The European Construction Products Regulation (CPR) prescribes mandatory CE marking for all construction products permanently installed in a building. Engineered, load-bearing wood products constitute the central material for modern timber construction. Since these products are permanently installed in buildings, a CE certification is an essential prerequisite for placing them on the market.
CE certification of engineered wood products and wood based panels
Engineered wood products are assigned to the AVCP-System 1 in accordance with the requirements of the Commission, which means that an initial inspection of the product must be carried out by a product certification body notified for the respective product group. On the basis of the initial inspection of the product as well as the positive acceptance of the production and the factory production control, the notified product certification body issues a CE certificate of conformity. Based on the CE conformity certificate, the manufacturer can affix the CE marking on the product and issue the declaration of performance for their product.
The production of the engineered wood products has to take place based on harmonized regulations. The production and performance requirements for glued laminated timber and laminated beams are regulated in harmonized standard EN 14080; those for finger-jointed solid wood in EN 15497.
The requirements for cross-laminated timber are regulated in company-specific European technical assessments (ETAs) which are issued by a technical assessment body on the basis of European technical assessment document 130005-00-0304.
Wood based panels used in construction are regulated in the harmonized standard EN 13986. In contrast to the glued solid wood products, the AVCP System 2+ is provided for this product group, provided that they are used as a structurally load-bearing component, which means that the requirements of the factory production control are checked in the course of the CE certification.
After the CE certificate of conformity has been issued, a regular, six-monthly monitoring is carried out by the notified body.
Holzforschung Austria is notified for all of the harmonized regulations mentioned and has been carrying out CE certification for all product groups at home and abroad for years.

Cross-laminated timber
After obtaining a company-specific ETA from a technical assessment body, a test plan is issued by it, which regulates the requirements of the factory production control for the respective product as well as the product tests to be carried out in the course of certification by the notified body. These are carried out by us in our laboratory.
Finger-jointed solid wood
When producing finger-jointed solid wood in accordance with EN 15497, proof must be provided in the course of the initial test that the maximum cross-section that is to be produced on the respective finger jointing system achieves the required strength. The bending tests required for this can be carried out in any desired dimension in our laboratory.
Glued laminated timber, glued laminated beams, composite components made of glued laminated timber and universal finger joints in glued laminated timber
Based on EN 14080, we carry out the initial inspection, the initial test of the adhesive strength of the finger joints and the bonding strength. For universal finger joints, we determine the required characteristic values on our test field.
Plywood, particle board, MDF-panels, OSB and solid wood boards
The CE certification of wood-based materials by a notified body is only intended for use as a structural load-bearing component or as a component with increased fire behaviour requirements. The production of the different product groups takes place according to the relevant product standards; the requirements of the initial test and the factory production control depend on the respective product group. Common to all is regular evidence of formaldehyde emissions.
