EN 13501
EN 13501 is a European standard that classifies the fire performance of building materials and construction elements. It assesses how materials react to fire, including how quickly they ignite, the spread of flames, heat release, and smoke production. The standard assigns ratings such as A1 (non-combustible) or B, C, D, E, and F (varying degrees of fire hazards), helping architects and builders select appropriate materials to ensure safety. Essentially, it provides a consistent way to evaluate and compare the fire safety features of building components across projects and regions.
