本欧洲标准规定了确定在杂酚油新鲜处理的木材中杂酚油的渗透和保留的参考方法，主要是为了确定经处理的木材是否符合EN 351-1的规定。它还提供了采集测试样品及其在采样和分析之间的处理方面的指导。 注意在工厂的日常实践中，可以使用其他方法（例如在处理前后称量电荷）来确定保留，条件是可以用该方法建立显着的关系

This European Standard specifies the reference methods for determining the penetration and retention of creosote in timber freshly treated with creosote, principally in order to ascertain whether the treated timber conforms to specifications written in terms of EN 351-1. It also provides guidance on the acquisition of test samples and their handling between sampling and analysis. NOTE In the day-to-day practice at the plant, other methods (e.g. weighing the charge before and after treatment) can be used for determining the retention, provided that a significant relationship can be established with this method.
