Bunched Cable Vertical Flame Spread Tester QualiFlame-BCVFST

Bunched Cable Vertical Flame Spread Tester QualiFlame-BCVFST evaluates how flames spread vertically across grouped cables arranged on a ladder, providing insight into their fire resistance.

Burning Behavior of Bunched Cables

1. The stainless steel test chamber has inner dimensions of 1000mm × 2000mm × 4000mm. The chamber walls are lined with 65mm of mineral wool for thermal insulation.
2. The bottom of the chamber is elevated above the ground, featuring an 800mm × 400mm air inlet positioned 150mm from the front wall, with a grill placed above.
3. A 300mm × 1000mm exhaust opening at the top allows for gas removal during testing.
4. A high-temperature resistant observation window is installed on the front door and side panel for monitoring during testing.
5. Equipped with OMEGA K-type insulated thermocouples for measuring chamber temperature.
6. The chamber air supply system consists of a blower, inverter, stainless steel U-shaped tube, and an anemometer.
7. Constructed with a stainless steel tubular ladder, available in 500mm and 800mm widths.
8. Includes an AGF ribbon-type propane gas burner with a venturi mixer.
9. Two propane and air mass flow controllers ensure a standard burning flame with an accuracy of ±1%
