Apparatus For Testing Cord Retention For Flexible Cables Of IEC60884-1 Figure 20 Single Station
Standard:
IEC 60884-1 'Plugs and socket-outlets for household and similar purposes – Part 1: General requirements' clause 23.2, figure 20
Application:
It is 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. The machine conducts automatically after the test started, it will stop working after reaching the setting number of times.
Test sample:
Non-rewirable plug and socket-outlet, rewirable plug and socket-outlet.
Parameters:
| Power supply | AC 220V 50Hz |
| Weights | 10N*1, 60N*1, 20N*2 |
| Rate of testing | 60 times / min |
| Test times | 0-9999, preset. Default 100 times. |
| Cord bushes | 5 pieces (Φ6mm,Φ8mm, Φ10mm, Φ12mm, Φ16mm) |
| Working stroke | 35mm |
The pull force to the flexible cable:
| The rated current of the flexible cable(A) | The rated voltage of the flexible cable(V) | The tensile force |
| 2.5 | — | 50 |
| 2.5～16 | <250 | 60 |
| 2.5～16 | >250 | 80 |
| >16 | — | 100 |
