IEC 61386-21 Bending Test Apparatus for Rigid, Non-Metallic & Composite Conduits
IEC 61386-21 Figure 103 Bending Apparatus For Non-Metallic And Composite Conduit
Product information:
The Bending Apparatus for Non-Metallic and Composite Conduits is designed for performing 90° bending tests on rigid conduits, non-metallic conduits, composite conduits, and PVC corrugated pipes. It ensures accurate bending performance evaluation according to major international and domestic standards.
This equipment fully complies with JG3050-1998 (Clause 6.6 & Fig. 9), GB 20041.21-2008, GB/T14823.2, ZBG 33008, and IEC 61386-21 clause 10.4.102 & Fig. 103.
It provides standardized bending wheel radii and groove dimensions to meet the specified nominal conduit sizes, ensuring test accuracy and repeatability.
The bending apparatus is widely used by conduit manufacturers, quality inspection centers, research institutes, and certification laboratories.
Features:
✔ Complies with IEC 61386-21, GB 20041.21, JG3050, GB/T14823.2, ZBG33008
✔ Ideal for bending tests of non-metallic, composite, rigid, and PVC corrugated conduits
✔ Standardized 90° bending angle
