IEC 61386-1:2017 Clause 10.2 Conduit Compression Resistance Tester
IEC 61386-1:2017 Clause 10.2 Conduit Compression Resistance Tester
Product information:
Applicable Standards: IEC 61386-1:2017 Conduit systems for cable management – Part 1: General requirements> Clause 10.2
Specimens & Scope: Suitable for metal, non-metallic and composite conduits used to protect and manage insulated wires and/or cables for electrical or communication systems up to AC 1000 V and/or DC 1500 V.
Test Purpose: To evaluate whether the mechanical performance of conduits after compression meets the standard requirements.
Test Principle:
A PLC control system drives the motor to apply force via a sensor. The sensor is connected to a steel block of (50 ± 0.5) × 50 mm.
The specified force is applied to the specimen within (30 ± 3) s and maintained for (60 ± 2) s. The outer diameter of the specimen is measured during loading, and the deformation shall not exceed 25% of the original outer diameter.
After unloading, the device automatically returns. After (60 ± 2) s, the outer diameter is measured again, and the deformation shall not exceed 10% of the original outer diameter.
