1.1本试验方法涵盖了在规定的实验条件下，使用热机械测量确定材料加热时的玻璃化转变温度的程序。 1.2本试验方法适用于非晶态或部分晶态材料，其在玻璃化转变以下具有足够的刚性，以抑制传感探头的压痕。 1.3正常工作温度范围为-100至600°C。该温度范围可根据所用仪器进行扩展。 1.4也可使用与本试验方法等效的基于计算机或电子的仪器、技术或数据处理。 明确建议本试验方法的用户，所有此类仪器或技术可能不是等效的。本试验方法的使用者有责任在使用前确定必要的等效性。在发生争议的情况下，只有手动程序才被视为有效。 1.5以国际单位制表示的数值应视为标准。 1.6本标准无意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和健康实践，并确定监管限制的适用性。 第7节给出了具体的预防说明。

1.1 This test method covers procedures for the assignment of the glass transition temperature of materials on heating using thermomechanical measurements under prescribed experimental conditions. 1.2 This test method is applicable to amorphous or to partially crystalline materials that are sufficiently rigid below the glass transition to inhibit indentation by the sensing probe. 1.3 The normal operating temperature range is from -100 to 600°C. This temperature range may be extended depending upon the instrumentation used. 1.4 Computer- or electronic-based instruments, techniques, or data treatment equivalent to this test method may also be used. Users of this test method are expressly advised that all such instruments or techniques may not be equivalent. It is the responsibility of the user of this test method to determine the necessary equivalency prior to use. In the case of dispute, only the manual procedures are to be considered valid. 1.5 The values stated in SI units are to be regarded as the standard. 1.6 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 and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 7.
