CTL56 - Burning Behaviour Test Apparatus - VDI Method

Determines whether a fire will propagate in a dust layer once started by an external ignition source.


  • Digital LED display of current flowing through the platinum wire
  • Front panel fine adjustment of current flowing through the wire
  • Timer cut-out incorporated - safety feature to power down the control unit if left on for ca 7 minutes
  • Easy platinum wire change facility (repeatable method assuring the wire length is maintained when the wire is changed)

Burning Behaviour Test Apparatus

The Chilworth Technology Burning Behaviour unit is based on VDI 2263. It determines if, and to what degree, a fire will propagate in a dust-layer once started by an outside source. The result is either given by a "combustion number" or the rate of propagation of the fire. The test equipment comprises a quartz plate, electrically heated glowing platinum wire at approx. 1000 °C (diameter: 1 mm, length 86 mm, current 30 A). A drying oven is also required for this test but not supplied as standard (see options overleaf).

Functional Specification & Deliverables

  • 1 x platinum hot coil current control unit
  • 1 x heater power handset (pre-wired into the control unit)
  • 1 x insulating block
  • 1 x glass tube
  • 1 x 100 mm length of platinum wire
  • 100 - 200 V / 220 - 240 V - 6 A input
  • Fine coil output current control (optimum 29 to 31 A. Control derived from low voltage d.c output)
  • 1 x instruction manual

Optional Extras

  • Spare platinum wire
