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. A properly designed and installed cable tray system provides outstanding reliability for a facility's control, communication, data, instrumentation and power systems cabling and wiring. For proper installation, design, and maintenance, adherence to international standards is essential.
