Unlike EN 13501-1, which evaluates a material's "reaction to fire" (how a material contributes to the growth of a fire), Part 2 evaluates "fire resistance." Fire resistance measures how well an assembled building element (like a wall, door, or beam) can contain a fire, retain its structural integrity, and prevent thermal transmission for a specified duration. Core Performance Criteria
Load-bearing walls, floors, and roofs.
It does not dictate how a test is performed (that is left to standards like EN 1363-1), but rather explains how to interpret the test data to assign a classification. The standard breaks down performance into specific criteria:
Closures designed to protect openings in fire-rated walls must meet rigorous criteria. Classified under the EI1cap E cap I sub 1 EI2cap E cap I sub 2 categories depending on thermal insulation levels.

The standard, titled "Fire classification of construction products and building elements — Part 2: Classification using data from fire resistance and/or smoke control tests, excluding ventilation services," is the definitive European framework for evaluating how building components perform when exposed to fire.
