Testing Requirements for OSB Performance Characteristics

Testing Requirements for OSB Performance Characteristics

The UK and Europe adhere to the same standards for wood-based panels.The main OSB standard  is: EN 300 and the overall harmonised standard for wood-based panels is EN 13986: 2004+A1 2015. Refer also to our application guide, which matches performance characteristics to your specific application.

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: floors/ walls/roof ( 7); non-structural: internal  – dry (4), internal humid (5). Here’s a link if you would like this guide in table form

1 For use in humid conditions only
2  Tests for strength & stiffness in tension & compression, panel shear (Modulus of Rigidity), panel shear, planar shear (Modulus of Rigidity), & planar shear strength.  Only required for specific end-use applications. These characteristics may or may not have been tested by the manufacturer.3  Only relevant when intended for structural floor or roof decking on joists
