Official Journal EN of the European Union L series 2024/1681 13.6.2024 COMMISSION DELEGATED REGULATION (EU) 2024/1681 of 6 March 2024 supplementing Regulation (EU) No 305/2011 of the European Parliament and of the Council by establishing classes of performance in relation to the resistance to fire of construction products (Text with EEA relevance) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Regulation (EU) No 305/2011 of the European Parliament and of the Council of 9 March 2011 laying down harmonised conditions for the marketing of construction products and repealing Council Directive 89/106/EEC(1), and in particular Article 27(1) thereof, Whereas: (1) Commission Decision 2000/367/EC(2)establishes a system for classifying the performance of construction products with regard to their resistance to fire. That system is based on a harmonised solution for assessing that performance and for classifying the results of those assessments. (2) Decision 2000/367/EC does not cover certain classes of performance and thus limits the possibility to declare a more detailed performance. It is therefore necessary to establish classes of performance that are up-to-date to the latest technological and market developments. (3) New classifications for non-loadbearing elements or products with a fire-separating function applicable to unloaded roofs, non-mechanical fire barriers for ventilation ductwork, penetration seals, combined penetration seals, linear joint seals and air transfer grilles should be added. (4) The obsolete classification R for load-bearing elements with a fire-separating function applicable to floors and roofs should be removed as it is effectively covered with the table related to load-bearing elements without a fire- separating function. (5) The technical progress in the assessment methods also requires more detailed explanations and points of reference as regards the products, including revised information in notes. (6) In order to enable manufacturers to declare sufficiently detailed classes of performance of construction products with regard to their resistance to fire in line with the latest technological and market developments, and in the interest of legal clarity, Decision 2000/367/EC should be repealed. (7) In accordance with Article 27 of Regulation (EU) No 305/2011, classes of performance in relation to the essential characteristics of construction products need to be established by the Commission. In accordance with Article 27(2) of that Regulation, those classes are to be used in harmonised standards, (1) OJ L 79, 16.3.2006, p. 27. (2) Commission Decision of 3 May 2000 implementing Council Directive 89/106/EEC as regards the classification of the resistance to fire performance of construction products, construction works and parts thereof (OJ L 133, 6.6.2000, p. 26). ELI: http://data.europa.eu/eli/reg_del/2024/1681/oj 1/14EN OJ L, 13.6.2024 HAS ADOPTED THIS REGULATION: Article 1 Classes of performance in relation to the resistance to fire of construction products, as set out in the Annex, are established. Article 2 Decision 2000/367/EC is repealed. References to Decision 2000/367/EC shall be construed as references to this Regulation. Article 3 This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union. This Regulation shall be binding in its entirety and directly applicable in all Member States. Done at Brussels, 6 March 2024.

CLASSES OF PERFORMANCE IN RELATION TO THE RESISTANCE TO FIRE OF CONSTRUCTION PRODUCTS General The relevant definitions, tests and performance criteria are fully described or referenced in the European resistance to fire classification standards, harmonised European product standards, European testing standards, and relevant parts of Eurocodes. If for asymmetrical elements the declared class of the element is only valid from one side, the class shall be accompanied by this information. The following classes of performance are expressed in minutes unless otherwise specified. ELI: http://data.europa.eu/eli/reg_del/2024/1681/oj 3/14EN OJ L, 13.6.2024 1.

The classification is completed by the suffix ‘single’ for products intended for single compart­ ment use. ‘ved’, ‘vew’, ‘vedw’ and/or ‘hod’, ‘how’, ‘hodw’ show the product is intended to be used for vertical and/or horizontal use, together with mounting in a duct or in a wall/floor or both respectively. ‘H’ indicates a single compartment smoke control damper capable of satisfying integrity (E) for the classification period having a horizontal blade axis or geometry, ‘V’ indicates a single compartment smoke control damper capable of satisfying integrity (E) for the classification period having a vertical blade axis or geometry. ‘500’, ‘1 000’ and ‘1 500’ show that the product is intended to be used up to this value of under- pressure in Pa at ambient temperature. ‘AA’ denotes for use with applications providing automatic activation, ‘MA’ denotes for use with applications requiring manual intervention or providing automatic activation. ‘C ’, ‘C ’, ‘C ’ or ‘C (N)’, ‘C (N)’, ‘C (N)’ show the product is intended to be used 300 10 000 MOD 300 10 000 MOD in smoke control only systems, fully controlled smoke control systems and smoke control sys­ tems combined with environmental systems or modulating smoke control dampers intended to be used in any system having a controlled or variable position, tested under load, or without load (N), respectively. ‘HOT 400/30’ (High Operational Temperature) indicates that the single compartment smoke control damper has been subjected to an additional test to demonstrate that it has the ability to be opened and closed during a period of 30 minutes of temperatures up to 400 °C. 12/14 ELI: http://data.europa.eu/eli/reg_del/2024/1681/ojEN OJ L, 13.6.2024 Table 7.4 Applies to Multi-compartment fire resistant smoke control dampers E 15 20 30 45 60 90 120 180 240 360 EI 15 20 30 45 60 90 120 180 240 360 S 200 m3/(m2h) maximum leakage rate with reference to nominal duct cross sectional area: (a) smallest size at ambient temperature; (b) largest size at ambient temperature and during the fire test.
