1.1本规程详细说明了一些热分析方法中使用的统计数据处理。 1.2该方法描述了常见的统计工具，包括平均值、标准差、相对标准差、合并标准差、合并相对标准差和最佳拟合直线，以及热分析方法中遇到的所有计算。 1.3一些热分析方法从分配给三组或多组数据对的最佳拟合直线的斜率或截距得出分析值。此类方法可能需要估计所确定斜率或截距的精度。该精度的确定不是常用的统计工具。 本规程详细说明了获取此类精度信息的过程。 1.4也可使用与本规程等效的计算机或电子仪器、技术或数据处理。 注1-明确建议本规程的用户，某些此类仪器或技术可能不等同。本标准用户有责任在使用前确定必要的等效性。 1.5国际单位制是标准。 1.6没有等同于本规程的ISO方法。

1.1 This practice details the statistical data treatment used in some thermal analysis methods. 1.2 The method describes the commonly encountered statistical tools of the mean, standard derivation, relative standard deviation, pooled standard deviation, pooled relative standard deviation and the best fit to a straight line, all calculations encountered in thermal analysis methods. 1.3 Some thermal analysis methods derive the analytical value from the slope or intercept of a best fit straight line assigned to three or more sets of data pairs. Such methods may require an estimation of the precision in the determined slope or intercept. The determination of this precision is not a common statistical tool. This practice details the process for obtaining such information about precision. 1.4 Computer or electronic-based instruments, techniques or data treatment equivalent to this practice may also be used. Note 1—Users of this practice are expressly advised that some such instruments or techniques may not be equivalent. It is the responsibility of the user of this standard to determine the necessary equivalency prior to use. 1.5 SI units are the standard. 1.6 There are no ISO methods equivalent to this practice.
