CE marking of wood based panels NS-EN 13986

CE marking of wood-based panels

CE marking of wood-based panels is based on the harmonised standard NS-EN 13986 “Wood-based panels for use in construction.

Characteristics, evaluation of conformity and marking”.

Requirements for certification

NS-EN 13986 states that in order to CE mark wood-based panels, conformity with system 2+ must be documented. This entails certification of the factory production control.

Before a certificate can be issued an initial inspection is performed, where the quality handbook, control routines and initial type testing are assessed. Based on this inspection, the certificate is issued.

Continuous surveillance is performed minimum twice a year. The inspection includes evaluation of quality documentation, evaluation of production control and test results, registration of deviations and measures taken at deviations. If a company does not correct the deviations in a satisfactory manner, the certificate may be revoked.

Treteknisk is a notified body.

Marking

Marking of wood-based panels shall be in accordance with the standard and shall include the CE mark, the manufacturer’s identification mark, nominal thickness, reference to NS-EN 13986, technical class, formaldehyde class, fire class (if any), treatment against biological attack (if relevant) and PCP (if exceeding 5 ppm).

Wood based panels with fire retardant treatment

If a producer improve the characteristics for reaction to fire by fire-retardant paint or impregnation, the system for CE marking of the product is changed from system 2+ to system 1. Then a product certificate (CE-certificate of constancy of performance) is mandatory.

Treteknisk is Notified Body for CE-certification in system 1 under EN 13986.
