1.1本试验方法涵盖介电分析仪在-100至300°C温度范围内的温度校准,适用于商用和定制设备。通过观察在使用温度范围内具有已知转变温度的标准参考材料的熔融转变来进行校准。
1.2可使用与本试验方法等效的电子仪器或自动数据分析和数据简化系统或处理。
1.3以国际单位制表示的数值应作为标准报告。
1.4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。
====意义和用途======
本试验方法允许仪器温标数据的实验室间比较和实验室内相关性。
介电分析仪用于表征广泛的具有介电矩的材料。
测量指定的一个期望值是试样特性发生显著变化的温度。为了从一个时间段到另一个时间段以及从一个实验室到另一个实验室获得一致的结果,必须在感兴趣的温度范围内准确校准仪器的温度信号。
1.1 This test method covers the temperature calibration of dielectric analyzers over the temperature range from -100 to 300°C and is applicable to commercial and custom-built apparatus. The calibration is performed by observing the melting transition of standard reference materials having known transition temperatures within the temperature range of use.
1.2 Electronic instrumentation or automated data analysis and data reductions systems or treatment equivalent to this test method may be used.
1.3 The values stated in SI units are to be reported as the 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 and health practices and to determine the applicability of regulatory limitations prior to use.
====== Significance And Use ======
This test method permits interlaboratory comparison and intralaboratory correlation of instrumental temperature scale data.
Dielectric analyzers are used to characterize a broad range of materials that possess dielectric moments. One of the desired values to be assigned by the measurement is the temperature at which significant changes occur in the properties of the test specimen. In order to obtain consistent results from one period of time to another and from one laboratory to another, the temperature signal from the apparatus must be calibrated accurately over the temperature range of interest.
