Performance Characteristics – Requirements of EN 636 according to the updated EN 13986:2004+A1:2015

This guide shows the requirements of plywood standard EN 636 as given in the harmonised European Standard EN 13986:2004+A1:2015 (updated).  See here standards to determine performance characteristics of specific end use applications.

Shaded cells: refer to essential characteristics which must be determined.

Non-shaded cells:  refer to performance characteristics determined only if required.

Notes:

1 Plywood should be used out of direct contact with the ground, soil or water

2 For use in humid conditions only

3 Tests for strength & stiffness in tension & compression, panel shear (Modulus of Rigidity), panel shear, planar shear (Modulus of Rigidity), & planar shear stregth

4 Only relevant when intended for structural floor or roof decking on joists

5 Relevant only for use as wind barriers.
