Overview

EN 13501-2:2023/FprA1, developed by CEN, specifies the procedures for the fire classification of construction products and building elements using test data from fire resistance and/or smoke control tests. This European Standard covers a broad range of construction elements, including loadbearing and non-loadbearing components, and products/systems for fire protection. It excludes ventilation services but includes procedures for extended application of test results, ensuring harmonized fire safety across the built environment.

This standard is fundamental for manufacturers, designers, builders, and regulators seeking reliable, unified classification of fire resistance and smoke control in building components. These classifications inform safety strategies, product selection, and compliance with legal regulations throughout Europe.

Key Topics

• Fire Resistance Classification: Establishes a process for classifying construction products and building elements based on performance in fire resistance tests (e.g., integrity, insulation).
• Smoke Control/Leakage: Details classification methods for smoke control based on specific measured air flow rates, enhancing protection against smoke spread.
• Loadbearing & Fire-Separating Elements: Includes classification of structural parts such as walls, floors, roofs, beams, columns, balconies, and stairs, both with and without fire-separating functions.
• Non-Loadbearing Elements: Encompasses partitions, facades, ceilings, raised floors, fire and smoke resisting doorsets, shutters, windows, conveyor system closures, seals, service ducts/shafts, and air transfer grilles.
• Fire Protection Systems: Addresses products and applications like ceilings (not independently fire resistant), fire protective coatings, claddings, and screens.
• Test Methods and Extended Applications: Cites specific test procedures and allows for classification based on direct and extended application of result data.
• Exclusions: Explicitly excludes ventilation services and specifies conditions for classifying lift landing doors, referencing relevant EN standards.

Applications

EN 13501-2:2023/FprA1 is used in the following practical scenarios across the construction industry:

• Product Certification: Manufacturers use this classification system as part of CE marking and product compliance, ensuring products meet fire safety requirements consistently across the EU.
• Building Design and Specification: Architects and engineers refer to classification data when selecting and specifying products with required fire resistance or smoke control characteristics.
• Regulatory Approvals: Building authorities rely on EN 13501-2 classifications to verify compliance with fire safety regulations for new and renovated buildings.
• Performance Assessment: Construction professionals and safety consultants assess the fire performance of elements such as fire doorsets, partitions, facades, and seals using standardized test results and classification codes.
• Extended Field of Application: The standard supports project-specific assessments, where test results for one configuration are validly extended to similar products, broadening the scope and flexibility for compliance.

Related Standards

EN 13501-2:2023/FprA1 makes use of, or is referenced alongside, several other key European and international standards:

• EN 1634-1 / EN 1634-3: Fire resistance and smoke control performance test methods for doorsets, shutters, and openable windows.
• EN 15269 Series: Extended application (EXAP) of test results for fire resistance and smoke control.
• EN 16034: Performance characteristics for self-closing devices in relation to fire and smoke doorsets.
• EN 17020 Series: Durability of self-closing mechanisms.
• EN 12605: Mechanical test methods for industrial, commercial, and garage doors and gates.
• EN 1191: Durability and repeated opening/closing tests for doorsets.
• EN 81-58: Fire testing of lift landing doors (where classified under a different scope).
• EN 15254: Extended application of fire resistance for loadbearing walls and other elements.

By following EN 13501-2:2023/FprA1, construction sector stakeholders can ensure consistent fire safety classification, facilitate regulatory compliance, and reinforce public safety in buildings across Europe.
