ASTM E94

ASTM E84, formerly known as ASTM E94, is a standardized test that measures how much a material resists how quickly fire spreads across its surface. It assesses a material's flame spread and smoke development when exposed to a controlled flame in a test chamber. The results help determine the material's suitability for use in buildings, ensuring safety by identifying materials that may contribute to the rapid growth of fire or smoke. This testing is crucial for building codes and safety regulations, guiding designers and builders in choosing compliant, fire-resistive materials.
