable Plugs and Socket-outlets Cord Retention Test Apparatus
Standard: IEC60884-1 clause 23.2 figure 20.
Application: It is used for testing rewirable plugs and rewirable portable socket-outlets shall be provided with a cord anchorage such that the conductors are relieved from strain, including twisting, where they are connected to the terminals and that their covering is protected from abrasion.
Test sample: Rewirable plugs and rewirable portable socket-outlets cords.
Feature: The apparatus conducts automatically after the test started, and it will stop working after reaching the setting number of times.
Technical Parameters:
| Power supply | Match client’s local power supply conditions |
| Number of testing | 1~9999(it is adjustable. Default:100) |
| Rate of testing | 60 times /min |
| Weights | 10N*1, 60N*1, 20N*2 |
| Cord bushes | 5 pieces (each ofΦ6mm,Φ8mm, Φ10mm, Φ12mm, Φ16mm) |
| Working stroke | 35mm |
Test process:
Loose the up cord clamp, select the appropriate cord bush (refer to the table below) according to the specifications of the sample, insert the cord bush into the entrance hole, then the cord of the specimen are across the cord bush, clamped by the up and lower cord clamps. After that, choose the appropriate weight based on the weight of the test requirements, the weights are hanged on the end of the cord, adjust the weight to the appropriate height, and the test can be started.(The clamping position should make the bottom of the weight do not touch the cabinet during working). Shown as below:
