Cord Anchorage Strain And Twisting Test Equipment HJ0609
Product information:
The test appliance conforms to IEC60335-1:25.15. It is used to test the power cord tension and torque at the terminal two trials of the appliances which are with a power cord, and intended flexible cord permanently connected to the fixed wiring and other household electrical appliances, medical equipment, checking whether the clamping device is secure.
Appliances provided with a supply cord, and appliances intended to be permanently connected to fixed wiring by a flexible cord, shall have a cord anchorage. The cord anchorage shall relieve conductors from strain, including twisting, at the terminals and protect the insulation of the conductors from abrasion.
A mark is made on the cord while it is subjected to the pull force shown in follow table, at a distance of approximately 20 mm from the cord anchorage or other suitable point.
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 as close as possible to the appliance. The torque is specified in following table and is applied for 1 min.
During the tests, the cord shall not be damaged and shall show no appreciable strain at the terminals. The pull force is reapplied and the cord shall not be longitudinally displaced by more than 2 mm.
Technical parameters:
| Power Supply | AC230V, 50HZ |
| Pull force weights | 20N*2, 30N*2( the pulling force of 30N, 60N, 80N, 100N can be achieved) |
| Torque weights | 5N*1, 12.5N*1, 17.5N*1(the torque force 0.1Nm, 0.25Nm, 0.35Nm can be achieved) |
| Test times | 0~9999(selectable),25 times is by default |
| Pull force frequency | 1 times/s |
| Torque arm | 20mm |
| Torque time | 0.01S-99 hours 99 min |
| Clamp | Combined clamp for both pull force and torque, matching by the bearing, can reduce the friction when processing torque test |
Table – Pull force and torque.
Mass of appliance (kg) | Pull force (N) | Torque (Nm) |
≤1 | 30 | 0.1 |
> 1 and ≤4 | 60 | 0.25 |
> 4 | 100 | 0.35 |
Test procedure:
1. Press the “START” button, the pull force testing begins, after it reaches to the preset test times, the torque weight will be released automatically, and then the torque testing begins. After it reaches to the preset twist time, manually lift the torque weight, then the pull force and torque testing is completed.
2. Measure out the distance between the mark and the cord anchorage, the distance subtract 20mm is the pull out length after the test.
3. When process the next test, must press the “RESET” button before starting the test, or the test device will not work.
