1.1 本试验方法包括测定蜡纸表面蜡的重量。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 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 蜡纸和纸板的许多功能特性与作为表面膜存在的蜡量有关。 通过溶剂萃取测定蜡负荷的试验方法不区分作为表面蜡层存在的蜡和已渗透到基质中的蜡。该测试方法通过机械方式去除蜡，测量基材每个表面上的蜡量。

1.1 This test method covers determination of the weight of wax on the surface of waxed paper. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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 Many of the functional properties of waxed paper and paperboard are related to the amount of wax present as a surface film. Test methods which determine wax load by solvent extraction do not differentiate between the wax present as a surface wax layer and that which has penetrated into the substrate. This test method, which mechanically removes the wax, measures the amount on each surface of the substrate.
