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.
A series of tables lists the relevant performance characteristics for load-bearing (structural) and non-structural applications for the dry, humid and exterior environments. Updated plywood tables; OSB; LVL.
Key sections to review include:
Relevant standard and performance characteristics for use in structural and non-structural applications in the various service environments:
