Which test rates the surface burning characteristics of interior finishes and other building materials?

The Steiner Tunnel Test is specifically designed to evaluate the surface burning characteristics of interior finishes and other building materials. This test involves placing the material in a controlled environment where it is exposed to flame, and it measures how far flames travel along the surface of the material over a specified timeframe. The results are quantified to produce a Flame Spread Index, which provides a standard measure to compare the performance of different materials regarding their flammability.

This testing method is essential for ensuring safety in building design, as it helps architects and builders select appropriate materials that minimize the risk of fire spread in interior spaces. It is widely recognized in building codes and standards, making it a critical component in the assessment of materials used in construction.
