The test quantifies the flame spread rate, the heat emitted, and the smoke produced by the flooring material. Critical outcomes from ISO 9239 include the critical flux at extinguishment and the smoke development rate, which are essential for assessing the fire safety of flooring materials used in various settings. This information is invaluable for manufacturers, builders, and regulatory bodies to ensure that flooring products are safe for use and meet required fire safety standards, particularly in high-risk environments like public buildings and commercial spaces.
