This European Standard is applicable to solid wood and wood-based products. This European Standard defines five use classes that represent different service situations to which wood and wood-based products can be exposed. This standard also indicates the biological agents relevant to each situation. A use class is not a performance class and does not give guidance for how long wood and wood-based product will last in service.
