Diferencias de rendimiento
In distinguishing heavy-duty and medium-duty conduits, their performance under stress is crucial. The AS/NZS 2053.1 standard provides clear guidelines for evaluating conduit performance, particularly in terms of compression resistance, impact strength, and collapse resistance. These tests ensure conduits can withstand the mechanical stresses they may encounter during installation and operation.
- Compression Test
The compression test assesses a conduit’s ability to resist deformation under load. According to AS/NZS 2053.1, conduits are subjected to a uniform load distributed over a defined area. This test ensures the conduit can maintain its shape and protect enclosed cables when exposed to external forces.
Compression Strength Criteria in AS/NZS 2053.1
Conducto | Test Load (N) | Deformation Limit |
HD Rigid Conduit | 1250 N | ≤ 10% deformation |
MD Rigid Conduit | 750 N | ≤ 10% deformation |
HD Corrugated Conduit | 1250 N | ≤ 25% deformation |
MD Corrugated Conduit | 750 N | ≤ 25% deformation |
- Impact Test
The impact test evaluates a conduit’s ability to withstand sudden mechanical shocks, such as drops, collisions, or accidental strikes. And the conduit should show no cracks or disintegration when subjected to the following weight and height. This test is crucial for ensuring the conduit’s integrity during handling and installation.
Hammer Weight and Fall Height in AS/NZS 2053.1
Conduit Duty | Weight of the hammer kg | Fall height mm |
Medio | 2.0 | 100±1 |
Pesado | 2.0 | 300±1 |
- Collapse Test
The collapse test is a critical evaluation method outlined in AS/NZS 2053 standards to ensure conduits maintain their structural integrity under mechanical and environmental stresses. This test assesses whether a conduit can retain its internal diameter and functional shape when exposed to bending forces and prolonged high temperatures.
The process begins by bending the conduit test piece at room temperature through a specific angle, typically 90°, using a bending device with a standardized radius.
Criterios de aceptación: The gauge must pass through the conduit without obstruction or excessive deformation.
Conducto rígido: According to AS/NZS 2053.2, only conduits of diameter less than 32mm and medium, or light duty conduit should be tested for collapse, heavy duty conduits do not need to be tested. When tested with a bending device, the conduit should pass the diameter check.
Corrugated Conduit: All sizes are applicable. (AS/NZS 2053.5)
Peso
Heavy Duty Conduit:
Due to their thicker walls and stronger materials, heavy-duty conduits are heavier than their medium-duty counterparts.
