Cable tray/protective casings are to be assigned with a safe Working Load. The test should be performed according to IEC 60068-2-75:2014 pendulum hammer. (Refer the sketch shown below) The test should be carried out on samples of cable tray lengths or cable ladder. Cable tray load testing ensures your trays can hold the weight without bending or breaking. This is critical for safety, ensuring your electrical and data cabling systems. In the context of IEC 61537, “load-bearing” is formally referred to as SWL, which stands for “Safe Working Load. The standard requires that load-bearing tests be conducted with a UDL, meaning the load. The bearing capacity is the most basic testing item for the quality of the cable tray. The safe workload (SWL) is a load [kg/m] that creates a deflection of 1/100 in the span, or if a 1/100 deflection is not achieved, it is the force that creates. This international standard outlines the requirements and tests for cable tray systems used for electrical installations.
