电绝缘材料.耐热性能.第3部分:耐热性计算说明

[中文适用范围]： IEC 60216的本部分规定了根据IEC 60216-1和IEC 60216-2的说明获得的实验数据推导耐热特性的计算程序，使用固定老化温度和可变老化时间。实验数据可以使用非破坏性、破坏性或验证测试来获得。从无损或验证测试获得的数据可能不完整，因为到达终点所需时间的测量可能在中值时间之后但在所有样本到达终点之前的某个点终止。该过程通过工作示例进行说明，并推荐合适的计算机程序以方便计算。 [外文原描述]： IEC 60216-3:2006 specifies the calculation procedures to be used for deriving thermal endurance characteristics from experimental data obtained in accordance with the instructions of IEC 60216-1 and IEC 60216-2, using fixed ageing temperatures and variable ageing times. The experimental data may be obtained using non-destructive, destructive or proof tests. Data obtained from non-destructive or proof tests may be incomplete, in that measurement of times taken to reach the endpoint may have been terminated at some point after the median time but before all specimens have reached end-point. The procedures are illustrated by worked examples, and suitable computer programs are recommended to facilitate the calculations. The major technical changes with regard to the first edition concern an updating of Table C.2. In addition, the scope has been extended to cover a greater range of data characteristics, particularly with regard to incomplete data, as often obtained from proof test criteria. The greater flexibility of use should lead to more efficient employment of the time available for ageing purposes. Finally, the procedures specified in this part of IEC 60216 have been extensively tested and have been used to calculate results from a large body of experimental data obtained in accordance with other parts of the standard. Annex E "Computer program" has been completely reworked. Please be aware that the computer program provided in this publication is not compatible with the 64-bit version of Windows 7.
