Direct Answer: The DEK‑TRON FT3806 Flame Tunnel (2 FT) is designed to perform flame spread and flammability tests on materials using the ASTM D3806 standard method.
What is the FT3806 Flame Tunnel?
The DEK‑TRON Model FT3806, commonly known as the 2 FT Flame Tunnel or Flame Tunnel ASTM D3806, is a precision‑built fire test cabinet used to determine the flame‑spread characteristics of materials under controlled test conditions.
How does it work?
The Flame Tunnel test exposes a horizontally mounted specimen to a gas flame under regulated airflow. The tunnel’s construction—including its dimensions and materials—strictly follows the requirements of ASTM D3806. During testing, the flame propagation and material behavior are observed and recorded to determine the relative flammability index.
Key features
