THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Regulation (EU) 2024/3110 of the European Parliament and of the Council of 27 November 2024 laying down harmonised rules for the marketing of construction products and repealing Regulation (EU) No 305/2011, and in particular Article 5(5), third subparagraph thereof,

Whereas:

(1) In order to enable manufacturers to declare sufficiently detailed classes of performance of products within the harmonised zone established pursuant to Article 11 of Regulation (EU) 2024/3110, it is necessary to establish classes of performance that are aligned to the latest technological and market developments.

(2) Classes of performance in relation to the essential characteristic reaction to fire were established by Commission Delegated Regulation (EU) 2016/364 on the basis of Regulation (EU) No 305/2011 of the European Parliament and of the Council. However, those classes of performance are not applicable under Regulation (EU) 2024/3110. Therefore, in order to keep the continuity of the system, the CPR Acquis Expert Group advised the Commission to establish the same classes of performance set out by Delegated Regulation (EU) 2016/364.

(3) The Commission should therefore determine the classes of performance to be used for the declaration of the essential characteristic reaction to fire,

HAS ADOPTED THIS REGULATION:

Article 1

The classes of performance in relation to the essential characteristic reaction to fire of products shall be those set out in the Annex.

Article 2

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, 13 February 2026. For the Commission The President Ursula von der Leyen

B.

DEFINITIONS For the purposes of this Annex the following definitions apply:

(1) material means a single basic substance or uniformly dispersed mixture of substances;

(2) homogeneous product means a product consisting of a single material, having uniform density and composition throughout the product;

(3) non-homogeneous product means a product that does not satisfy the requirements of a homogeneous product and that is composed of one or more components, substantial and/or non-substantial;

(4) substantial component means a material that constitutes a significant part of a non-homogeneous product. A layer with a mass per unit area ≥ 1,0 kg/m2 or a thickness ≥ 1,0 mm is considered to be a substantial component;

(5) non-substantial component means a material that does not constitute a significant part of a non-homogeneous product. A layer with a mass per unit area < 1,0 kg/m2 and a thickness < 1,0 mm is considered to be a non- substantial component. Two or more non-substantial layers that are adjacent to each other, where there are no substantial components in between the layers, are considered as one non-substantial component and are classified in accordance with the criteria for a layer that is a non-substantial component;

(6) internal non-substantial component means a non-substantial component that is covered on both sides by at least one substantial component;

(7) external non-substantial component means a non-substantial component that is not covered on one side by a substantial component.
