The International Electrotechnical Commission (IEC) provides detailed guidelines for cable tray systems under IEC 61537. This standard outlines the construction requirements, testing methods, and performance parameters for cable trays and related support systems. 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. Cable trays play a crucial role in ensuring the safety and efficiency of electrical and communication systems. 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. The bearing capacity is the most basic testing item for the quality of the cable tray.
