1.1本试验方法评估了木材在外部暴露之前或之后的透明拒水涂层的有效性。 1.2本试验方法的实验室内结果可用于比较透明拒水涂料的有效性。除非使用已知的防水剂作为参考，否则在不同实验室获得的结果之间的一致性可能不太令人满意。 1.3本标准无意解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 This test method evaluates the effectiveness of clear water repellent coatings on wood before or after exterior exposure. 1.2 Intralaboratory results with this test method can be used to compare the effectiveness of clear water repellent coatings. The agreement between results obtained in different laboratories may be less satisfactory unless a known water repellent is used as a reference. 1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
