EN 13986 : 2004 +A1:2015   Wood-based panels for use in construction – Characteristics, evaluation of conformity and marking

EN 13986 is the harmonised European standard for wood-based panels.  It defines the performance characteristic and test methods for wood-based panels (including plywood, OSB and LVL) enabling their use in construction applications. Compliance confers a presumption of ‘fitness for purpose’ for a particular, intended end use.

See tables for plywood; OSB; LVL giving the relevant performance characteristics for load-bearing (structural) and non-structural applications for the dry, humid and exterior environments. See guide to tables giving end use and service conditions.

Important standard sections include:

Specific 2015 amendments include racking resistance, embedment strength, air permeability; additional info on dangerous substances and terminology reflecting CPR requirements.

  • The system of assessment and verification of constancy of performance with compliance demonstrated by factory production control, determination of product type, initial factory inspection and continuous surveillance of the factory production control. Certificate of conformity and Declaration of Conformity.
  • Trademarks; CE marking (Annex ZA (informative) Section ZA.3 covers the CE marking of panels).
