Test chamber & ventilation

  • All-stainless enclosure with heat-resistant glazed doors at front and at least one side for observation. Free ventilation through a square-box base (stainless, 50 mm high, 25 × 25 mm open grid); chamber stands on 40 mm supports to maintain lateral gaps. Chimney air velocity set and verifiable at 0.7 ± 0.1 m/s (burner lit, hood “on”), measured on central axis. Top outlet under an external extraction hood; include a thermal anemometer (±0.1 m/s) and a readout port.
  • Chimney/outlet sized to accept a φ150 mm (≈ 150 mm) exhaust interface or reducer as required by your lab hood. (ISO gives the required velocity target—keep duct geometry that achieves 0.7 ± 0.1 m/s with your hood.)

Note: Some rail labs use a larger cabinet for DIN 54837; offer an optional large chamber kit (e.g., ~1350 × 800 × 800 mm internal) with bottom stainless grid (typ. 30 × 30 mm, ~30 mm high) and front observation windows to run DIN 54837 without a second instrument.

Burner & gas system

  • Copper burner per ISO drawings; operates at 90° (vertical) and 45°; mounted on a horizontal sliding rail along the chamber centerline for smooth in/out positioning. Fine needle valve for precise flame height.
  • Fuel: commercial propane, ≥ 95 % purity; for stable 45° operation maintain supply 10–50 kPa at the burner.
  • Flame-height verification device set to 20 mm (to yellow tip), ±0.1 mm gauge tolerance. Include burner spacer for edge-impingement (16 mm) and a 5 mm gap gauge between burner lip and specimen surface.

Fixtures, measuring & accessories

  • Specimen holders: two stainless U-frames, 5 ± 1 mm thick, clamped to prevent warping; hanging support keeps underside exposed centrally for edge or surface impingement.
  • Template for cutting/verification: 250 × 90 mm metal plate. Timing device accurate to ≤ 5 s in 1 h resolution to 1 s.
  • Filter paper & tray below specimen for flaming droplets/particles: paper 75 ± 15 g/m², ash < 0.1 %; tray 100 × 50 × 10 mm.
  • Flame position gauge for rapid switching between 45° (surface/edge impingement) and 90° (edge) positions, with fixed datum points.

Specimen & exposure (ISO 11925-2 references for setup)

  • Typical specimen dimensions: 250 ± 2 mm × 90 ± 2 mm; thickness up to 60 mm (thicker products are reduced to 60 mm without exposing the cut face to the flame).
  • Two exposure modes (lab procedure dependent on classification target): edge and surface; common set-ups use 20 mm flame, impingement either 40 mm above bottom edge (surface) or on edge per standard figures; exposure 15 s or 30 s per the classification path; observe flame spread for 20 s or 60 s.

Added compliance kits / mappings

  • EN 13501-1 classification mapping: This apparatus provides the EN ISO 11925-2 part of Euroclass determination (e.g., for Class E / Efl; d-rating relates to paper ignition/flaming droplets in the 11925-2 test).
  • EN 45545-2 (rail): Supports the small-flame ignitability checks used in material sets; where applicable, acceptance often includes flame spread < 150 mm within 60 s and no flaming droplets—verify per the targeted R-requirement/HL level. DIN 54837 (rail): Provide large-chamber option, airflow measurement, drip/particle collection, and wide-mouth burner rail; bottom stainless grid ventilation as above.
  • DIN 4102-1 (building): Offer Brennkasten accessory kit with dedicated sample frames and small-burner geometry to run B-class small-flame tests (typical sample formats 190 × 90 mm for edge, 230 × 90 mm for surface; 20 mm flame, 15 s application—follow DIN 4102-1 method tables

Convenience & safety features (recommended)

  • Dual high-temperature glass viewing panels (front & side) with interlocked door switch to close gas when open.
  • External pusher/handle for burner carriage (keeps operator outside door plane).
  • Scale rail with 1 mm graduations for burner/specimen positioning repeatability. Integrated manometer/regulator set and quick-connect for propane; leak-check port.
  • Digital timer with start/stop paddles; laser pointer or etched marks for 40 mm surface ignition point.
  • Filter-paper cassette for quick change; drip tray under grid.
  • Calibration kit: flame-height gauge, 5 mm distance gauge, 16 mm spacer, chimney anemometer.

Documentation pack: checklists for daily flame-height check, chimney velocity log (0.7 ± 0.1 m/s), and test report templates aligned to ISO 11925-2 figures and EN 13501-1 fields.
