Description

The hard casing bending test apparatus, designed in accordance with IEC 61386-21:2021 Clause 10.4.102 and Figure 103, is engineered to evaluate the bending performance of non-metallic and composite conduits, including insulating electrical conduits. The test procedure involves inserting a specified bending mandrel into the conduit specimen. The specimen is securely fixed using a forming mold and clamping mechanism. The apparatus then applies controlled bending force to achieve a predetermined angle. Post-test evaluation includes visual inspection for cracks and verification of gauge passage through the conduit under its own weight, thereby assessing structural integrity and bending resistance. The equipment ensures stable, repeatable operation in compliance with international standards, providing objective data for quality assurance of conduit systems.
