Wood-Based Products: EU Standards & Regulations

In Europe, wood-based construction products must follow regulations and performance-based standards which cover:

EN standards assess a product’s essential performance characteristics.  This provides a technical and legal basis for manufacturers to use when testing the performance of their products, regardless of how they are manufactured.  Learn more from APA about selecting the right standard for your application.

Several APA member mills manufacture panel products which conform to the harmonised European standard EN 13986:2004+A1:2015.  They can therefore be CE marked in accordance with the 2013 Construction Products Regulation (CPR).

The CPR sets down new legal responsibilities for manufacturers, importers and suppliers.  It is mandatory for all wood-based products to be CE marked and manufacturers must produce an official Declaration of Performance (DoP) about a specific product and the performance characteristics for its intended end-use.

The internationally followed Environmental Product Declaration (EPD) provides information on a product’s environmental impact.  In the CPR, an EPD is used to assess the impact of a product on sustainable construction. The American Wood Council has produced four EPD relating to plywood, OSB, and LVL which are compatible with CPR requirements.

Related APA Standards

APA products conform to the official US voluntary product and performance based standards for structural wood products. US Product Standard PS 1-09 covers plywood manufacture and US Product Standard PS 2-10 sets the performance requirements for both OSB and plywood, based on the panels intended end use. APA has its own Performance-Rated Panel Standard – PRP 108 and the association’s  approach is similar to that of Europe. (The APA standard is similar to the US Product Standard PS 2-10.)

The association operates one of the most stringent schemes of third-party quality control testing and certification in the global structural panel industry.  The quality of its third party certification for its member mills is reflected in the acceptance of APA products, and their applications, by international regulatory bodies, such as the official European Standards Organisations.
