1.1 本试验方法描述了在-100°C至300°C的温度范围内使用热滞后对动态机械分析仪进行温度校准。 1.2 本标准可与试验方法进行比较 E1867 . 1.3 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。 1.4 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。 1.5 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 动态力学分析监测材料的粘弹性特性（即储能模量、损耗模量、切角增量）随温度和频率的变化，提供了量化这些变化的方法。在许多情况下，要分配的值是正在研究的过渡或事件的温度。因此，动态力学分析热曲线的温度轴（横坐标）必须通过调整测量的温度标度来精确校准，以匹配所需温度范围内的假设试样温度。

1.1 This test method describes the temperature calibration of a dynamic mechanical analyzer using thermal lag over the temperature range of –100 °C to 300 °C. 1.2 This standard may be compared to Test Methods E1867 . 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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. 1.5 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 analysis monitors changes in the viscoelastic properties (that is, storage modulus, loss modulus, tangent angle delta) of a material as a function of temperature and frequency, providing a means to quantify these changes. In many cases, the value to be assigned is the temperature of the transition or event under study. Therefore, the temperature axis (abscissa) of the dynamic mechanical analysis thermal curve must be accurately calibrated by adjusting the measured temperature scale to match the assumed specimen temperature over the temperature range of interest.
