    Description

    The IEC 61386-21:2021 Clause 10.4.102 and Figure 103 bending test apparatus is engineered for evaluating the bending performance of non-metallic and composite conduits, including insulating electrical conduit systems. Prior to testing, a specialized bending aid is inserted into the specimen. The specimen is secured through the coordinated action of the forming mold and clamping mechanisms. The apparatus’s bending mechanism applies controlled force to achieve the specified bending angle. Following the test procedure, the specimen undergoes visual inspection for surface cracks, and the free passage of a designated gauge through the conduit under gravitational force is verified. This methodology assesses the structural integrity and mechanical withstand capability of conduit systems under bending stress conditions. The equipment operates in strict compliance with regulatory requirements, delivering stable and repeatable bending processes that provide objective data for quality assurance of conduit products.
