摘要 木材耐久性和保存领域的标准化工作在欧洲层面由欧洲标准化委员会 (CEN) 的技术委员会 TC 38“木材和木制品的耐久性”进行管理。生产可持续的木质材料具有挑战性。其提供的一个关键方面是可靠的标准，该标准考虑了最终用户的期望以及可能影响木质部件使用寿命的广泛参数，例如暴露于潮湿环境、气候变化和设计。为了实现这些目标，大多数 CEN/TC 38 标准目前正在根据木材保护领域的最新科学、技术和法律发展进行修订。人们越来越需要对建筑中的木制品进行性能分类，并从根本上考虑木材耐久性测试方法和标准如何了解使用寿命以及如何将其转化为性能分类系统。本文描述了欧洲过去 5-10 年的变化以及标准制定的轨迹现在如何走上不同的道路。描述了分类和使用寿命要求，以及考虑材料阻力、潮湿风险和现有标准适应性等关键问题的当前方法。
Abstract Standardization work in the field of wood durability and preservation is managed, at the European level, by the technical committee TC 38 ‘Durability of wood and wood-based products’ of the European Committee for Standardization (CEN). Producing sustainable wood-based materials is challenging. A crucial aspect of their provision is reliable standards that take consideration of both the expectations of end-users and the broad set of parameters that may influence the service life of wooden components such as exposure to moisture, climatic variations and design. In order to reach these objectives, most CEN/TC 38 standards are currently being revised based on the recent scientific, technological and legal developments in the field of wood protection. There is an increasing need for performance classification of wood products in construction and to radically consider how wood durability test methods and standards can inform on service life and how they might be translated into a performance classification system. This paper describes the changes during the past 5–10 years in Europe and how the trajectory of standards development is now on a different pathway. Classification and service life demands are described as well as current approaches to consider key issues such as material resistance, moisture risk and adaptation of existing standards.
