Protection of installations against thermal effects caused by fire.

IEC 60364-4-42 Cable Fire, Arc Fault and Heat Spreading Barriers

Elektrik tesisatı kaynaklı yangınlar tüm yapı yangınlarının %25’inden fazlasını oluşturur. Kablolarınızın izolasyonu eridğinde duvar içinden yayılan sessiz bir alev tüm katı sardığında müdahale için çok geç kalınır.

Fire starts with electricity, it spreads through the cable.

IEC 60364-4-42 defines the protective measures that must be taken to prevent an electrical fault from turning into a fire. Loose connections, overloaded cables, and arc faults (series/parallel) are invisible sources of fire.

AES Innovation's thermal camera scans image abnormal heating (hot spots) at panel and cable tray connection points with millimeter precision, identifying sources of faults before they escalate into fires. Areas such as behind suspended ceilings, cable shafts, and internal panel connections are particularly critical focus points.

Fire Risk Analysis and Thermal Mapping

Our Thermal Protection Audit:

  • Panel Internal Connection Thermography:
    Dangerous temperature increases caused by overcurrent loads at the terminal clamping points of all switchgear (switches, contactors, busbars) are mapped using an infrared camera.
  • Cable Penetration Fire Barrier Inspection:
    The presence and integrity of firestop materials, which prevent the spread of fire at points where cables penetrate the floor slab or fire compartment wall, are checked.
  • 300mA Fire Protection RCD Test:
    The 300mA RCD (fire protection relay) located at the main entrance of the entire building is verified by periodic trip tests to detect ground leaks and interrupt the circuit before a fire occurs.
  • Arc Fault Detection (AFDD) Assessment:
    The ability of arc fault detection devices (AFDs), recommended for modern installations, to detect serial arc faults is evaluated.

If you want to prevent the fire, not put it out

By the time the fire department arrives, it's already too late. AES Innovation's thermography and verification services provide engineering evidence that prevents both loss of life and property by capturing the 'root cause' of the fire at the spark stage.

International Standards and Related Legislation

IEC 60364-4-42:2024 (Protection against thermal effects) and, consequently, IEC 60364-5-52 (Cable selection) are implemented within the framework of the Regulation on Fire Protection of Buildings (BYKHY).

Frequently Asked Questions

FAQs for building managers and fire safety professionals.

AES thermal reports are recommended once a year for high-load industrial facilities and every six months for critical infrastructure (hospitals, data centers). Insurance companies accept AES thermal reports as proof of fire risk reduction.

IEC 60364-4-42 defines this as part of electrical verification. The risk of fire spread at cable penetration points is one of the items that must be inspected as part of independent periodic inspections and visual inspections.
