Begin with the documentation
For construction products, CE marking is connected to declared performance and the applicable assessment route. The European Commission explains how harmonised standards and European Technical Assessments fit into this process.
Read what is declared
A Declaration of Performance provides information about a product's performance. Read the document with the product identification and intended use, keeping it linked to the exact product being considered.
Keep the project record clear
Request the current manufacturer documentation for the proposed product. Keep its references with the specification, and have the responsible project professional assess suitability for the intended application and local requirements.
