Product Overview
The Flexible Cord Torsion Test Apparatus (Model SC-A23) is designed and manufactured in accordance with GB/T 2099.1 (GB 2099-2008) / IEC 60884-1, Clause 23.2, Figure 16 and Table 18. It is used to verify that the flexible cable of plugs, portable socket-outlets, fixed parts provided with a flexible cable and their connections, protected by a sheath, is not subjected to excessive stress including torsion at the terminals or ends of the conductors.
Main Technical Parameters

| Torsion disc diameter | 100 mm |
| Weights supplied | 2 N, 3 N, 5 N, 7 N, 8.5 N (one each) |
| Corresponding torque | 0.10 / 0.15 / 0.25 / 0.35 / 0.425 N·m |
| Flexible cable cross-section | 0.5 ~ 1.5 mm² (per Table 18) |
| Construction | Bench-top: aluminium base + adjustable clamping column + stainless steel rotating torsion disc + multi-groove pulley + hook weight set + spirit level |
Construction & Test Method
The apparatus consists of a torsion disc (Ø100 mm), a set of weights (2 N / 3 N / 5 N / 7 N / 8.5 N) and clamping / loading mechanisms. During the test the cable anchorage of the sample is clamped on the torsion disc, and the weight specified in Table 18 is applied at the conductor terminals / ends so that the cable is subjected to the required torsion moment; the sheath and anchorage are then checked for damage, looseness or displacement.
Standards & Subjects
Suitable for power cords and cables of household appliances or similar purposes; torsion / pull tests on the cable anchorage of plugs, portable socket-outlets and fixed parts provided with a flexible cable.
