OSB PanelOSB produced by APA member mills is manufactured to US Voluntary Product Standard PS2 – Performance Standard for Wood-based Structural-Use Panels, PS 2-10.

US PS 2 sets the performance requirements for both OSB and plywood, based on the panels intended end use in load-bearing applications such as wall or roof sheathing and flooring use, regardless of the manufacturing method.

It covers performance requirements, adhesive bond performance, panel construction and workmanship, dimensions and tolerances, marking and moisture content for structural use panels. This performance approach is also taken by European Standards for wood-based panel products.   See the individual European standards for OSB and the overall standard for wood-based panels, EN 13986: 2004+A1 2015.

APA Performance Rated OSB has satisfied various test requirements for use as a structural panel in constructing buildings.  It also indicates that the same panels can be utilised very successfully for non-building purposes as some of the performance requirements necessary for use in building are also applicable for use in industrial applications e.g. the uniform load requirement for flooring is also a requirement for pallet decks, or the racking performance of panels used for wall sheathing is also important when producing pack cases, especially if the contents are going to be of high value.
