M/BC/CEN/92/21 - CPD: External finishes of wall

Purpose

The mandate M/BC/CEN/92/21 focuses on the external finishes of walls within the framework of the Construction Products Directive (CPD). It aims to coordinate and standardise aspects related to the external wall finishes to ensure consistency, safety, and performance across the European Union.

Standardisation request

This mandate requests the development of harmonised standards dealing with the materials, application, and performance of external finishes applied to walls. The standardisation efforts are to be led by the technical committee CEN/TC 227, as referenced in resolution CEN/TC 227 143/2002.

Expected deliverables

Expected deliverables from this mandate include:

• Harmonised European standards for external finishes of walls under the CPD framework.
• Technical specifications covering the properties, durability, and compatibility of external wall finishes.
• Guidelines and testing methods to assess conformity with essential requirements set out by the CPD.

Context

The Construction Products Directive (CPD) requires member states to ensure that construction products meet uniform performance criteria to facilitate free movement within the internal market. External wall finishes are critical for building durability, aesthetics, and weather protection. By standardising these finishes, the mandate supports improved safety, environmental compatibility, and market transparency in the European construction sector. The involvement of CEN/TC 227 ensures that the standards developed are in line with existing technical expertise and industry needs.
