Introduction
Bunched cable vertical flammability tester is designed according to relevant regulations such as UL1685, GB/T 18380.31 standards for wires and cables. It also complies with IEC 60332-3-10, BS EN 50399,KS C IEC 60332-3-21~25 (A~D category) standards.
When a certain amount of gas is supplied to the chamber and a standard ignition source is used for ignition, this instrument can be used to test the ability of vertically installed bundles of wires and cables or optical cables to inhibit the vertical spread of flames under the conditions specified in the standard.
In addition, if the burner of this tester is adjusted to 20 degrees, it can also make the test according to IEEE 383 (IEEE 1202) standard (Note: the combustion box is different).
If a heat release instrument is attached, it can also measure power values, such as H.R.R(heat release rate), S.P.R (smoke generation rate), etc.
