Product Introduction

The IEC 60332-3-10 bunched wire and cable combustion tester is a professional equipment that complies with international standards and is used to evaluate the flame spread performance of vertically installed bunched cables under fire conditions. The tester adopts a 1 m × 2 m × 4 m stainless steel testing room, equipped with a 70 kW belt propane burner and a standard ladder (500 mm or 800 mm wide), simulating real fire scenarios through precise gas flow control. The test content includes igniting for 20 or 40 minutes, measuring the flame spread distance (usually ≤ 2.5 m), suitable for power cables, control cables, and fiber optic cables, widely used in buildings, tunnels, ships, railways, and other scenarios. Complies with international standards such as IEC 60332-3 series, EN 50399, UL 1685, IEEE 1202, and IMO FTP Code Part 5 to ensure the fire safety performance of cables

Application

Power cables: used for power transmission in high-rise buildings, tunnels, subways, power transmission and distribution networks, and industrial facilities.

Control cables: used for control and monitoring of industrial automation systems, data centers, and building signal transmission.

Fiber optic cables: used for telecommunication networks, Internet data transmission, and railway communication systems.

These cables are installed in bundles and are widely used in high-rise buildings, tunnels, subways, ships, railways, data centers, and other scenarios that require high fire safety.


Standard

IEC 60332-3-10: Specifies the vertical flame spread test equipment for bundled cables, including a test chamber, a 70 kW propane burner and a ladder to evaluate the fire resistance of cables.

EN 50399: Based on IEC 60332-3-10 equipment, 20 minutes ignition, test flame spread and dripping, in line with EU building cable standards.

UL 1685: Vertical tray test, 20 minutes ignition, flame spread ≤ 1.5 m (FT4) or ≤ 2.4 m, suitable for North American building cables.

Performance characteristics

1. The dimensions of the stainless steel test chamber are 1,000±100(W) x 2,000±100(D) x 4,000±100(H) mm;

2. The interior surface of the chamber is lined with insulating material;

3. The lower front half of the chamber has an 800±20(W) [insulation/temperature range]. 4. A 300±30 (W)×1,000±100 (D) exhaust port is provided on the top of the chamber for easy removal of flue gas during testing;

5. A flame stop tube is installed to prevent propane gas backfire, thus maximizing sample safety;

6. All control and testing conditions are automatically recorded by computer;

7. Due to the influence of temperature on gas pressure and density, an automatic compensation system for burner fuel gas and air is implemented via computer control;

8. Chamber observation window: fire-resistant glass (5mm thick);

9. Test steel ladder dimensions (vertical): 500 (W)×3,500 (H);

10. Wide steel ladder dimensions: 800 (W) ×3,500 (H);

11. Combustion surface dimensions: (L)257×(W) 4.5 mm;

12. The heat source is a strip-type propane burner torch equipped with a Venturi mixer, with a hole center distance of 3.2 mm.
