1.1 本试验方法描述了使用超高分子量聚乙烯作为参考材料，在21°C下对商用或定制动态机械分析仪（DMA）的损耗模量标度进行性能确认或一致性测量。 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、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====== 5.1 本试验方法证明了动态机械分析仪在21°C等温温度下的一致性。 5.2 动态力学分析实验通常使用线性温度变化。本试验方法不涉及温度变化对损耗模量的影响。 5.3 该测试方法可用于研发、规范验收和质量控制或保证。

1.1 This test method describes the performance confirmation or measurement of conformance for the loss modulus scale of a commercial or custom-built dynamic mechanical analyzer (DMA) at 21 °C using ultra-high molecular weight polyethylene as a reference material. 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, 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 ====== 5.1 This test method demonstrates conformity of a dynamic mechanical analyzer at an isothermal temperature of 21 °C. 5.2 Dynamic mechanical analysis experiments often use linear temperature change. This test method does not address the effect of that change in temperature on the loss modulus. 5.3 This test method may be used in research and development, specification acceptance, and quality control or assurance.
