 Manufacturing Standards for US Trademarked Panels

The APA trademark on plywood and OSB panels confirms that they have been manufactured to US Product Standards PS1-09 (plywood) and PS 2-10 (plywood and OSB).

They automatically meet the requirements for use in non-construction European and UK applications, subject to the specific end use.  It is usual for some non-construction applications to have the same performance requirements as walls and floors used in construction applications.

Product Standard PS1-09 for plywood:

  • Sets minimum manufacturing requirements that cannot be varied.
  • Covers wood species, veneer grades and packaging.

Performance standard PS2-10 for both plywood and OSB panels:

  • Establishes criteria for specific applications including panel strength, stiffness, durability and stability but allows total flexibility on how this is achieved.

Both standards also:

  • Establish methods for determining the above requirements are meet or are better than the minimum levels stated in the respective product standard.
  • Use industry-standard terms and definitions.
  • Provide a quality certification programme to ensure that qualified testing agencies like APA  have checked the panels to ensure they comply with these respective standards.
  • Give guidance on
    • Adhesive bonding
    • Panel construction & workmanship
    • Dimensions & tolerances
    • Moisture content
    • Marking.
