1.1 本规程涵盖了对木质基材上的透明工厂涂层系统的评估。 1.2 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 3.1 与指南一起使用时 D333 ，该实践将提供对化学试剂和家用化学品引起的污渍的抗性的综合评估。 3.2 这种做法仅适用于以足够数量涂敷以形成连续薄膜的涂层。建议报告被测涂层的干膜厚度。 3.3 根据本规程进行的染色试验结果可区分涂层之间的差异。

1.1 This practice covers evaluation of clear factory-applied coating systems on wood substrates. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 3.1 When used in conjunction with Guide D333 , this practice will provide a comprehensive evaluation of resistance to stains caused by chemical reagents and household chemicals. 3.2 This practice applies only to coatings applied in sufficient quantity to form a continuous film. It is recommended that the dry film thickness of the coating under test be reported. 3.3 Results from stain tests conducted in accordance with this practice distinguish differences between coatings.
