GUIDE CABLE TRAYS TECHNICAL
In their cable-carrying role, cable trays also contribute to safety in the event of a fire. There is no international standard on the fire resistance of cable management systems, just local standards.
Fire Resistance Standards for Polyurethane Cable Trays
Polyurethane cable trays can achieve fire resistance ratings up to E90, maintaining circuit integrity for 90 minutes under standardized fire testing conditions.Fire Resistance OverviewPolyurethane cable trays are designed to support electrical cables while providing fire protection and circuit integrity. Fire resistance testing evaluates how well these trays withstand flames, prevent fire spread, and maintain the functionality of critical electrical systems such as emergency lighting, fire alarms, and smoke extractors .Standards and TestingDIN 4102-12: A widely used German standard for fire-resistant cable trays. It requires testing the entire cable tray system, including supports and cables, in an oven at temperatures up to 1000°C for durations of 30, 60, and 90 minutes .E90 Rating: Indicates that the cable tray system can maintain circuit integrity for 90 minutes under fire conditions . This is often the maximum duration tested for compliance with DIN 4102-12.BS EN IEC and Local Standards: In the absence of a European-wide standard, manufacturers may follow local regulations or international guidelines to ensure fire performance .Performance ConsiderationsCircuit Integrity: Fire-resistant trays are tested to ensure that cables continue to function during a fire, which is critical for safety systems.Material Behavior: Polyurethane trays are engineered to resist ignition, limit flame spread, and reduce smoke and toxic gas emissions .System Testing: Fire resistance is evaluated for the complete installation, including trays, supports, and cable types, to simulate real-world conditions .Practical ImplicationsFor installations in industrial, commercial, or public buildings, selecting a polyurethane cable tray with an E90 fire rating ensures that critical circuits remain operational for at least 90 minutes during a fire, providing sufficient time for evacuation and emergency response . Complementary accessories, such as fire-rated cable cleats, are recommended to maintain overall system integrity. In summary, polyurethane cable trays can achieve up to 90 minutes of fire resistance (E90) when tested according to DIN 4102-12 or equivalent standards, making them suitable for high-safety electrical installations.
