Brannklassifisert

Brannklassifisert is a term used to describe a material, product, or assembly that has been tested for fire performance and assigned a fire classification. It is commonly used in construction, interior fit-out, and product labeling to indicate how a material behaves in a fire.

Classification systems: In Europe the main standard for reaction to fire is EN 13501-1, which yields classes from A1 (non-combustible) to F (unclassified), often with suffixes such as s1, s2, or s3 for smoke production and d0, d1, or d2 for flaming droplets. For fire resistance of building elements, standards like EN 13501-2 and related EN test methods define how long a component can maintain structural integrity and insulation under fire (for example, EI 30, EI 60). The term brannklassifisert can apply to individual products (insulation, boards, cladding), to assemblies (walls, floors, ceilings), or to complete systems (facades, partitions).

Certification process: Fire classification relies on standardized tests conducted in accredited laboratories. Results are documented in a Declaration of Performance (DoP) under the EU Construction Products Regulation (CPR). In Norway and other EEA countries, products marketed with a fire classification typically carry DoP labeling or other documentation that communicates the relevant fire classes.

Practical use: Designers, contractors, and building authorities use fire classifications to select materials that meet local safety requirements. Choices depend on intended use, required fire compartmentation, evacuation plans, and regulatory demands for façades, interior finishes, and structural components.

Limitations: A brannklassifisert label reflects performance under specific test conditions and does not guarantee identical behavior in all real-world scenarios. Proper installation, maintenance, and the integrity of assemblies are essential.
