本欧洲标准适用于实木和木制品。 本欧洲标准定义了五种使用类别，这些使用类别表示可以暴露木材和木材产品的不同服务情况。本标准还表明与每种情况相关的生物制剂。 使用类不是性能类，不能指导木材和木制品的使用寿命

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.
