Bunched Cable Vertical Flame Spread Testing Machine is designed in accordance with UL1685, GB18380.3 standards for wire and cable burning test requirements. The equipment meets IEC 60332-3-10, KS C IEC 60332-3-21 ~ 25 (A ~ Class D) standards and is used to test the vertical installation of bunched cables or optical cables to suppress flame vertical spreading under specified conditions.

This is essential equipment for power cables, control cables, and fiber optic cable bundle burning tests. When the burner is adjusted to 20 degrees, the tester can achieve IEEE 383 (IEEE 1202) testing standards. The unit can be equipped with a heat release instrument configuration port and, when used with a gas analyzer, can measure thermal power values such as HRR (heat release rate) and SPR (smoke generation rate).
