Overview to Construction Products Regulation

Guide to Placing Declarations of Performance (DoP) Info on websites

The 2013 Construction Products Regulation (CPR) sets down new legal responsibilities for manufacturers, importers and suppliers.  It is now mandatory for all wood-based products to be CE marked. 

The CPR requires a manufacturer to produce an official Declaration of Performance (DoP) about a specific product and the performance characteristics for its intended end-use.  DoPs can now be made available by  on a manufacturer’s website . See APA’s guide to how to do this.  The EU has also introduced greater flexibility when drawing up a DoP. Learn more.

Also see joint guide from the Construction Products Association, British Board of Agrément, British Standards Institution and the Building Research Establishment.

The CPR has introduced seven ‘Basic Requirements for Construction Works’ (BRCW), of which the new BRCW No. 7 and the expansion of BRCW No. 3 define relevant product-specific information involving the life-cycle approach.

New system to assess product conformity

The six categories of the Attestation of Conformity are replaced by five categories in  an ‘Assessment and Verification of Constancy of Performance’ (AVCP) .  Specific APA Member mills supply products carrying CE marking under:

  • AVCP CE 2+ (structural) and
  • CE 4 (non-structural).
Summary of changes include:
  • Replaced: Attestation of Conformity (AoC) = 1+,  1,  2+,  2 (not relevant to timber),  3 & 4 systems.
  • New: Assessment and Verification of Constancy of Performance (AVCP) = 1+,  1,  2+,  3 & 4 systems.
  • Product marked under AVCP system CE 2+ for structural use can also be used for non-structural applications.
  • However, products marked under AVCP system CE 4 can only be used for non-structural applications.
