Equipment Description
The system consists of an adjustable test platform, non-combustible panel assembly, gas burner, supply fan with air channel, isolation plate, and fire panels. Tests must be conducted in a controlled environment (10-32°C) with all openings closed to prevent external interference.
Before testing, mortar should fill gaps between roof covering material and frame to prevent air/flame passage. Airflow must be calibrated using 1m×1.3m plywood at specified inclination (127mm/300mm).
