Performance Characteristics, Requirements of EN 300, EN 13896

This guide shows the requirements of OSB standard EN 300 as given in the harmonised European Standard EN 13986:2004+A1:2015 (updated).

Performance characteristics for different structural and non structural use are matched with the relevant EN 13986 tables  and corresponding clauses.

Shaded cells indicate the essential characteristics which must be determined
Non-shaded cells  give performance characteristics, determined only if required.
