The new CPR 2024 introduces a significant revision of how construction products are assessed, verified, and monitored over time. The former AVCP system (Assessment and Verification of Constancy of Performance) defined under CPR 305/2011 is replaced by the AVS Systems ( Assessment and Verification Systems ), a more comprehensive model aligned with current market needs.

What AVS Systems Are and Their Purpose

AVS Systems, described in Annex IX of CPR 2024, define the tasks required to:

• assess the declared performance of a construction product;

• ensure that such performance remains stable over time;

• verify compliance with the Regulation.

The new framework consists of six AVS systems, assigned by the European Commission through delegated acts. The assignment depends on the type of product, its potential risk, and the variability of its production process. In some cases, more than one AVS system may apply to a single product category.

For each system, manufacturers must comply with specific obligations, which may include:

• management and monitoring of the Factory Production Control (FPC);

• testing and sampling activities;

• preparation of technical documentation.

The complexity of these tasks and the involvement of a Notified Body vary depending on the applicable AVS system: the range goes from full third-party audits and testing (System 1+) to complete manufacturer self-assessment (System 4).

Common Requirements Across AVS Systems

CPR 2024 strengthens and clarifies the requirements for the Factory Production Control (FPC), which must:

• cover the entire manufacturing process, from incoming raw materials to product shipment (gate-to-gate approach);

• ensure conformity with the designated product type and the correct product category;

• include all technical elements required for applying the AVS system(s) specified in the relevant hTS or EAD.

Regardless of the AVS system, manufacturers must also:

• determine the product type and apply the appropriate category, as defined in the hTS or EAD;

• prepare technical documentation demonstrating correct performance assessment (not required for AVS 3+);

• prepare technical documentation demonstrating conformity with CPR 2024 requirements (not required for AVS 3+).

Extended Application Rules: an Alternative Assessment Method

Although CPR 2024 does not explicitly define the term extended application rules, the Regulation implies that these procedures originate from harmonised technical specifications, EADs, and harmonised standards.

These rules offer increased flexibility in performance assessment when standard test methods cannot be applied—for example, when a product’s dimensions exceed the limits of traditional test setups.

Summary: The Benefits of the New AVS Approach

With the introduction of the AVS Systems, CPR 2024 brings a significant evolution to the assessment and compliance framework. Manufacturers take on greater responsibilities, particularly in terms of sustainability and internal control, while notified bodies play a broader role—even within systems traditionally considered less demanding, such as AVS 3. The regulation also enhances clarity, transparency, and traceability across the entire evaluation and verification process. Ultimately, the goal is to ensure that construction products placed on the European market are not only compliant with regulatory requirements but also stable, reliable, and sustainable over time.
