1.1 本试验方法描述了热机械分析仪的温度校准 −50°C至1500°C。（请参见 注1 ） 1.2 以国际单位制表示的数值应视为标准。本标准中不包括其他计量单位。 1.3 警告-- 汞已被许多监管机构指定为一种可能导致严重医疗问题的危险物质。汞或其蒸汽已被证明对健康有害，对材料具有腐蚀性。处理汞和含汞产品时要小心。有关更多信息，请参阅适用的产品安全数据表（SDS）。 当地或国家法律有可能禁止销售含汞或含汞产品，或两者兼有。用户必须确定在其所在地销售的合法性。 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。 第节中给出了具体的预防说明 7. 和 附注12 。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 5.1 热机械分析仪用于各种操作模式（渗透、膨胀、弯曲等），以表征各种材料。在大多数情况下，在热机械测量中指定的值是所研究的转变（或事件）的温度。因此，所有TMA热曲线的温度轴（横坐标）必须通过直接读取温度传感器或通过调整编程器温度以匹配感兴趣的温度范围内的实际温度来精确校准。

1.1 This test method describes the temperature calibration of thermomechanical analyzers from −50 °C to 1500 °C. (See Note 1 .) 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 Warning— Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Use caution when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for additional information. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. Users must determine legality of sales in their location. 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. Specific precautionary statements are given in Section 7 and Note 12 . 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 Thermomechanical analyzers are employed in their various modes of operation (penetration, expansion, flexure, etc.) to characterize a wide range of materials. In most cases, the value to be assigned in thermomechanical measurements is the temperature of the transition (or event) under study. Therefore, the temperature axis (abscissa) of all TMA thermal curves must be accurately calibrated either by direct reading of a temperature sensor or by adjusting the programmer temperature to match the actual temperature over the temperature range of interest.
