Ply Performance Testing Requirements

Testing Requirements for Performance Characteristics in UK & European Standards

The UK and Europe adhere to the same standards for wood-based panels. The standard that classifies plywood is EN 636 and the  overall harmonised standard for wood-based panels is EN 13986: 2004+A1 2015. 

The standards set down  specific tests to ensure your selected wood-based panels deliver the right performance characteristic for your application. Our guide makes this easy for you by listing the  characteristic you want  – and tells you where to find the testing requirements. The Clause number stays the same but the Table number varies  depending on the specific application.

List of Tables: structural:  exterior (3), floors/ walls/roof ( 7); non-structural: Internal  – dry (4), internal humid (5), exterior (6¹)

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

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 strength

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

5 Relevant only for use as wind barriers.
