1.1 本试验方法包括测定瓦楞纸板表面涂层中蜡的重量。该方法适用于通过窗帘涂层、辊涂或其他方法涂蜡的板材；基板的结构中可能含有或不含有浸渍（饱和）蜡。 注1: 如果已知试样只有涂层蜡，没有内部饱和蜡，则可通过试验方法确定施加的总涂层蜡 D3344 . 1.2 以国际单位制表示的数值应视为标准值。 1.2.1 例外情况- 括号中给出的非国际单位仅供参考。 1.3 本标准并非旨在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。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 蜡涂层应用于瓦楞纸板，以提供更好的防潮或其他剂，或提供更好的外观或耐磨性。这些性能特征受表面蜡含量的影响。 5.2 在大多数涂层操作过程中，所涂蜡的大部分会在表面凝结，而少量会迁移并嵌入饰面的纤维中。该方法仅测量表面上的部分。

1.1 This test method covers determination of the weight of wax that is present as a coating on the surface of corrugated board. This method is applicable to board to which wax has been applied by curtain coating, roll coating, or other methods; the substrate board may or may not contain impregnating (saturating) wax within its structure. Note 1: If it is known that the specimen has coating wax only, with no internal saturating wax, the total coating wax applied may be determined by Test Method D3344 . 1.2 The values stated in SI units are to be regarded as standard. 1.2.1 Exception— Non-SI units given in parentheses are provided 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 and health 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 ====== 5.1 Wax coatings are applied to corrugated board to provide a better barrier against moisture or other agents or to provide improved appearance or abrasion resistance. These performance features are influenced by the amount of wax present on the surface. 5.2 During most coating operations, the major portion of the wax applied will congeal on the surface, while a minor proportion will migrate into and become embedded in the fibers of the facing. This method measures only the portion on the surface.
