1.1 本试验方法描述了使用小体积同心圆筒、旋转粘度计和140°C温度浴测定聚乙烯蜡的粘度。 1.2 以国际单位制表示的数值应视为标准值。括号中的单位是为方便用户而提供的，不是标准单位。 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、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（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====== 4.1 本试验方法用于确定蜡的物理性质，并可确定蜡的用途，同时也是一项重要的质量控制试验。

1.1 This test method describes the determination of the viscosity of polyethylene wax using small-volume, concentric cylinder, rotational viscometer and a temperature bath at 140 °C. 1.2 The values stated in SI units are to be regarded as standard. The units in parentheses are provided for user convenience and are not 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, 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 ====== 4.1 This test method is used to determine a physical property of a wax and may determine the utility of the wax, as well as being a significant quality control test.
