The Steiner Tunnel Test assesses which characteristic of interior finishes?

The test focuses on how interior finish materials behave when exposed to flame on their surface. It measures surface burning characteristics, specifically how quickly a flame can spread across the material and how much smoke is produced as it burns. In the test, a controlled flame is applied to the material mounted in a tunnel, and instruments quantify the flame spread along the surface and the smoke developed during burning. These results help classify materials for use in walls and ceilings based on their fire performance. It does not assess colorfastness, whether the material stays structurally sound after burning, or the toxicity of the combustion products; those aspects are addressed by other evaluations.
