What is the Steiner tunnel test flame spread rating for red oak?

• A. 75
• B. 100
• C. 150
• D. 200

Answer: (B)

The Steiner tunnel test is a widely recognized method used to evaluate the flame spread characteristics of building materials. In this test, materials are subjected to a controlled flame to measure how quickly flames spread across their surface. The results yield a numerical flame spread rating that helps to categorize the material's fire performance. Red oak is commonly referenced in fire safety standards due to its flammability properties. The flame spread rating for red oak specifically is standardized at 100. This rating indicates that red oak has a moderate level of flame spread; it is representative of a material that can ignite and burn relatively quickly when exposed to flame but is less flammable compared to other more hazardous materials. Understanding this rating is essential for fire safety inspections, as it aids in assessing the potential fire hazard of various construction materials and ensuring compliance with safety regulations designed to mitigate fire risks in buildings. In practical terms, materials rated lower than 100 are generally considered to have better fire-resistive properties than those rated higher.
