本欧洲标准为确定和分类木材和木材材料对生物破坏木材的耐久性的方法提供指导。 这些方法可以应用于单独的木材种类，一批木材和加工的木质材料，包括热处理，防腐处理的木材和改性木材。然而，本标准并不旨在取代杀菌剂的功效测试。 本标准中考虑的木材破坏剂有: - 木材腐烂真菌（担子菌和软腐真菌）; - 能够攻击干木的甲虫; 白蚁 - 能够在服务中攻击木材的海洋生物。 关于欧洲国家认为具有经济重要性的所选木材的生物耐久性数据，见附录B（资料性附录），该数据还提供了有关其地理来源，密度，边材宽度和可处理性的信息。 注意处理性，破坏真菌的耐久性，水的渗透性和使用木材和木质材料的性能也是重要的问题。然而，由于目标在于评估和分类这些因素的标准化方法并不存在和/或尚未得到广泛的经验，初步指导见附件C（资料性说明）c

This European Standard gives guidance on methods for determining and classifying the durability of wood and wood-based materials against biological wood-destroying agents. The methods can be applied either to individual wood species, batches of wood and processed wood-based materials, including heat-treated, preservative-treated wood and modified wood. However, this standard is not intended to replace testing of the efficacy of biocides. The wood-destroying agents considered in this standard are: — wood-decay fungi (basidiomycete and soft-rot fungi); — beetles capable of attacking dry wood; — termites; — marine organisms capable of attacking wood in service. Data on the biological durability of selected wood species considered of economic importance in European countries are presented in Annex B (informative), which also provides information relating to their geographical origin, density, sapwood width and treatability. NOTE Treatability, durability to disfiguring fungi, permeability to water and performance in use of wood and wood-based materials are also important issues. However, because standardized methods aiming to assess and classify these factors do not exist and/or have not been extensively experienced yet, preliminary guidance is given in Annex C (informative) for the classification of wood treatability with aqueous wood preservatives, Annex D (informative) for the classification of the permeability to water, Annex E (informative) for the durability to disfiguring fungi, and Annex F (informative) for the classification of performance.
