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the latest technological and market developments, and in the interest of legal clarity, Decision 2000/367/EC should be repealed.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,

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.

B. 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.

1. Load-bearing elements without a fire-separating function

Table 1

Applies to	Walls, floors, raised floors, roofs, beams, columns, balconies, walkways, stairs
R		15	20	30	45	60	90	120	180	240	360

2. Load-bearing elements with a fire-separating function

Table 2.1

Applies to	Walls
RE		15	20	30	45	60	90	120	180	240	360
REI		15	20	30	45	60	90	120	180	240	360
REI-M		15	20	30	45	60	90	120	180	240	360
REW		15	20	30	45	60	90	120	180	240	360

Table 2.2

Applies to	Floors, roofs, roof windows, rooflights and shutters
RE		15	20	30	45	60	90	120	180	240	360
REI		15	20	30	45	60	90	120	180	240	360
C	The C classification may be declared where a self-closing device is fitted and the element or product was not manually closed for the purpose of the test. Optionally, for durability of self-closing, the C classification may be complemented by the digits 0 to 5 according to the use category where cycle testing has been carried out.

Table 2.3

Notes	The classification shall be made specific depending on the exposure. The absence of the designation letter ‘r’ refers to standard temperature/time curve exposure (full fire resistance) whereas its presence refers to the constant temperature attack of 500 °C (reduced exposure). Raised floors satisfying the standard temperature/time curve exposure for a given time are considered to satisfy the reduced exposure conditions for at least the same period.
