UK and EU Standards for OSB
The UK has adopted the same EU standards for using OSB in construction and continues to accept the CE mark until January 2023.
OSB products must comply with the overall harmonised (EU) or designated (UK) standard for wood-based panels, (BS) EN 13986: 2004+A1 2015.
The standard that classifies OSB: (BS) EN 300: Oriented Strand Boards (OSB) – Definitions, classification and specifications.
Finding the right standard for your application – APA’s easy-to-use guide to help you match the right standard you need to comply with for a specific performance characteristic and application.
(BS) EN 335:2013 provides moisture content guidance and Use and Service Classes. Use classes have replaced ‘hazard class’. Your APA guide, here.
