The Fire-Resistance Cable Burning Test Apparatus (Cable Fire Integrity Tester) is designed to evaluate the ability of mineral-insulated cables and cables with fire-resistant layers to maintain circuit integrity under flame exposure. The apparatus subjects the test sample to a controlled gas flame under specified temperature, time, and electrical loading conditions, monitoring for short circuits or open circuits. This allows assessment of the cable’s fire-resistance performance. The system is suitable for type tests, factory inspections, and research verification of fire-resistant cables.

Applications

Based on practical applications of domestic and international fire-resistant and flame-retardant cable testing equipment, this apparatus is suitable for the following products and scenarios:

Mineral-insulated cables (MI cables)

Power cables with fire-resistant layer structures

Fire-resistant building wires

Low-voltage control and signal cables

Fire-resistant optical fibers and composite cables

Fire-resistant cables rated ≤ 450/750 V

Verification of fire, flame-retardant, and water-resistant fire performance

Applicable users include cable manufacturers, electrical inspection agencies, fire safety product testing centers, research institutes, and third-party laboratories.

Standards

The apparatus is designed to comply with and support the following standards:

GB/T 19216-2008 — Test methods for cable or optical fiber circuit integrity under flame conditions

GB/T 19666-2019 — General requirements for flame-retardant and fire-resistant wires and cables

IEC 60331-2009 — Tests on electric cables under fire conditions

BS 6387 — Performance requirements for maintaining circuit integrity of cables under fire conditions

BS 8491 — Assessment methods for fire-resistance of cables
