Computer Control Bunched Cable Vertical Flammability Testing
Apparatus for UL1685
Bunched Cable Vertical Flame Spread Testing Machine is designed
accordance with the relevant provisions of UL1685,GB18380.3
standard about wire and cable burning test requirements. And meet
with IEC 60332-3-10, KS C IEC 60332-3-21 ~ 25 (A ~ Class D)
Bunched Cable Vertical Flame Spread Tester is an equipment which
used to test the vertical installation of a bunched cable or
optical cable to suppress the flame vertical spreading under the
specified conditions, is the necessary equipment for power cables,
control cables and fiber optic cable bundle burning test.In
addition,if the tester burner adjust of 20 degrees,it can be
achieved by IEEE 383 (IEEE 1202) testing standards.This tester can
be equipped with heat release instrument configure port, with the
gas analyzer can measure the thermal power values such as HRR (heat
release rate), SPR (smoke generation rate) and so on.
