European Commission Establishes Assessment and Verification Systems for Construction Product Families and Categories under Regulation (EU) 2024/3110

On August 28, 2026, the European Commission published Commission Delegated Regulation (EU) 2026/1310, supplementing Regulation (EU) 2024/3110 by establishing the applicable assessment and verification systems for construction product families and categories. The Regulation assigns systems according to product family, category, intended use, essential characteristics and product requirements. The annex covers a broad range of construction products and distinguishes assessment intensity according to the relevant performance or requirement. Examples include System 1+ for certain fire-related performance of power, control and communication cables; System 3+ for environmental sustainability; System 2+ for specified dangerous-substance characteristics; and System 3 for certain emissions of dangerous substances into indoor air. The Regulation also establishes rules for cases where deemed-to-satisfy provisions apply and provides for different systems within the same product family or category depending on the characteristic concerned. It enters into force on September 17, 2026, and is binding in its entirety and directly applicable in all Member States.

Impact

Impact assessment: Medium. Key reasons: the Regulation is binding and establishes the assessment and verification route that will apply to construction product families and categories under Regulation (EU) 2024/3110, but it provides a defined implementation period before entry into force.

Who is affected?

Manufacturers, importers, notified bodies and other conformity-assessment actors dealing with covered construction products.

Conclusion:

affected companies should map their products against Annex I, identify the applicable assessment and verification system for each relevant essential characteristic, and align technical documentation and conformity-assessment planning before September 17, 2026.
