标准摘要
[中文适用范围]： 本部分 IEC 60493 给出了可用于分析和评估老化试验结果的统计方法。它涵盖了基于正态分布试验结果均值的数值方法。这些方法仅在有关试验数据所遵循的数学和物理定律的特定假设下有效。还提供了用于验证其中一些假设有效性的统计检验。本标准处理来自完整试验集和删失试验集的数据。本标准基于第 3 条定义的“数据子组”概念提供数据处理。用于从数据组推导统计参数的计算过程中所用系数的有效性在 [1] 中进行了描述。 [外文原描述]： IEC 60493-1:2011 gives statistical methods which may be applied to the analysis and evaluation of the results of ageing tests. It covers numerical methods based on mean values of normally distributed test results. These methods are only valid under specific assumptions regarding the mathematical and physical laws obeyed by the test data. Statistical tests for the validity of some of these assumptions are also given. This standard deals with data from both complete test sets and censored test sets. This standard provides data treatment based on the concept of "data sub-group" as defined in Clause 3. The validity of the coefficients used in the calculation processes to derive statistical parameters of the data groups are described in IEC 60216-1. This second edition cancels and replaces the first edition, published in 1974, and constitutes a technical revision. The main changes with respect to the first edition are that, besides a complete editorial revision, censored data sub-group are considered.
