Five European associations have jointly urged the European Commission to establish a clear legal framework for the use of verified software tools to assess product performance under the revised Construction Products Regulation (EU) 2024/3110.
Windows, doors and flat glass are largely custom-made and project-specific. Relying on worst-case declarations and extensive physical testing would lead to a very high number of individual declarations, high costs and administrative burden, especially for SMEs. It would also strain Notified Body capacity and reduce the representativeness of declared values. Software-based calculations have been used for many years.
SBS, European Aluminium, EuroWindoor, EPPA and Glass for Europe therefore propose that the Commission amend Annex IX(5) on AVS 3 by delegated act under Article 10(4) CPR. Verified software could then be used to assess the performance of relevant essential characteristics, where foreseen in the standardisation request. A Notified Body would validate the input parameters and the software. Manufacturers would apply the tool within their factory production control.
