IEC 61710:2013规定了估计幂律模型参数、提供故障强度置信区间、提供未来故障时间预测区间以及测试幂律模型与可修复部件数据拟合优度的程序。假设已从一个项目或在相同条件（例如环境和负载）下运行的一些相同项目中收集了失效时间数据。第二版取消并取代2000年出版的第一版，构成技术修订版。与上一版相比，主要变化如下:增加了关于幂律模型贝叶斯估计的附录C。 关键词:幂律模型、贝叶斯估计、可修件可靠性

IEC 61710:2013 specifies procedures to estimate the parameters of the power law model, to provide confidence intervals for the failure intensity, to provide prediction intervals for the times to future failures, and to test the goodness-of-fit of the power law model to data from repairable items. It is assumed that the time to failure data have been collected from an item, or some identical items operating under the same conditions (e.g. environment and load). This second edition cancels and replaces the first edition, published in 2000, and constitutes a technical revision. The main changes with respect to the previous edition are listed below: the inclusion of an additional Annex C on Bayesian estimation for the power law model. Keywords: power law model, Bayesian estimation, reliability of repairable items
