IEC 60216的本部分规定了根据IEC 60216-1和IEC 60216-2[1]1的说明，使用固定老化温度和可变老化时间，从获得的实验数据推导耐热性特性所用的计算程序。实验数据可通过无损、破坏性或验证性试验获得。从无损检测或验证试验中获得的数据可能不完整，因为在中值时间之后但在所有试样达到终点之前的某个点，可能会终止对达到终点所需时间的测量。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This part of IEC 60216 specifies the calculation procedures used for deriving thermal endurance characteristics from experimental data obtained in accordance with the instructions of IEC 60216-1 and IEC 60216-2 [1]1, using fixed ageing temperatures and variable ageing times.The experimental data can be obtained using non-destructive, destructive or proof tests. Data obtained from non-destructive or proof tests can be incomplete, in that it is possible that measurement of times taken to reach the end-point will have been terminated at some point after the median time but before all specimens have reached end-point.All current amendments available at time of purchase are included with the purchase of this document.
