IEC 60332-3 Burning Behaviour of Bunched Cables Tester

Introduction

Bunched Cable Vertical Flame Spread Tester is used for bundle cable or fiber optic cable to detect vertically mounted under specified conditions for vertical flame spread inhibiting the ability of the instrument.

When given a certain amount of housing supply of gas and the use of standardignition source of ignition, this instrument can be used to test for verticalflame vertical flame vertical diffusion to electric cables and wires of state.

In addition, if the tester burner adjustment of 20 degrees can be achieved byIEEE 383 (IEEE 1202) testing standards. Equipment can be equipped with heatrelease instrument configure the port, with the gas analyzer can measure thethermal power values such as HRR (heat release rate), SPR (smoke generationrate) and so on.
