IEC 60332-3 Wire and cable bunched combustion tester

Introduction:

This tester is designed according to UL1685,GB18380.3 standard and other related regulations.And conform to IEC 60332-3-10,KS C IEC 60332-3-21~25 (category A~D) standards.Bunched wire and cable combustion tester is used to test the ability of vertically installed bunched cable or optical cable to suppress the vertical flame spread under specified conditions.When a certain amount of gas is supplied to the box and a standard ignition source is used, the instrument can be used to test the state of vertical flame diffusion to electric vertical flame vertical cables and wires.In addition, if the burner of this tester is adjusted 20 degrees, it can meet the test standard of IEEE 383.The equipment can be equipped with a heat release instrument and equipped with a gas analysis device to measure the thermal power value, such as H.R.R,S.P.R, etc
