ASTM E84 (Standard Test Method for Surface Burning Characteristics of Building Materials)

ASTM E84 is a standardized test used to evaluate the surface burning characteristics of building materials. It measures how easily fire spreads on a material's surface and produces smoke. In the test, a sample is exposed to a controlled flame, and results are categorized based on flame spread and smoke development. The ratings help builders and architects choose safer materials for construction, ensuring that buildings meet fire safety codes and protecting occupants from potential fire hazards. This test is crucial for maintaining safety standards in the construction industry.
