Relevant EU Standards for OSB
The main OSB standard is: EN 300: Oriented Strand Boards (OSB) – Definitions, classification and specifications. However, all OSB products used in European construction must comply with the overall standard for wood-based panels, EN 13986: 2004+A1 2015, now updated (key amendments).
OSB panel performance characteristics:
- Guide to EN 13986 tables listing performance characteristics for load-bearing (structural) and non-structural applications for the dry, humid and exterior environments.
- Performance characteristics for different applications – and the related European standards.
Use Classes and Service Classes:
- Additional moisture content guidance and aligning Use and Service Classes.
- The term ‘Hazard Class’ has been replaced by ‘Use Class’ in the updated EN 335:2013 and these are relevant to all types of panels, not OSB specifically.
Seven other relevant standards for using OSB in Europe:
EN 319: Particleboards and fibreboards – Determination of tensile strength perpendicular to the plane of the board
EN 789: Timber structures – Test methods – Determination of mechanical properties of wood-based panels
EN 1058: Wood-based panels – Determination of characteristic 5 percentile values and characteristic mean values
EN 12369-1: Wood-based Panels – Characteristic Value for Structural Design – OSB, particleboard and fibreboards
EN 12871: Wood-based panels – Performance specifications and requirements for load bearing boards for use in floors, walls and roofs
PD CEN/TR 12872: Wood-based panels – Guidance on the use of load-bearing boards in floors, walls and roofs
