Description

Purpose
  • Determine the performance of roof constructions when exposed to external fire (Test method 4 according to DIN CEN/TS 1187).


Standards and test principle
  • Two-stage method combining burning brands, wind and supplementary radiant heat to assess ignition, fire penetration, flame spread and falling/burning debris in realistic conditions.


Sample holder and dimensions
  • Supports representative roof samples in a frame of 840 x 840 mm.
  • Tilt-adjustable sample holder to test specified roof pitches.
  • Radiant plate mounted on a solid steel frame with an integrated joint for easy movement between calibration and test positions.


Two-stage test procedure
  • Preliminary Test (stage 1): checks ignition by simulated incendiary devices (burning brands) without thermal radiation.
  • Burn-Through Test (stage 2): adds wind (internal fan) and radiant heat (radiant panel) to evaluate burn-through, flame behaviour and material fall-off under realistic exposure.


Main components
  • Movable stainless-steel sample frame with removal rails and tiltable cover with observation window.
  • Radiant heater panel assembly: four 300 x 300 mm heater panels, up to 900°C, 45° rotating frame, calibration and test positions.
  • Fire simulation burners with lance, pressure regulator and gas hose (city gas supply).
  • Built-in fan for wind simulation and gas supply system controlled via measurement and control unit.
  • Measurement and control unit with touch panel; individual manual control of components; calibration tools included.


Applications
  • Classification and assessment of roof fire performance: ignition propensity, flame duration, time and type of penetration, and extent of burning or falling material.
