Audited Supplier The Bunch Cable burning Testing Machine is conformance to UL1685 and several standards,The vertical burning tester for wire and cable bundles is designed according to the relevant provisions of the UL1685 and GB18380.31 standards for wire and cable bundle burning tests. It also complies with IEC 60332-3-10, KS CIEC 60332-3-21~25 (Class A~D) standards. When a certain amount of gas is supplied to the box and ignited using a standard ignition source, this instrument can be used to test the vertical flame spread to the vertical cable and wire state. In addition, if the burner of this tester is adjusted by 20 degrees, it can meet the IEEE 383 (IEEE 1202) test standard. If a heat release instrument is attached, it can also measure dynamic values such as H.R.R
(heat release rate), S.P.R (smoke generation rate), etc.
The heat release test system is completely based on GBT31248-2014 and EN50399:2011 standards. It adds heat release test smoke pipes, air intake pipes and fans on the basis of GB18380.31 bundled combustion test furnace. It can test the combustion heat release performance of wires and cables.
