Other Details

We are one of the leading manufacturers and suppliers of Collapse Tester which are widely used for checking the sturdiness of non-metallic conduits used in electric wiring. For testing the ability of these conduits to bend without deforming in their cross section or reduction in their cross-sectional area is determined by bending a portion of the conduit through an angle of 90° and maintaining it under bent condition for a period 24 hours inside a hot air oven at a temperature of 60 ± 2°C, and consequently passing a barrel shaped go-gauge through it. The gauge shall pass through the bent conduit under its own weight without any restriction.

Technical Specifications

Angle of bending of conduit: 90°
