Burning Behaviour of Bunched Cables

  • EN 50399
  • , IEC 60332-3-21~25
The Burning Behaviour of Bunched Cables Test Apparatus is used to evaluate vertical flame spread, heat dissipation, and smoke generation from bundled wires or cables (electrical or optical cables) installed vertically under specified conditions. This is the main test procedure for cable classification in standard EN 13501-6 and has been mandated as a requirement of the European Commission decision. The EN 50399 test equipment is based on IEC 60332-3 and adds exothermic measurement, flue gas density measurement, and an improved air intake system.
Burning Behaviour of Bunched Cables

Features

  • ​The test chamber has an inner dimension of 1,000±100(W) x 2,000±100(D) x 4,000±100(H) mm. The bottom surface of the test chamber is higher than the ground while the rear side is supplemented with insulated material to insulate it from heat.
  • At the lower section of the test chamber, there is a 800±20(W) x 400±10(D) sized hole at the 150±10mm position from the front side of the chamber to supply the air.
  • ​There is a 300±30(W)x1,000±100(D) sized exhaust hole at the rear corner of the top section of the test chamber to allow emission of the smoke during the test.
  • ​A flame trap is installed at the front side of the burner of the vertical flame spread tester to prevent backfire by propane to ensure the utmost safety.
  • ​The vertical flame spread apparatus records all control and test conditions with the computer system.
  • ​Equipped with water spray system for extinguishing, in case of the excessive combustion test occur.
  • ​​Standard and wide stainless steel ladder provided. 
  • ​Two sets of standard propane burner(from AGF) and venturi mixtures.
  • ​Exhaust system consists of smoke collection hood, exhaust duct, air inlet system, centrifugal fan and frequency converter.
  • ​The duct section houses all gas sampling probes, temperature and mass flow probes and has ports for the smoke measuring system.
  • ​Paramagnetic oxygen analyzer, using the method of paramagnetic change to measure the concentration of oxygen in the gas. Concentration range of 0-25%.
  • ​Carbon dioxide analyzer (infrared) for use in heat release measurement. Concentration range of 0-10%.
  • Soot filter, cold trap, drying column, pump and waste regulators for conditioning the sample gases prior to analysis.
  • ​Data acquisition system and user friendly operating software.
