EN 13501-2 is a harmonised European standard. It provides the methodology for classifying building elements based on their fire resistance performance. Unlike reaction-to-fire standards (which measure how a material contributes to a fire's growth), fire resistance measures how well an assembly or element can contain a fire and maintain its structural integrity.
