What is the official name of the test used to rate flame spread?

• A. Steiner Flame Test
• B. Tunnel Fire Test
• C. Steiner Tunnel Test
• D. Flame Spread Test

Answer: (C)

The main idea is recognizing the official name of the standard test used to rate how quickly a material’s surface flame spreads. The official designation is the Steiner Tunnel Test. In this test, a material sample is mounted in a long tunnel furnace and exposed to a controlled flame at one end; the progression of the flame along the sample is measured to produce a flame-spread rating. This method is the standardized way building codes and fire safety standards compare materials for interior use. The other terms are not the recognized official name for this test; they’re generic or incorrect references for flame-spread testing.
