1.1 这些试验方法描述了动态机械分析仪（DMA）从-100的温度校准 °C至300 摄氏度。 1.2 以国际单位表示的数值视为标准值。本标准不包括其他计量单位。 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（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 动态力学分析仪监测材料粘弹性特性随温度和频率的变化，提供量化这些变化的方法。在大多数情况下，要指定的值是正在研究的转变（或事件）的温度。因此，必须通过调整表观温度标度来精确校准动态力学分析热曲线的温度轴（横坐标），以匹配相关温度范围内的实际试样温度。 5.2 此测试方法对于研究、质量保证和规范验收非常有用。

1.1 These test methods describe the temperature calibration of dynamic mechanical analyzers (DMA) from –100 °C to 300 °C. 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 Dynamic mechanical analyzers monitor changes in the viscoelastic properties of a material as a function of temperature and frequency, providing a means to quantify these changes. In most cases, the value to be assigned is the temperature of the transition (or event) under study. Therefore, the temperature axis (abscissa) of dynamic mechanical analysis thermal curves must be accurately calibrated by adjusting the apparent temperature scale to match the actual specimen temperature over the temperature range of interest. 5.2 This test method is useful for research, quality assurance, and specification acceptance.
