标准摘要
[中文适用范围]： 该国际标准定义了五个使用类别，代表了木材和木基产品在世界各地可能面临的不同使用情况。 还为这些使用类定义了子类。 注：这些子类可能会也可能不会在国家或地区标准中采用，具体取决于当地的需要。 本国际标准仅适用于木材和木制品预处理的防腐剂和工艺，不适用于修复和消除木材现有损害的产品和工艺。 本国际标准的附件提供了应用用途分类来指定防腐处理、处理过的木材、天然耐用和改性木材的指南，但没有提供明确的规范。 [外文原描述]： ISO 21887:2007 defines five use classes that represent different service situations to which wood and wood-based products can be exposed all over the world. Subclasses are also defined for these use classes. ISO 21887:2007 applies only to preservatives and processes for pre-treatment of wood and wood products and is not intended for products and processes for remediation and eradication of existing damage to timber. The annex to ISO 21887:2007 provides guidance on applying use classification to specify preservative treatments, treated wood, naturally durable and modified wood but does not provide definitive specifications.
