OSB Performance Characteristics for Specific Applications

Standards and Performance Characteristics for Specific OSB Applications

The standard that classifies OSB is EN 300. Click here for the other main standards relevant to OSB panels.

This APA guide takes the hard work out of finding out which standards you need to comply with, for different elements of your building project. It identifies essential characteristics like bending strength and those which depend on the application, such as air permeability. Simply select from the list below.

To check the testing standard requirements that manufacturers carry out before creating the Declaration of Performance (DoP) on your OSB panel, view here.
